-
- 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 manually
- configure your system, refer to your system's owner's guide.
- In addition, we have provided some hints on how you might go
- about doing this at the end of this document.
- For example, we have seen during our testing the AST Premmia
- GX P90 seem 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. In those slots
- that support busmastering data transfers, 3Com's PCI
- adapters will be able to reach their full performance
- potential. Refer to your owner's manual for information on
- which slots support busmastering data transfers.
-
- Q: Which PCI slot(s) are "Busmastering" in my PCI machine?
- A: Generally, if you have 3 PCI slots in a system, 1 of them
- will be designated as a "slave-only" slot (i.e., does not
- support bus-mastering data transfers). In some systems, all
- busmastering support may be disabled by default and will
- need to be enabled via your system's configuration utilities
- (either ROM based or some disk based utility). In
- addition, some systems have slots that physically only
- support "slave-only" PCI devices. We have found they are
- not always marked clearly to distinguish between slave-only
- and busmastering slots. It is best to refer to your owner's
- manual or contact your system manufacturer for this
- information. Also, it is also best to contact your system
- manufacturer and make sure that you have the latest version
- of the 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 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 its manufacturer for a shared interrupt driver or
- try running the systems Setup program to assign it 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 don not know, or are unsure, if 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), as not
- all hard drives support shared interrupts at this time.
- For Novell Netware Servers v4.02, you should also avoid
- using IRQ 7 or 15. These IRS only support non-shared
- devices and may cause problems if they are shared between
- two devices.
-
- Q: Is my 3Com PCI adapter a 3.3V or 5V adapter?
- A: The currently shipping 3Com adapter is a 5V adapter. It
- will not fit in a 3.3V slot.
-
- Q: My Autolink does not work with my 3Install Account on a
- Netware 4.X Server. Why?
- A: If you don't have a memory manager installed, you will
- need to have at least 576k 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 are more
- current then the files on the server volume, they will be
- used to update your system, instead of the 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 system's ROM BIOSs. If you are
- using EMM386 version 4.48 or earlier, make sure you run your
- EtherDisk Installer to allow you to replace your current
- EMM386 with an updated version from Microsoft.
-
- 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/10Base-2 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
- (Netware 4.0x Server driver and MS-DOS ODI client) are
- Novell tested and approved using Novell Netware 4.02 on
- Intel x86.

-
- On page 3-7 of the Fast EtherLink Parallel Tasking PCI
- 10/100BASE-T Network Adapter User Guide and on Page 3-8 of
- the EtherLink III Parallel Tasking PCI Bus Master Network
- Adapters User Guide, in the "Multiple PCI Adapters in a
- Client" section, beginning with the seventh paragraph, the
- text should read:
-
- "If you are running an ODI driver with multiple adapters
- already installed, specify which adapter you want the driver
- to recognize by adding the I/O base address to the NET.CFG
- file using the PCISLOT=X parameter. The 3C59X EtherDisk
- diskette contains a sample NET.CFG file in the
- /NETWARE/CLIENT directory."

- 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 on how to do this.
- 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. Make sure 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:

- 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 Phoenix BIOSs.
-
- 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 Value to be Set to
- ----------- ------------------
- Paramater
- 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.
