INTRODUCTION

The 3Com® TokenLink® Velocity™ ISA 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

3Com’s DynamicAccess™ features 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 industry’s 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

■ AutoLink

16-bit client drivers

■ Universal boot PROM for booting your computer

remotely from a network server

■ Diagnostic programs to aid problem solving

™

software for easy installation of NetWare

■ 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

386 Server)

■ Windows NT version 3.51 or later

■ Windows 95

■ Windows for Workgroups

■ IBM OS/2 version 2.0 or later (IBM LAN Server)

1-4 CHAPTER 1: INTRODUCTION

■ OS/2 version 1.x or later (Novell NetWare

OS/2 Requester)

■ IBM OS/2 EE version 1.1 or later (IBM LAN

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.

INSTALLING THE

3C319 NIC

This chapter describes how to install the TokenLink Velocity ISA NIC (Part No. 3C319) in an ISA or EISA PC and how to connect the PC to the network.

CAUTION: The NIC is packed in an antistatic container to protect it during shipment. To avoid damaging highly static-sensitive components on the NIC or in the PC, reduce static electricity on your body by wearing an electrostatic discharge wrist strap attached to the chassis or by touching the chassis before handling the NIC.

1 Remove the 3C319 NIC from its box and set it on a

nonstatic surface.

2 Return all packing materials to the shipping

container.

If it is necessary to return the 3C319 NIC to 3Com, pack it in the original (or equivalent) packing material to maintain the warranty.

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.

Inserting the 3C319 NIC 2-3

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.

If you require other settings, you must change them manually, as described in Chapter 5, “Conﬁguring the

NIC Manually,” and then reboot.

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.

2-6 CHAPTER 2: INSTALLING THE 3C319 NIC

■ If you installed the 3C319 NIC in a PC running

Windows 95 with PnP, it will be conﬁgured automatically when you install the driver. See

Chapter 4, “Installing a Network Driver for Windows 95.”

After installing the NDIS 4 driver for Windows 95, you have the option to enable DynamicAccess Class of Service support for the 3C319 NIC. See Chapter 7,

“Conﬁguring DynamicAccess Class of Service.”

■ If you installed the 3C319 NIC in a PC running

Windows NT, disable PnP before installing the driver. See Chapter 5, “Conﬁguring the NIC Manually,” for instructions on disabling PnP. For Windows NT driver installation instructions, see Chapter 6, “Installing a

Network Driver for Windows NT.”

After installing the NDIS 4 driver for Windows NT, you have the option to enable DynamicAccess Class of Service support for the 3C319 NIC. See Chapter 7,

“Conﬁguring DynamicAccess Class of Service.”

■ If you installed the 3C319 NIC in a PC running

Windows for Workgroups with PnP, disable PnP before installing the driver. See Chapter 5, “Conﬁguring the

NIC Manually,” for instructions on disabling PnP.

For Windows for Workgroups driver installation information, see “Installing a Driver for Windows for

Workgroups” in Chapter 8.

■ If you installed the 3C319 NIC in a PC without PnP, or

installed the NIC in a PC with a BIOS that does not have a utility to recognize and conﬁgure PnP-enabled devices, you must manually conﬁgure the NIC before installing the driver. See Chapter 5, “Conﬁguring the

NIC Manually,” and then see Chapter 8, “Manually Installing Miscellaneous Network Drivers.”

INSTALLING NETWARE

DOS CLIENTS AUTOMATICALLY

The 3Com AutoLink software utility automatically conﬁgures one 3C319 NIC and installs the DOS 16-bit ODI client network driver for NetWare 3.12 and 4.10 systems. This chapter describes running the AutoLink program. Disregard this chapter if you do not want to install the DOS 16-bit client driver for NetWare.

AutoLink Software Functions

AutoLink software conﬁgures your PC as a NetWare DOS ODI client. The AutoLink conﬁguration program performs the following functions:

■ Conﬁgures a single 3C319 NIC.

The AutoLink conﬁguration utility cannot be used to conﬁgure multiple 3C319 NICs.

■ Installs the NetWare client software from TokenDisk

diskette #1.

■ Modiﬁes the CONFIG.SYS, AUTOEXEC.BAT, and

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 NIC’s 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.
