Installing the Novell NetWare Server Driver
This driver is installed on a Novell NetWare server running
NetWare 4.1.
The \NWSERVER subdirectory on EtherDisk Diskette #1
contains the driver (3C90X.LAN file) and NetWare Loadable
Modules (NLMs) needed for NetWare 4.1.
The NetWare server driver can also be used on a NetWare
version 3.12 server. Contact Novell to obtain the NLM files
and for instructions for installing the driver in a 3.12
environment. The NetWare 3.11 server is not supported by
the 3C905B-TX NIC.
NetWare Version 4.1
This section describes how to install the NetWare server driver

nwserver
The installation program gathers the files and prompts you
for a NIC selection.
6 Select 3Com Fast EtherLink XL 10/100 Ethernet NIC.
7 Press Enter to continue the server installation.
Multiple NICs
To support more than one NIC in a server, edit the
AUTOEXEC.NCF file to the following format:
load C:\SERVER\3C90X.LAN PORT=<port1>
NAME=<name1> FRAME=<frametype>
load C:\SERVER\3C90X.LAN PORT=<port2>
NAME=<name2> FRAME=<frametype>
Port1 and port2 are the 3C905B-TX NIC’s PCI port addresses,
and name1 and name2 are user-specified names assigned to
distinguish the multiple NICs.
The FRAME parameter is optional. The default frame type is
Ethernet_802.2. If you want the ODI server driver to support
more than one frame type, then both the unique NAME=
and FRAME= parameters must be paired on each load
driver line. The valid frame types are Ethernet_802.2,
Ethernet_802.3, Ethernet_II, and Ethernet_SNAP.
The protocols must be bound to the specific driver
configuration using the user-assigned unique names.
The following example shows how this can be done:
load C:\SERVER\3C90X.LAN PORT=1000
FRAME=Ethernet_802.3 NAME=ADPONE
load C:\SERVER\3C90X.LAN PORT=2000
FRAME=Ethernet_II
NAME=ADPTWO
bind IPX to ADPONE
bind IPX to ADPTWO
The examples used may require other parameters to work
properly. Consult the appropriate Novell NetWare manuals
for details.

Crossover Cable Troubleshooting Tips
4-13
Crossover Cable Troubleshooting Tips
When you work with network cabling, concentrators, and
NICs from different vendors, it is possible to connect
everything and still have no communication between
file servers and workstations.
When there are several unknown variables, it is difficult to
determine which component is broken. Use these tips to
isolate the problem.
1 Determine whether your equipment complies with
the 10BASE-T or 100BASE-TX standard.
This is particularly important for concentrators (hubs or
repeaters).
2 Connect a straight-through cable from the PC to
the hub.
The hub performs an internal crossover so that the signal
can go from TD+ to RD+ and TD– to RD–. When you look
at an RJ-45 connector from the front, pin 1 is identified on
the left-hand side when the metal contacts are facing up.
3 Make sure that the TD+ and TD– wires are twisted
together, and that the RD+ and RD– wires are twisted
together. The example in Figure 4-7 shows 10BASE-T
cabling.

CHAPTER 4: TROUBLESHOOTING
Using wires from opposing pairs can cause signals to
be lost. For a 100BASE-TX cable, pins #1 and #2, and #3
and #6 must be on the same twisted strand.
Troubleshooting Hubs with Crossover Cable
When there is doubt whether a hub is performing correctly,
or if the impedance settings are in question, a crossover
cable can help you isolate the failing component.
1 Connect a file server and a client PC back to back with
a crossover cable to verify that the NIC and network
operating system are properly configured.
2 To make a crossover cable, simply connect TD+ to RD+
and TD– to RD–.
The cable performs the crossover that is usually performed
by the hub. Make sure that two twisted-pair wires are
used. Figure 4-7 shows the pinouts for the crossover cable.
On the straight-through cable, make sure that the wires are
from the same twisted pair.
If the file server and client PC function together as a small
network, then either the existing cabling or the hub is the
problem.
■
If there is a proper crossover, the appropriate LED
comes on.
■
If there is a straight-through connection, the LED does
not light.
■
A blinking LED indicates that there is a polarity mismatch
(that is, TD+ to RD– instead of TD+ to RD+).

Frequently Asked Questions
4-15
Frequently Asked Questions
Table 4-2 describes some common questions and answers
about the 3C905B-TX NIC.
Table 4-2 Frequently Asked Questions
Question
Answer
Which PCI slot is best for my
PCI NIC?
3Com PCI NICs are designed to work in any bus
mastering PCI slot, preferably slot 1. Avoid any
PCI slot next to an ISA slot. This is often a shared
slot and does not support bus mastering.The
NICs perform best in those slots that support bus
mastering data transfers. Refer to your PC
manual for information on which slots support
bus mastering data transfers.
Do I have to configure the
3C905B-TX NIC?
PCI is a self-configuring bus architecture. Most of
the time you only need to install the board in your
PC; PCI does the rest. However, on some PCI
computers, you may be required to configure the
computer’s BIOS manually after installing your PCI
NIC. Refer to the owner’s guide for your PC.
What interrupts should I avoid?
You should avoid using any interrupts used by
ISA/EISA boards that do not properly support
shared interrupts (level-triggered).
If you do not know or are unsure whether other
devices or adapters in your PC support shared
interrupts, then avoid using them.
Avoid using the same interrupt as your local hard
drive (normally IRQ 14 for IDE drives and IRQ 11
for most SCSI host adapters), since not all hard
drives support shared interrupts at this time.
Avoid using 9 because it cascades with 2.
For Novell NetWare servers, avoid using IRQ 7 or
15. These IRQs only support nonshared devices
and may cause problems if they are shared
between two devices.

from your PC.
Does the 3C905B-TX NIC
support full-duplex?
Yes, the 3C905B-TX NIC supports full-duplex at
10 Mbps and 100 Mbps operation.
Why does the 3C905B-TX NIC
install as a “Generic PCI Ethernet
Controller” under Other Devices
in the Device Manager?
When Windows 95 is installed with the
3C905B-TX NIC already installed, Windows 95

Question
Answer
What should I do if a yellow
exclamation point appears next
to the 3C905B-TX NIC name?
1 In the Device Manager, double-click
Other Devices.
2 Click PCI Ethernet Controller or the duplicate
3C905B-TX NIC entry.
3 Click Remove.
4 Restart your PC.
What is the hardware IP header
checksum?
The header checksum is a field in the IP header.
When the 3C905B-TX NIC receives IP data, it
computes the IP header checksum, and if an error
occurred, the packet is dropped and is not passed
to the protocol stack. By computing the CRC
through hardware, the NIC can increase the
performance of IP traffic and reduce CPU
processing required by the protocol stack.
To avoid having the CRC computed twice (once
in the hardware and again in the software by the
protocol stack), make sure that your IP protocol
does not compute the CRC or if it does, disable
that function.
Does the 3C905B-TX NIC support The 3C905B-TX does not support NetWare
NetWare versions 3.11 or 4.0x?
versions 3.11 or 4.0x. These versions require the
use of a server driver that conforms to the
HSM 3.2 specification. 3Com no longer develops
NetWare server drivers to the HSM 3.2
specification.
What does Remote Wake-Up do? Remote Wake-Up powers up a PC remotely from
standby or suspend mode using a wake-up packet
that is sent through the LAN. With this method,
no one has to be at the PC to turn it on.
Remote Wake-Up is also known as Wake on LAN.
How can I tell if my PC supports
Remote Wake-Up?
Check to see if there is a 3-pin header for the
Remote Wake-Up connector located on the PC
motherboard and if your PC has a BIOS that
supports wake-up events based on LAN events.
If you are unsure, contact your PC vendor for
further details.
What can wake up the
3C905B-TX NIC?
The NIC can be awakened by a Magic Packet
wake-up packet sent by management software,
or by connecting or disconnecting the TP cable.

CHAPTER 4: TROUBLESHOOTING
Table 4-2 Frequently Asked Questions (continued)
Question
Answer
What is a Magic Packet?
A Magic Packet is a valid Ethernet packet that
contains a synchronization stream immediately
followed by 16 repetitions of the destination MAC
address. This Magic Packet is not protocol-specific
as long as the protocol contains the sync stream
and the 16 repetitions. This Magic Packet can be
routed in order to wake up a remote PC. Since it is
a valid Ethernet address, the Remote Wake-Up
NIC can accept broadcast or multicast packets.
What is a cable
connect/disconnect?
The NIC can also be awakened by connecting or
disconnecting the network cable.
What is Fast IP?
Fast IP is software that improves performance on
switched networks. Fast IP allows end systems
(desktops and servers) to discover switched
communication paths. By creating switched
shortcuts, Fast IP allows end stations to bypass
the router and transfer data across wire-speed
switched paths. Fast IP is part of 3Com’s
DynamicAccess software, an advanced network
driver that brings intelligence to end systems to
provide improved network performance and
control.
What are the PC and network
requirements to run Fast IP?
Client requirements:
PC running Windows 95 or Windows NT
(versions 4 or 3.51), 3Com 3C905B-TX NIC,
and the TCP/IP stack
Network requirements:
Switched path between stations and single
broadcast domain
What are the network
configuration requirements for
Fast IP?
Fast IP is designed to bypass the router,
particularly where the router is a bottleneck, as
well as to leverage the switched infrastructure.
For Fast IP to create shortcuts around routers,
there must be a switched path between source
and destination.
What is the performance gain
when using Fast IP?
Fast IP bypasses the router to provide increased
performance in switched networks even if only a
small number of network nodes use Fast IP.
The performance gain obtained when deploying
Fast IP is directly related to traffic load on the
backbone router. The more traffic pumped to
the router, the greater the latency and response
time and the higher the performance gain.
Internal tests show performance increases on the
order of 600% when routers are loaded at 70
to 75%.

Full-duplex at 100 Mbps improves the performance of
switch (hub) connections. The 3C905B-TX NIC supports
full-duplex at 10 or 100 Mbps. If the switch supports the
NWay feature and full-duplex, the 3C905B-TX NIC
automatically runs in full-duplex.
