INTRODUCTION  
1
The 3Com® TokenLink® VelocityISA network interface  
card (NIC) is a high-performance card for PCs with an  
Industry Standard Architecture (ISA) bus or Extended  
Industry Standard Architecture (EISA) bus. This NIC is  
referred to as the 3C319 NIC in this guide.  
High-Performance Features  
The 3C319 NIC is designed for high network  
performance and trouble-free operation. This section  
describes the performance features of the 3C319 NIC.  
DynamicAccess Class of Service  
3Coms DynamicAccessfeatures optimize network  
performance. With the DynamicAccess Class of Service  
feature, you can select the applications—such as  
multimedia sessions-—that require the highest-priority  
access to your network. Based on your selection, the  
network device driver recognizes high-priority applications  
and prioritizes their data transmissions.  
The NIC implements dual queues to ensure that  
high-priority traffic gets transmitted before normal-priority  
traffic. When high-priority traffic is available for  
transmission, a high-priority token is requested.  
Parallel Tasking Architecture  
Parallel Tasking® architecture provides the industrys  
fastest performance by pipelining data between the PC  
and the network. Parallel Tasking technology improves  
network data throughput by overlapping processing  
tasks to speed data transmission and reception.  
 
1-2  
CHAPTER 1: INTRODUCTION  
For example, the 3C319 NIC begins writing the first  
portion of a data frame to the network before it has  
completed reading it from PC memory.  
Full-Duplex/Dedicated Token Ring Support  
Full-duplex/Dedicated Token Ring (DTR) is an  
enhancement to the IEEE 802.5 standard that allows  
a 16 Mbps switch port to be dedicated to a station.  
In full-duplex mode, a station can simultaneously  
transmit and receive independent data streams for  
potential data throughput of 32 Mbps. The 3C319 NIC  
operates in full-duplex mode when attached to a  
DTR switch.  
Other Features  
100% compatibility with IBM legacy drivers  
and applications  
Full connectivity with IBM AS/400 and mainframe  
computers  
Plug and Play installation for ease of use in many PCs  
and advanced operating systems  
AutoLinksoftware for easy installation of NetWare  
16-bit client drivers  
Universal boot PROM for booting your computer  
remotely from a network server  
Diagnostic programs to aid problem solving  
CISPR B and FCC B certification for reduced  
electromagnetic interference when using either  
shielded twisted-pair (STP) or unshielded twisted-pair  
(UTP) cables  
Data rates of 4 or 16 Mbps over STP or UTP cables  
Auto ring speed detection option that permits the  
NDIS 4 driver for Windows 95 and Windows NT to  
detect and operate at the current ring data rate  
 
Other Features  
1-3  
Promiscuous mode support for the Windows 95 and  
Windows NT NDIS miniport drivers. In promiscuous  
mode, the NIC receives and forwards all network  
packets that arrive, regardless of the node to which  
they are addressed. Applications such as Microsoft  
Systems Management Server require the driver to be  
in promiscuous mode while they run. Promiscuous  
mode is automatically enabled and controlled by  
applications that require this feature. No user  
control is necessary.  
Easy configuration in 3Com mode for highest  
performance, or IBM mode with legacy IBM drivers  
3Com mode provides significant performance  
improvements by implementing Parallel Tasking  
architecture. Additionally, 3Com mode improves  
configuration flexibility by increasing the number  
of available IRQ channels to 8 and the number of I/O  
base addresses to 31. You can install up to six NICs  
per PC.  
IBM mode provides the same configuration options as  
IBM 16/4 Token Ring adapters: four IRQ channels and  
two I/O base addresses. You can use either 3Com  
drivers or IBM drivers in the IBM mode.  
Support for the following PC and network  
operating systems:  
MS-DOS version 3.2 or later (Microsoft DOS LAN  
Manager, Banyan VINES DOS workstation, Banyan  
VINES 386 Server, IBM PC LAN Program, Novell  
NetWare DOS Requester, IBM DOS LAN Requester)  
NetWare 2.1x or 2.2 (Novell NetWare 286 Server)  
NetWare 3.1x, 4.1x, or later (Novell NetWare

Server/LAN Requester, Communications Manager)  
MS-OS/2 version 1.x or later (Microsoft OS/2  
LAN Manager)  
IBM OS/2 Warp or OS/2 Warp Connect  
100% IBM Compatibility  
The 3Com TokenLink Velocity ISA NIC is 100%  
compatible with any commercially available driver  
or application that functions with the legacy TROPIC  
chip-based IBM adapters.  
If a 3Com TokenLink Velocity ISA NIC is not 100%  
compatible (as defined above) with any driver or  
application written to function on any IBM ISA Token  
Ring adapter, 3Com will refund the purchase price of  
the NIC.  
If you believe your TokenLink Velocity ISA NIC is  
not compatible, contact the support group of the  
organization from which you purchased the NIC.  
For information about 3Com technical support,  
see Appendix B.

3 Remove the 3C319 NIC from its antistatic container.  
4 Inspect the 3C319 NIC for visible signs of damage.  
If you find a problem, immediately notify your authorized  
network supplier and the carrier that delivered the NIC.  
Complete the Product Registration Card and return  
it to 3Com. Or call 1-800-NET-3Com for immediate  
registration.  
Inserting the 3C319 NIC  
Follow these steps to insert the 3C319 NIC:  
1 Insert the 3C319 NIC in an empty ISA or EISA  
expansion slot.  
Make sure it is completely seated in the slot by pushing  
down firmly on both ends of the NIC.  
2 Connect one of the following network cable types  
to the 3C319 NIC:  
Shielded twisted-pair (STP) cable with a  
DB-9 connector  
Unshielded twisted-pair (UTP) cable with an  
RJ-45 connector  
CAUTION: Connect the cable only to the 3C319 NIC  
that you have just installed. Connecting the cable to  
other NICs could cause serious damage to them and  
the token ring network.  
TokenLink Velocity NICs support industry-standard token  
ring Category 3, 4 or 5 UTP or types 1 or 6 STP cabling.  
These cables meet IEEE 802.5 specifications.  
Do not daisy-chain token ring NICs or connect them  
back to back.  
 
2-4  
CHAPTER 2: INSTALLING THE 3C319 NIC  
3 Connect the other end of the cable to a network  
dual access unit (DAU), a multistation access unit  
(MAU), controlled access unit (CAU), or a token  
ring switch.  
The 3C319 NIC can operate in full-duplex mode when  
attached to a Dedicated Token Ring (DTR)-enabled switch.  
4 Plug in the PC and turn the power on.  
The next step is to verify that the PC operating system  
recognizes the 3C319 NIC as a new device and  
configures it. If the operating system cannot automatically  
configure the NIC, you must configure it manually.  
Before Configuring the NIC and Installing the Driver  
After you have installed the 3C319 NIC in your PC, the  
next step is to configure the NIC and install the network  
driver for your environment.  
For some operating systems, NIC configuration and  
driver installation are automatic; for others, you need to  
manually configure the NIC before installing the driver.  
Most PCs produced after 1995 include Plug and Play  
(PnP) capabilities. When you turn on the computer  
after installing the NIC, PnP assigns settings to the  
following resources:  
I/O base address  
Interrupt request level  
BIOS/MMIO base address  
Shared RAM address  
The configuration parameters are set initially by 3Com.  
Table 2-1 lists the default settings of the 3C319 NIC  
at shipment.

If your PnP PC does not detect and automatically  
configure the 3Com NIC, do not assume the NIC is  
defective. The BIOS PnP may be an early design, or  
the design may be nonstandard. Use the procedures in  
Chapter 5, “Configuring the NIC Manually,to disable PnP  
and configure the NIC.  
Proceed with NIC configuration and driver installation  
according to the conditions described below:  
If you have a single 3C319 NIC installed and want to  
load a single NetWare DOS ODI client, see Chapter 3,  
“Installing NetWare DOS Clients Automatically.”  
Chapter 3 describes using the 3Com AutoLink utility  
to configure the NIC automatically and install the  
DOS 16-bit client network driver for NetWare 3.12  
and 4.10 systems.

NET.CFG files. (The previous versions of these files  
are renamed CONFIG.3CM, AUTOEXEC.3CM,  
and NET.3CM.)  
The AutoLink configuration utility is a DOS application.  
It cannot run in PCs running OS/2, Windows 95, or  
Windows NT.  
 
3-2  
CHAPTER 3: INSTALLING NETWARE DOS CLIENTS AUTOMATICALLY  
Before Using the AutoLink Configuration Utility  
Make sure that the following steps have been performed  
before using the AutoLink configuration utility:  
The NIC is installed in your DOS-based PC and is  
connected to the network.  
NetWare version 3.12 or later is installed on the server  
(if necessary).  
A NetWare server account is available with a user ID  
and password.  
DOS version 3.2 or later is installed on the client PC.  
Modifying AutoLink Default Settings  
A 3INSTALL.BAT file in the LOGIN directory of the  
NetWare server allows the AutoLink configuration  
program to download the NetWare client software from  
the server instead of from TokenDisk diskette #1. Your  
system administrator can create a 3INSTALL.BAT file that  
copies specific software from the server to customize  
your installation.  
Use the AUTOLINK.CFG file to modify the AutoLink  
configuration process. The AUTOLINK.CFG file in  
the AUTOLINK directory on TokenDisk diskette #1  
contains default settings and descriptions of the  
AUTOLINK.CFG parameters.  
Avoiding Memory Manager Conflicts  
The NIC uses areas of upper memory to transfer data. If  
you are using a memory manager such as EMM386 on  
your PC, you must reserve the upper memory for the NIC.  
The 3C319 NICs default configuration requires 16 K  
of shared RAM at address D8000–DBFFF and 8 K of  
MMIO/BIOS address at CC000. The following example  
uses EMM386 and the default memory range.  
 
Running the AutoLink Program  
3-3  
1 Make a backup copy of the CONFIG.SYS file. Type:  
copy config.sys config.old [Enter]  
2 Edit the memory manager device statement in the  
CONFIG.SYS file to exclude the memory range that  
the 3C319 NIC uses.  
The statement should be similar to the following:  
DEVICE=C:\WINDOWS\EMM386.EXE NOEMS X=CC00-CDFF X=D800-DBFF  
where X stands for exclude, followed by the NICs  
memory range. See Chapter 5, “Configuring the  
NIC Manually,” for additional memory ranges.  
Refer to your operating system manual for additional  
instructions and information on using the memory  
manager.  
3 Save the CONFIG.SYS file and exit the text editor.  
4 Reboot the PC.  
Next, load the NetWare DOS ODI client driver by running  
the AutoLink program, as described in the next section.  
Running the AutoLink Program  
The AutoLink program loads the NetWare DOS ODI client  
driver and automatically configures the 3C319 NIC. To  
run the AutoLink program, follow these steps:  
1 Insert TokenDisk diskette #1 in the floppy drive  
and type:  
a: [Enter]  
2 Type:  
autolink [Enter]  
The first time you use the installation software, the 3Com  
software license appears.

INSTALLING A NETWORK  
DRIVER FOR WINDOWS 95  
4
This chapter describes how to install the NDIS 4 driver for  
the TokenLink Velocity ISA (3C319) NIC in Windows 95  
environments. The NDIS 4 driver conforms to Microsofts  
latest NDIS 4.0 miniport specification and provides the  
following features:  
DynamicAccess Class of Service  
Auto ring speed detection  
Promiscuous mode  
The 3C319 NIC NDIS 3 full MAC driver, which is  
compatible with Microsofts earlier NDIS 3.x specification,  
is available on TokenDisk diskette #1 in the \WIN95  
subdirectory. However, the features listed above are  
available only with the NDIS 4 driver.  
Explicit instructions for installing the NDIS 3 driver are  
no longer provided in this guide because that driver has  
been superseded by the NDIS 4 driver, which provides  
additional features such as DynamicAccess Class  
of Service.  
If you still want to load the NDIS 3 driver, follow the  
instructions provided in this guide for the NDIS 4 driver.  
When directed to insert TokenDisk diskette #2 (containing  
the NDIS 4 driver), you should instead insert TokenDisk  
diskette #1, which contains the NDIS 3 driver. In all other  
respects, the instructions for installing the NDIS 4 driver  
and NDIS 3 driver are nearly identical.  
 
4-2  
CHAPTER 4: INSTALLING A NETWORK DRIVER FOR WINDOWS 95  
Before Installing the Driver  
Before you install the NDIS 4 driver, make sure that the  
3C319 NIC is installed as described in Chapter 2, and that  
Windows 95 is installed.  
Have the Windows 95 software accessible on diskettes,  
CD, or hard drive in case the installation utility requests  
protocol files from the Windows 95 software library.  
If your network environment uses the TCP/IP  
communications protocol, you must obtain from your  
network administrator all the information you will need  
to define an IP address during the installation process.  
Installing the NDIS 4 Driver for Windows 95  
This section describes installing the 3C319 NIC NDIS 4  
driver for the following Microsoft Windows 95 versions:  
Retail version 950 (950a)  
OEM Service Release 2 (OSR2) version 950b  
The default installation modes are 16 Mbps ring speed  
and 3Com mode. If these options are not satisfactory,  
you can change the settings in Windows 95.  
About Microsoft Windows 95 Versions  
The 3C319 NIC NDIS 4 driver installation procedures differ  
depending on the Windows 95 version installed on  
your PC.  
Retail Version of Windows 95  
If your PC did not come with Windows 95 already  
installed, you must install the retail version of  
Windows 95 (version 950) before you load the driver.  
The retail version of Windows 95 is designed to upgrade  
Windows 3.x PCs.  
 
Installing the NDIS 4 Driver for Windows 95  
4-3  
OSR2 Version of Windows 95  
Some PCs are sold with a special Windows 95 version  
already installed. Windows 95 OEM Service Release 2  
(OSR2) is version 950b of Windows 95. An OEM Service  
Release is an updated version of a Microsoft product for  
PC original equipment manufacturers (OEMs) to preinstall  
on new PCs. The OSR2 version of Windows 95 contains  
some new hardware support and programs.  
Finding the Windows 95 Version  
To determine which Windows 95 version you are using,  
open the Control Panel, select System, and read the  
System information under the General tab. If your  
release is version 4.00.950 (or 4.00.950a), you are using  
the retail version of Windows 95 (version 950). If your  
release is version 4.00.950b, you are using the OSR2  
version of Windows 95 (version 950b).  
Installing the NDIS 4 Driver for Retail Windows 95  
This section describes two ways to install the NDIS 4  
driver for retail Windows 95 (version 950), depending on  
whether or not your PC supports PnP configuration. If  
you are not sure whether your Windows 95 version has  
PnP support, first try the following procedure, “When  
Windows 95 PnP Detects the NIC.” If your PC does not  
automatically detect the 3C319 NIC after you turn on  
power to the PC, use the second procedure, “When  
Windows 95 Does Not Detect the NIC.”  
When Windows 95 PnP Detects the NIC  
Follow these steps to install the NDIS 4 driver for  
Windows 95 with PnP support. It is assumed that you

CONFIGURING THE  
NIC MANUALLY  
5
This chapter describes how to configure the 3C319 NIC  
manually using the Configuration and Diagnostic Program  
on TokenDisk diskette #1. Use the procedures in this  
chapter if:  
Your PC does not provide PnP configuration; the BIOS  
does not have a utility that recognizes and configures  
PnP-enabled devices  
The PnP utility on your PC does not detect and  
configure the 3C319 NIC  
Your network operating system does not support  
PnP configuration  
You need to reconfigure a parameter not set by the  
PnP BIOS  
You need to disable PnP for the 3C319 NIC  
You have a system failure while using the  
Configuration and Diagnostic Program  
Change the default configuration for the NIC only if you  
have conflicts with other devices or cards. (See Table 2-1  
for initial settings set by 3Com for configuration options.)  
For standard settings of commonly used devices, refer to  
the SYSRESRC.TXT file in the HELP directory on TokenDisk  
diskette #1.  
This chapter does not apply to 3C319 NICs installed in  
EISA PCs with the AutoSwitch option enabled. To change  
software option settings in an EISA PC, use the EISA  
configuration utility provided with the PC.

CHAPTER 5: CONFIGURING THE NIC MANUALLY  
Before Using the Configuration and Diagnostic Program  
To configure the 3C319 NIC, the NIC must be already  
installed in your PC and connected to the network, as  
described in Chapter 2.  
The Configuration and Diagnostic Program is a DOS  
application that will not function properly if the 3C319  
drivers are already installed.  
The Configuration and Diagnostic Program indicates  
memory conflicts if you run it with a memory manager  
without excluding the memory range used by the  
3C319 NIC. Before you run the Configuration and  
Diagnostic Program, you must bypass the drivers and  
the /memory manager. Use a DOS diskette if you are  
running DOS 5.0 or earlier.  
If you are running Windows NT, perform a clean boot  
from the DOS partition, or boot from a DOS diskette to  
run the diagnostic program. If you use Windows 95 or  
Windows for Workgroups, exit Windows and restart the  
PC in MS-DOS mode, or boot from a floppy that has the

This option enables a PC with Plug and Play (PnP) support  
to allocate resources for the 3C319 NIC. The resources  
allocated in a PnP system include:  
I/O base address  
Interrupt request level  
BIOS/MMIO base address  
Shared RAM base address  
The default for PnP is enabled. Disable PnP to configure  
the 3C319 NIC with the Configuration and Diagnostic  
Program. For instructions, see the section “Changing  
Configuration Option Settings” earlier in this chapter.  
Configuration Mode  
This 3C319 NIC provides the following two modes  
of operation:  
3Com mode  
IBM mode  
 
5-8  
CHAPTER 5: CONFIGURING THE NIC MANUALLY  
3Com mode increases the number of available IRQ  
channels from 4 to 8 and the number of I/O base  
addresses from 2 to 31. You can install up to six 3C319  
NICs per PC. 3Com drivers are supplied on the TokenDisk  
diskettes to support these 3Com mode enhancements.  
The default is 3Com mode.  
IBM mode provides the same configuration options as  
IBM 16/4 Token Ring Adapters: 4 IRQ channels and 2 I/O  
base addresses. You can continue to use IBM drivers with  
the NIC in IBM mode.  
Ring Speed  
The 3C319 NIC operates at a ring speed of either  
4 or 16 Mbps. The 3C319 NIC ring speed must match the  
speed of the token ring network. The default value is  
16 Mbps. For the NDIS 4 driver, the auto ring speed  
detection feature is enabled by default. (To disable the  
auto ring speed detection feature, see “Auto Ring Speed  
Detection” in Chapter 7.)  
I/O Base Address  
In IBM mode when only one 3C319 NIC is installed, it is  
designated the Primary NIC. Change the Primary/Alternate  
option with the Configuration and Diagnostic Program.  
The base address allowed in IBM mode is A20h (primary)  
or A24h (alternate). The default is A20h.  
In 3Com mode the I/O base addresses designate the  
NICs. The I/O base addresses for 3Com mode are as  
follows, with the default address in bold:  
A20h

If a system resource conflict continues, you may have to  
change the settings of other NICs or options that are in  
your PC.  
BIOS/MMIO Address Location  
There are 12 possible 8 KB blocks of PC memory that can  
be assigned for accessing the ROM area of the 3C319  
NIC. The factory default ROM address for the 3C319 NIC  
is CC000–CDFFF. The ROM address locations are as  
follows, with the default in bold:  
C8000-C9FFF  
CA000–CBFFF  
CC000–CDFFF  
CE000–CFFFF  
D0000–D1FFF  
D2000–D3FFF  
D4000–D5FFF  
D6000–D7FFF  
D8000–D9FFF  
DA000–DBFFF  
DC000–DDFFF  
DE000–DFFFF  
The BIOS/MMIO address selected must not be assigned  
for use by any other NIC or device and cannot be the  
same as the RAM address for this NIC. If a system  
resource conflict exists, you may have to change the  
settings of other NICs or devices that are in your PC.  
Shared RAM Page Size and Address Range  
There are 22 possible blocks of memory available  
for accessing the RAM located on the 3C319 NIC.  
The factory default RAM size and address location  
for the 3C319 NIC, which support RAM paging, are  
16 KB / D8000–DBFFF.  
RAM paging allows the software to access all 64 KB of  
RAM on the 3C319 NIC one page (16 KB) at a time,  
while using only 16 KB of PC memory space. RAM  
paging is available for all 16 KB address ranges.  
 
5-10  
CHAPTER 5: CONFIGURING THE NIC MANUALLY  
If a conflict exists, you may have to change the settings  
of other NICs or adapters that are in your PC. The 22  
RAM address ranges are as follows, with the default  
in bold:  
8 KB / C8000–C9FFF  
8 KB / CA000–CBFFF  
8 KB / CC000–CDFFF  
8 KB / CE000–CFFFF  
8 KB / D0000–D1FFF  
8 KB / D2000–D3FFF  
8 KB / D4000–D5FFF  
8 KB / D6000–D7FFF  
8 KB / D8000–D9FFF  
8 KB / DA000–DBFFF  
8 KB / DC000–DDFFF  
8 KB / DE000–DFFFF  
16 KB / C8000–CBFFF  
16 KB / CC000–CFFFF

16 KB / D4000–D7FFF  
16 KB / D8000–DBFFF  
16 KB / DC000–DFFFF  
32 KB / C8000–CFFFF  
32 KB / D0000–D7FFF  
32 KB / D8000–DFFFF  
64 KB / D0000–DFFFF  
Interrupt Request Level  
A 3C319 NIC can operate on one of four interrupt levels  
for IBM mode (2 [9], 3, 6, or 7), or one of eight interrupt  
levels for 3Com mode (2 [9], 3, 5, 6, 7, 10, 11, or 15).  
The default interrupt level is 2, but the 3C319 NIC can  
operate on any of the levels if necessary. If a conflict  
continues, you may have to change the setting of other  
NICs or devices that are in your PC.  
Other Configuration Options  
The Configuration and Diagnostic Program also allows  
the selection of the following additional parameters.  
3Com recommends that you avoid changing these  
configuration settings.  
Memory Mode —Allows operation with 8-bit or 16-bit  
memory interfaces. The default is 16-bit, but the 8-bit  
option is provided for backward compatibility with older  
PCs. The Parallel Tasking feature is disabled in 8-bit mode.  
I/O Mode —Allows operation with 8-bit or 16-bit I/O  
interfaces. The default is 16-bit, but the 8-bit option is  
provided for backward compatibility with older PCs.  
 
Configuration Options  
5-11  
IRQ Driver Type —Provides a choice of IRQ signal drivers  
to the ISA bus. The level-sensitive type relies on the  
motherboard circuitry for reliable operation and allows  
shared interrupts. Edge triggering is a more robust  
technique because it is independent of motherboard  
circuitry, but does not allow shared interrupts. The default  
is edge-triggered.  
AutoSwitch —When enabled, allows installation of  
the 3C319 NIC in an EISA PC by the EISA configuration  
utility without running the 3TRDIAG program first. The  
default is disabled. Do not enable AutoSwitch if you  
installed the 3C319 NIC in an ISA PC.  
Boot PROM —When enabled, allows the PC to boot  
from a server. The default is disabled.  
Zero Wait State —When enabled, allows the PC to  
communicate with the 3C319 NIC more quickly. Some  
PCs may not operate correctly with this option enabled.  
The option can be disabled to solve this problem. The  
default is enabled.  
 
 
INSTALLING A NETWORK  
DRIVER FOR WINDOWS NT  
6
This chapter describes how to install the NDIS 4  
driver for the TokenLink Velocity ISA (3C319) NIC in  
Windows NT environments. The NDIS 4 driver conforms  
to Microsofts latest NDIS 4.0 miniport specification and  
provides the following features:  
DynamicAccess Class of Service  
Auto ring speed detection  
Promiscuous mode  
The 3C319 NIC NDIS 3 full MAC driver, which is  
compatible with Microsofts earlier NDIS 3.x specification,  
is available on TokenDisk diskette #1 in the \WINNT  
subdirectory. However, the features listed above are  
available only with the NDIS 4 driver.  
Explicit instructions for installing the NDIS 3 driver are  
no longer provided in this guide because that driver has  
been superseded by the NDIS 4 driver, which provides  
additional features such as DynamicAccess Class  
of Service.  
If you still want to load the NDIS 3 driver, follow the  
instructions provided in this guide for the NDIS 4 driver.  
When directed to insert TokenDisk diskette #2 (containing  
the NDIS 4 driver), you should instead insert TokenDisk  
diskette #1, which contains the NDIS 3 driver. In all other  
respects, the instructions for installing the NDIS 4 driver  
and NDIS 3 driver are nearly identical.

“Configuring DynamicAccess Class of Service.”  
 
CONFIGURING  
DYNAMICACCESS  
CLASS OF SERVICE  
7
This chapter describes enabling and configuring  
DynamicAccess Class of Service support for  
Windows 95 and Windows NT.  
The DynamicAccess Class of Service feature lets you select  
critical applications for high-priority network access.  
Class of Service prioritization allows stations running  
critical applications under Windows 95 or Windows NT  
to access network bandwidth before other stations. The  
NDIS 4 driver requests a priority token when the selected  
applications transmit data.  
DynamicAccess Class of Service is only available with the  
3C319 NIC NDIS 4 driver. This feature is not available with  
other 3C319 NIC drivers.  
The DynamicAccess Class of Service feature is disabled  
by default; if you want to take advantage of this feature,  
you must manually enable it after installing the  
NDIS 4 driver.  
Before Starting Configuration  
The 3C319 NIC must be installed and configured  
before you configure DynamicAccess Class of Service.  
For installation instructions, see Chapter 2, “Installing the  
3C319 NIC.” If your operating system does not  
automatically detect and configure the NIC, you must  
configure the NIC manually. See Chapter 5, “Configuring  
the NIC Manually,” for instructions.  
The NDIS 4 driver must also be installed before you  
configure DynamicAccess Class of Service. For installation  
instructions, see Chapter 4, “Installing a Network Driver  
for Windows 95,” or see Chapter 6, “Installing a Network  
Driver for Windows NT.”  
 
7-2  
CHAPTER 7: CONFIGURING DYNAMICACCESS CLASS OF SERVICE  
Finally, you must also have installed the appropriate  
applications that you want to prioritize.  
Activating Class of Service  
To select Class of Service applications in a Windows 95 or  
Windows NT environment, follow these steps:  
1 In the Control Panel group, double-click the  
Class of Service icon.  
The Supported Applications tab of the 3Com Class of  
Service Setup screen appears, as shown in Figure 7-1.  
Figure 7-1 3Com Class of Service Setup Screen  
2 Click Enable in the Class of Service box.  
The default mode is Disable.  
 
 
Adding Class of Service Ranges and Protocols  
7-3  
3 Click the boxes next to the appropriate  
application names for which you want to  
activate Class of Service.  
For the NDIS 4 driver to recognize high-priority network  
traffic, it must know if a stream of network traffic was  
generated by a given application.  
If an application is not listed here, you can obtain  
the necessary information from the application’s  
manufacturer and manually enter the information in  
the Additional Ranges tab.  
4 Click OK.  
Adding Class of Service Ranges and Protocols  
You can add information for Class of Service applications  
that you want to prioritize but which are not listed on  
the 3Com Class of Service Setup screen (Figure 7-1).  
You must specify port or socket ranges as well as the  
network protocol being used. Obtain the information  
from the application manufacturer. The Class of Service  
packet should be treated as high-priority.  
To add the Class of Service ranges and protocols, follow  
these steps:  
1 Click the Additional Ranges tab.  
The Class of Service Additional Ranges screen appears,  
as shown in Figure 7-2.  
c
 
7-4  
CHAPTER 7: CONFIGURING DYNAMICACCESS CLASS OF SERVICE  
Figure 7-2 Initial Class of Service Additional Ranges Screen  
2 Enter the beginning of the port or socket range for  
the application in the Range Start box.  
The range start should be a hexadecimal value with a  
maximum of four digits.  
3 Enter the inclusive range end value of the port  
or socket range for the application in the  
Range End box.  
The range end should be a hexadecimal number with a  
maximum of four digits. If only one port or socket is  
needed, Range End should match Range Start.  
4 Select the protocol that the application uses.  
This can be TCP, UDP, or IPX. Some applications support  
multiple protocols and have port or socket ranges for  
each protocol. In this case, the range or protocol must  
match the protocol on the PC.  
 
 
Using Class of Service Advanced Options  
7-5  
For example, if only TCP/IP is installed, do not enter  
the socket range for IPX, as it will adversely affect  
driver performance.  
5 Once the Range Start, Range End, and Protocol are  
entered press Add.  
The range is added to the list, as shown in Figure 7-3.  
c
Figure 7-3 Class of Service Additional Ranges Screen with  
Added Ranges  
6 Click OK when you are finished.  
To remove a range, select the range in the list and  
click Remove.  
Using Class of Service Advanced Options  
You can use Class of Service Advanced Options to  
adjust the network drivers handling of certain types of  
Class of Service traffic. In general, you do not need to  
change these values. Contact your network administrator  
before using these options.  
 
 
7-6  
CHAPTER 7: CONFIGURING DYNAMICACCESS CLASS OF SERVICE  
Accessing Class of Service Advanced Options  
To access the advanced options, follow these steps:  
1 To display the Class of Service Advanced Options  
screen, click the Advanced Options tab.  
The Class of Service Advanced Options screen appears, as  
shown in Figure 7-4.  
Figure 7-4 Class of Service Advanced Options Screen  
2 Enter new information as required.  
3 Click OK to set the new value.  
4 Reboot the system to activate changes.  
 
 
Using Class of Service Advanced Options  
This section provides a detailed description of each  
Advanced Values field shown on the Class of Service  
Advanced Options screen (Figure 7-4).  
The Advanced Options section of the Class of Service  
Advanced Options Screen shown in lower part of  
Figure 7-4 is not currently available for token ring  
installations.  
FIFO Packet Threshold  
This setting controls the number of non–Class of Service  
packets the network driver will allow in the FIFO ahead  
of any Class of Service packets. A smaller number  
decreases the time between Class of Service packets  
but can adversely affect performance. A value of 12  
is recommended.  
Concurrent UDP Streams  
This option controls the number of simultaneous  
multimedia UDP packet streams the network driver can  
handle at any time. For many applications, the number of  
UDP streams is the same as the number of connections.  
For example, for videoconferencing with three people,  
applications use three UDP streams for the video data.  
The value must be a power of two (2, 4, 8) but the  
optimal value may vary depending on the PC and  
application.  
A video server may support 32 connections, but a client  
may only want to conference with four other people at  
a time.  
A value of 16 is recommended for most applications.  
Low-Priority Ratio  
When Class of Service support is enabled, high-priority  
packets are always transmitted before low-priority  
packets. If a certain high-priority application sends out  
enough packets, no low-priority packets may be sent.  
 
7-8  
CHAPTER 7: CONFIGURING DYNAMICACCESS CLASS OF SERVICE  
To prevent this problem, the driver uses a ratio value  
to periodically send out a low-priority packet (if one is  
waiting to be sent).  
For example, if a value of 1000 is entered, one  
low-priority packet would be sent for every 1000  
high-priority packets. A value of 25 is recommended  
for most applications.  
Natural Packet Interval  
This field is not applicable for token ring installations. Any  
value entered in this field is ignored.  
Disable Switch Packet Prioritization  
This option is not currently enabled for token ring  
installations. Any setting is ignored.  
Disable Receive Packet Buffering  
This option is not currently enabled for token ring  
installations. Any setting is ignored.  
Auto Ring Speed Detection  
An alternative way to access DynamicAccess Class  
of Service is to click the Properties button with the  
3C319 NIC selected while you are viewing the adapters  
list. Using this method also allows you to disable or  
enable the auto ring speed detection option.  
The auto ring speed detection option permits the NDIS 4  
driver for Windows 95 and Windows NT to detect and  
operate at the current ring data rate. Auto ring speed  
detection is automatically enabled when you load the  
NDIS 4 driver. (This feature is not available with other  
3C319 NIC drivers.)  
To manually set the ring speed after disabling auto ring  
speed detection, see “Changing Configuration Option  
Settings” in Chapter 5.

CHAPTER 8: MANUALLY INSTALLING MISCELLANEOUS NETWORK DRIVERS  
Using IBM Drivers  
Since the 3C319 NIC is fully IBM-compatible you can use  
drivers for IBM 16/4 Token Ring Adapters.  
Obtain IBM token ring drivers for the 3C319 NIC in one  
of the following ways:  
Copy the IBM 16/4 Token Ring Adapter drivers  
supplied with your network operating system.  
Use the IBM 16/4 Token Ring Adapter drivers in IBMs  
LAN Support Program version 1.2 or later.  
With IBM drivers, use only IBM-compatible settings.  
To use the IBM 16/4 Token Ring Adapter drivers supplied  
with your network operating system, copy them to your  
PC and follow the instructions that accompany the  
network operating system.  
Using Remote Program Load (RPL)  
The Remote Program Load capability included with the  
3C319 NIC allows you to load boot images from Novell  
NetWare, IBM LAN Server, Microsoft LAN Manager, and  
Banyan VINES servers.  
If RPL is enabled on the NIC and on the network server,  
the PC can boot from a server on the token ring network  
using the configured NIC. This eliminates the need to  
use local drives or diskettes.  
RPL can be disabled to allow the PC to boot from its hard  
disk using 3Coms 3TRDIAG program. You can also use  
IBMs installation and RPL operation documentation for  
3C319 NIC procedures.  
The RPL capability can only be used with:  
I/O base addresses A20h or A24h  
Shared RAM address D8000  
 
Using Remote Program Load (RPL)  
8-9  
BIOS/MMIO address CC000  
IRQs 2, 3, 6, or 7  
RPL is not supported on the 3C319 NIC in an EISA PC  
with the AutoSwitch function enabled.  
Before Using RPL  
To use RPL, enable the boot PROM feature on the NIC  
and use the procedures that follow.  
Refer to your network operating system documentation  
for instructions on how to create a boot image that loads  
the IBM token ring driver.  
Enabling RPL  
The following procedure explains how to enable RPL.  
Refer to your network operating system documentation  
for network procedures and for information on drivers

This chapter describes how to isolate and solve  
3C319 NIC hardware and network cabling problems  
in the following sections:  
3C319 NIC LEDs  
Using the Configuration and Diagnostic Program  
Diagnostic Test Types  
Troubleshooting Tips  
3C319 NIC LEDs  
Light-emitting diodes (LEDs) on the backplate of the  
3C319 NIC, shown in Figure 9-1, indicate the configured  
ring speed and whether or not the 3C319 NIC is  
inserted into the ring. The LEDs also light when drivers  
are loading and when the diagnostics program is running.  
16 Mbps  
4 Mbps

Figure 9-1 NIC LEDs  
 
 
9-2  
CHAPTER 9: TROUBLESHOOTING NIC INSTALLATION  
When the green LED (labeled “4”) is lit, it indicates that  
the 3C319 NIC is set to 4 Mbps speed and is correctly  
inserted into the token ring network.  
When the yellow LED (labeled “16”) is lit, it indicates that  
the 3C319 NIC is set to 16 Mbps and is correctly inserted  
into the token ring network.  
Using the Configuration and Diagnostic Program  
You can run the Configuration and Diagnostic Program  
on TokenDisk diskette #1 to test the setup or  
configuration and test for physical board problems.  
The diagnostic program tests the 3C319 NIC, not the  
network. Boot from DOS before running the diagnostic  
program. Connect the 3C319 NIC to the network for all  
diagnostic tests.  
The Configuration and Diagnostic Program is a DOS  
application that does not function properly if the 3C319  
NIC drivers are already installed. The program also  
indicates memory conflicts if you run it with a memory  
manager without excluding the memory range used by  
the 3C319 NIC. You must bypass the drivers and the  
memory manager before you run the diagnostic program.  
Use a DOS diskette if you are running DOS 5.0 or earlier.  
If you are running Windows NT, boot from the DOS  
partition or boot from a DOS diskette to run the  
diagnostic program. If you use Windows 95 or Windows  
for Workgroups, exit Windows and restart the PC in  
MS-DOS mode, or boot from a floppy that has the  
operating system installed on it.  
Diagnostic Test Types  
There are two groups of Configuration and Diagnostic  
Program tests.  
A lobe cable must be connected from the 3C319 NIC to a  
retiming concentrator or MAU for all Group 1 tests. A  
lobe cable is the section of cable that attaches a ring  
station or network device to a MAU or wiring hub.  
 
Diagnostic Test Types  
9-3  
Group 1 Diagnostics  
Group 1 diagnostics test physical components,  
connectors, and circuitry of the 3C319 NIC as follows.  
MMIO Register Write/Read Test  
This test verifies that the PC can access the 3C319 NICs  
memory mapped I/O registers correctly.  
Boot PROM Test  
This test verifies that the PC can access the boot PROM  
correctly and verifies the integrity of the boot PROM.  
AIP Checksum Test  
This test verifies that the 3C319 NICs node ID, channel  
identifier, and supported function identifiers such as data  
rate, shared RAM, and transmit buffer size are correct.  
Shared RAM Boundary/Domain Test  
This test verifies that the shared RAM base address is  
aligned on the proper address boundary according to the  
shared RAM page size setting and verifies that its domain  
does not conflict with that of the 3C319 NIC ROM.  
Shared RAM Write/Read Test  
This test verifies that the PC can correctly access the total  
64 KB of available shared RAM.  
Timer Test  
This test verifies the 3C319 NICs timer operations by  
comparing the 3C319 NIC timing to the PCs timing.  
Open NIC for Ring Operation Test  
This test prepares the 3C319 NIC for a NIC ring operation  
test and verifies the 3C319 NICs ability to transmit data  
over the network. This test requires you to connect to an  
STP or a UTP cable with a DAU, MAU, CAU, or token  
ring switch at the other end.  
 
9-4  
CHAPTER 9: TROUBLESHOOTING NIC INSTALLATION  
Ring Operations Test  
This test assesses communication on the ring. The  
3C319 NIC must be attached to the ring to run this test  
successfully. The 3C319 NIC also must be set to the  
correct ring speed. Note that this test always fails when  
you are using a Dedicated Token Ring (DTR) hub.  
Close NIC Test  
This test verifies the 3C319 NICs ability to close the  
3C319 NIC and terminate the Ring Operations Test. The  
3C319 NIC must have been previously opened.  
Group 2 Diagnostic  
The Group 2 diagnostic test (NIC Wrap Test) causes all  
user-transmitted data to be sent and received without  
going to the network.  
A lobe cable must be connected from the selected  
3C319 NIC to a retiming concentrator or MAU for the  
Group 2 test. A lobe cable is the section of cable that  
attaches a ring station or network device to a MAU or  
wiring hub.  
Running the Diagnostic Tests  
The Configuration and Diagnostic Program can be  
started from the menus or the DOS command line. For  
command line instructions, see the INSTRUCT.TXT file in  
the \HELP subdirectory on TokenDisk diskette #1.

the diagnostic program.  
3 Select OK and press [Enter].  
The Run Tests Dialog box reappears (Figure 9-3).  
4 To run the tests, select Start and press [Enter].  
Troubleshooting Tips  
If a diagnostic test fails, the 3C319 NIC may not be  
defective. The problem is usually incorrect option settings  
or option settings that conflict with the settings of other  
boards, or the 3C319 NIC may be improperly installed.  
Windows NT versions 3.51 and 4.0 are not PnP-enabled  
operating systems. If the network driver fails to load  
when the 3C319 NIC is installed in a PnP PC, configure  
the NIC using the Configuration and Diagnostic Program  
on TokenDisk diskette #1. Follow the procedures in  
Chapter 5, “Configuring the NIC Manually,” to disable PnP  
for the 3C319 NIC and then configure the NIC.  
If a test fails, you can get additional information by  
highlighting the test that failed in the Run Tests dialog  
box and pressing [Enter]. You can also highlight the Zoom  
button and press [Enter]. The program notifies you of the  
error and suggests actions for solving the problem.  
CAUTION: Turn off the power before inserting or  
removing the 3C319 NIC from the PC.  
Follow these steps to isolate the problem further:  
1 Seat the 3C319 NIC firmly in the slot.  
2 Inspect all cables and connections.  
3 Make sure that the LEDs on the 3C319 NIC and the  
MAU light, or that the solenoid on the MAU engages.  
 
9-8  
CHAPTER 9: TROUBLESHOOTING NIC INSTALLATION  
4 Ensure that the settings (memory allocations,  
interrupts, etc.) for the 3C319 NIC do not conflict  
with other devices installed in the PC.  
See Table 2-1 for initial settings set by 3Com for  
configuration options. See Chapter 5, “Configuring the  
NIC Manually,” for a description of the settings.  
5 Check that the ring speed (4 or 16) matches the  
network speed.  
Select the View pull-down menu in the Configuration and  
Diagnostic Program and select NIC Information to view  
the current 3C319 NIC configuration.  
6 If you installed the 3C319 NIC correctly and still  
experience problems, review your configuration  
procedures.  
Make sure that you have properly configured your PC for  
the 3C319 NIC. Refer to Chapter 5, “Configuring the  
NIC Manually.”  
Make sure that you have installed the correct drivers for  
your network operating system. Refer to Chapters 4, 6,  
and 8.  
7 Install the 3C319 NIC in another slot and run the  
diagnostic tests again to isolate a defective slot.  
The slot may be defective. If the 3C319 NIC passes the  
tests in the second slot, contact the reseller or  
manufacturer of the PC.  
8 Install the 3C319 NIC in another functioning PC and  
run the tests again.  
Your PC may be defective. If the 3C319 NIC passes the  
tests in the second PC, contact the reseller or  
manufacturer of the first PC.  
9 Replace the failed 3C319 NIC with a working  
3C319 NIC. If the second 3C319 NIC fails, the PC  
may be defective.

GLOSSARY  
3Com mode  
A mode of operation for the 3Com TokenLink Velocity ISA  
network interface card (NIC) that provides increased  
throughput and expanded configuration options.  
CAU  
Controlled access unit.  
Class of Service  
A 3Com DynamicAccess feature that helps to optimize  
network performance by letting you prioritize your  
applications for efficient network access. High-priority  
tokens are requested when the network transmits data  
for selected applications.  
Clean boot  
A DOS boot with no memory managers or other  
programs (such as drivers) loaded in memory.  
DAU  
Dual access unit.  
Driver  
A program, usually resident in the server or workstation  
memory, that controls the network hardware (such as  
NICs or controllers) or implements the protocol stacks  
through which higher-level applications communicate  
with the network hardware.  
DTR  
Dedicated Token Ring (DTR). An IEEE standard that  
increases network performance in switched token ring  
environments. It allows data transmission using dedicated  
resources between the station and the concentrator.  
Transmissions can be either half-duplex or full-duplex.  
DynamicAccess technology  
A 3Com set of features that optimize network  
performance. (See also Class of Service.)  
 
2
GLOSSARY  
EISA  
Extended Industry Standard Architecture.  
Full-duplex  
A mode of operation in which a token ring station can  
simultaneously transmit and receive independent data  
streams. Dedicated transmissions occur between the  
station and switch; token passing no longer occurs.  
Hexadecimal  
A number system with a base of sixteen. In hexadecimal,  
the first ten digits are 0–9 and the last six digits are A–F.  
This number system is identified in this guide by a number  
or character followed by “h.”  
IBM mode  
IEEE 802.5  
A mode of operation for 3Com TokenLink Velocity ISA NICs  
with configuration options restricted to the same options  
provided by IBM 16/4 Token Ring Adapters. Either 3Com or  
IBM drivers can be used when the NIC is configured in IBM  
mode.  
The standard for the token ring access method and  
physical layer specifications developed by a subcommittee  
of the Institute for Electrical and Electronics Engineers (IEEE)  
802 committee.  
Input/Output (I/O)  
The method, medium, or device (such as a keyboard,  
monitor, oppy disk, hard disk, NIC, or printer) used to  
transfer data to a PC or from the PC back to a device or  
a network.  
ISA  
Industry Standard Architecture.  
LAN  
Local area network. A communications network within  
a limited physical area such as a building that provides  
high-speed data transmission. The basic components of a  
LAN are the boards that plug into each PC to connect it  
to the network, cabling, server hardware, and software  
for network control.  
 
GLOSSARY  
3
Lobe  
All network components in a specific area that physically  
connect to a specific MAU or wiring hub.  
Lobe cable  
The section of cable that attaches a ring station or  
network device to a MAU or wiring hub.  
MAU  
NDIS  
Multistation access unit.  
Network Driver Interface Specification. A software  
specification used in many operating systems to create  
drivers for network NICs. NDIS drivers support multiple  
protocols and multiple NICs and can be unloaded from  
memory to conserve conventional DOS RAM space.  
NDIS permits the high-level protocol components to be  
independent of the NIC by providing a standard interface.  
Windows NT and Windows 95 support NDIS 3.0 and  
NDIS 4.0.  
NET.CFG  
An ASCII file containing control information for network  
protocol elements of stations and servers for a Novell  
NetWare environment.  
Network  
NIC  
A series of nodes such as PCs, terminals, or other  
peripherals interconnected by a communications channel.  
A network interface card (NIC) is a circuit board located  
inside each PC and server on the network. It allows the  
device to listen and talk to other stations and nodes on  
the network.  
ODI  
Open Data-link Interface. A MAC-level specification  
developed by Novell and Apple Computer. Like NDIS, the  
ODI driver supports multiple protocols and NICs and can  
be unloaded from memory to conserve conventional DOS  
RAM space.

GLOSSARY  
Parallel Tasking architecture  
A proprietary technique developed and patented by 3Com  
that provides significant performance improvement by  
allowing network interchanges of data to occur in parallel.  
Plug and Play (PnP)  
A standard that defines automatic techniques for making  
PC configuration simple and straightforward. Read-only  
memory (ROM) chips with unique identification numbers  
are added to each NIC, and the NIC can then arbitrate  
conflicts with interrupts, input/output ports, and memory.  
Protocol  
A formalized set of rules that PCs use to communicate.  
Because of the complexity of communications between PCs  
and the need for different communication requirements,  
protocols have been divided into modular layers, in which  
each layer performs a specific function for an adjacent layer.  
Protocol layers  
A model for describing the hierarchical set of or levels  
of protocols in which each protocol layer obtains services  
from the layer below it and performs services for the layer  
above it.  
PROTOCOL.INI  
An ASCII file containing control information for network  
protocol elements of NDIS network stations and servers.  
Token ring  
TSR  
A network that employs a ring topology and passes  
tokens for ring access.  
Terminate and stay resident. A program that upon  
execution, loads itself (or an executable portion of itself)  
into PC working memory (RAM).  
WAN
