FREQUENTLY ASKED QUESTIONS AND RELEASE NOTES

This file contains the release notes and answers to some frequently asked
questions about the PCI and EISA environments to help you get the most out
of your 3Com Fast EtherLink/EtherLink III PCI and EISA adapters. This
information is updated regularly on 3Com's CompuServe forum (Ask3Com) and on
the 3Com BBS (bulletin board service).


FREQUENTLY ASKED QUESTIONS

Q: Do I have to configure my 3Com PCI adapter for my computer?
A: PCI is a self-configuring bus architecture. Most of the time you will
not need to do anything except install the board in your system; PCI then
takes over from there and does the rest. However, on some PCI computers
(mostly with PCI-ISA/EISA combination buses in the same machine), you may
be required to manually configure the computer's BIOS after installing your
PCI adapter. If you need to configure your system manually, refer to the
owner's guide for your system. In addition, at the end of this document we
have provided some hints on how you might go about doing this. For example,
we have seen during our testing that the AST Premmia GX P90 seems to require
you to run the EISA configuration utility once you install the board to make
sure that the I/O base address of the device does not conflict with other
devices in the system.

Q: Which PCI slot is best for my 3Com PCI adapter?
A: 3Com PCI adapters are designed to work in any PCI slot in the system,
including "slave-only" slots. 3Com's PCI adapters will reach their full
performance potential in those slots that support bus mastering data
transfers. Refer to your owner's manual for information on which slots
support bus mastering data transfers.

Q: Which PCI slot(s) are "bus mastering" in my PCI machine?
A: Generally, if you have three PCI slots in a system, one slot will be
designated as a "slave-only" slot (i.e., it does not support bus-mastering
data transfers). We have found slots are not always marked clearly to
distinguish between slave-only and bus mastering slots. It is best to refer
to your owner's manual or contact your system manufacturer for this
information. Also, it is best to contact your system manufacturer and make
sure that you have the latest version of your system's BIOS. At the end of
this document we have included some phone numbers for leading PCI system
manufacturers.

Q: Which interrupt should I use with my 3Com PCI adapter?
A: Unless your system is a PCI-ISA/EISA combination computer that requires
manual configuration, you should not have to worry about setting interrupts.
However, if your computer is not self-configuring, you will need to set
your PCI adapter's interrupts manually. To do this, you may need to set a
jumper on your motherboard and/or set the interrupt in the system's BIOS.
In either case, you will need to assign the PCI interrupt (INTA) to any
available interrupt not being used by an ISA or EISA add-in board already
in your system. Keep in mind that the interrupt configuration on your
computer's motherboard and in your BIOS must match each other. Since PCI
supports shared interrupts, multiple 3Com PCI adapters can use the same PCI
interrupt in the system (except as noted below).

Q. Does my PCI adapter support shared interrupts?
A. The drivers for the Fast EtherLink/EtherLink III PCI adapter support
shared interrupts. However, because there is no industry-standard way to
support shared interrupts, other adapters may support them differently, or
not at all. If you have another PCI adapter that does not support shared
interrupts (for example, a SCSI host adapter), either contact the
manufacturer for a shared interrupt driver or try running the system setup
program to assign it a different interrupt.

Q: What interrupt should I avoid using with my 3Com PCI adapter?
A: 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 your adapter supports shared interrupts, then it
is best to avoid using them. In addition, you should try to 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. For Novell NetWare servers, you should also avoid
using IRQ 7 or 15. These IRQs only support non-shared devices and may
cause problems if they are shared between two devices.

Q: Is my 3Com PCI adapter a 3.3 V or 5 V adapter?
A: The 3Com adapter currently being shipped is a 5 V adapter. It will not
fit in a 3.3 V slot.

Q: My AutoLink does not work with my 3Install Account on a NetWare 4.X
server. Why?
A: If you do not have a memory manager installed, you will need
at least 576 K of conventional memory to connect to a NetWare 4.X server
3Install volume with AutoLink. Some of the possible errors returned during
AutoLink that may indicate you are running low on memory are as follows:
"Login-4.084-100: Access has been denied."
"Login-4.084-903: The command Line Syntax is Invalid. For help type Login /?"
"Login-4.084-971: The workstation does not have enough memory to load the
unicode table file"
"Login-4.084-240: This utility was unable to open script file xxxx. Error
executing the program update; No such file or directory."

Q: When I run my AutoLink and connect to a 3Install volume, not all the
files from the 3Install volume are copied to my system. Why?
A: When AutoLink connects to a 3Install volume on a NetWare server, upon
completion, it will indicate that your system has been updated from the
3Install server volume. What is not stated here is that when files on the
EtherDisk diskette are more current than the files on the server volume, the
EtherDisk files will be used to update your system, instead of the files
from the 3Install volume.

Q: My 3Com PCI adapter driver will not load when EMM386.EXE is loaded. Why?
A: Microsoft's EMM386.EXE versions 4.48 and earlier may conflict with some
PCI systems’ ROM BIOS. If you are using EMM386 version 4.48 or earlier,
make sure you run your EtherDisk diskette Installer that allows you to
replace your current EMM386 with an updated version.

Q: The adapter works fine in DOS, but I can't execute programs loaded over
the net when Windows is running. What's wrong?
A: If the EMM386.EXE memory manager is not loaded by your CONFIG.SYS file,
Windows loads an equivalent driver when Windows is started. The problem is
that the EMM386 Windows emulator that ships with Windows 3.1 and Windows for
Workgroups 3.11 is not compatible with PCI computers. To solve this problem,
put the statement

DEVICE=C:\DOS\EMM386.EXE NOEMS

immediately following the line

DEVICE=C:\DOS\HIMEM.SYS

in your CONFIG.SYS file. Make sure you are running version 4.49 or newer. If
you are not sure which version of EMM386 you have, run EMM386UP.BAT on the
EtherDisk diskette. This program will update EMM386 if the update is needed.

Q: If my hub port is set up for full duplex operation, should I still use
my 3Com PCI adapter in half duplex mode?
A: No. If a port on the hub is configured full duplex, then the port on the
workstation MUST be configured to match. (Note: Full Duplex operation is
only supported when running in 10BASE-T/10BASE2 modes).

Q: My ACERPOWER system indicates that I have a ROM installed, but one is not
present. Why?
A: The BIOS ACERPOWER (BIOS version V2.0 486/DX2 66 MHz) PCI system
incorrectly indicates (via the PCI information) that there is a ROM on the
adapter on the PCI adapter. Contact ACER to get an updated BIOS to correct
this problem.

Q: Are my Fast EtherLink/EtherLink III PCI ODI drivers "Novell Certified"?
A: Yes. 3Com's Fast EtherLink/EtherLink III PCI ODI drivers are Novell
tested and approved.

to:

Bus mastering is not supported in some EISA slots in all computers.

A Short Cut to Finding the Port Address

Once you know the slot number of an adapter, you can determine its port
address as follows:

Multiply the slot number by 1000 hex.
For example: 3 x 1000 hex = 3000 hex


3COM PCI ADAPTER INSTALLATION HINTS

Installing a PCI adapter in a PCI slot:
1. Put the adapter in the computer. Refer to your system documentation.

2. Start the computer. In most cases, the PCI computer will automatically
configure the adapter. If this does not happen, you may need to configure
the computer to work with the adapter. See the next section for more
details on how to do this.

If you have problems during installation:
3Com has found that some PCI computers require additional configuration
steps in order to install a PCI adapter. The steps we recommend are as
follows:

1. Determine if you have the latest BIOS version for your computer.
Contact your computer's manufacturer to make sure you are using the latest
BIOS. Here are the phone numbers for some PCI system manufacturers:

their respective owners.

2. Make sure the BIOS is set up correctly. In some PCI computers, you may
need to enable the PCI slot using the BIOS Setup program. This is especially
common in PCI computers with a Phoenix BIOS.

After installing the adapter, turn on the computer and enter the Setup
program during system initialization (usually by pressing F1, F2, or
Ctrl-Alt-S). The correct key to press is usually shown on the screen.
Once in Setup, find the entry for PCI slots (it may be in the main menu,
or sometimes in advanced system configuration) and set these parameters to:

BIOS System Setting
Parameter

PCI Slot Number Slot where the 3Com PCI adapter is installed (1-3)
Master ENABLED
Slave ENABLED
Latency Timer 40
Interrupt Choose any one of several available interrupts that
Setup provides.
Edge or Level Level Triggered Interrupt

NOTE: The exact wording of each of the parameters will vary from computer
to computer. Save the changes, exit the Setup program, and continue with the
installation.
