Troubleshooting

•
Check the BIOS Setup program’s PCI parameters for the slot
where the 3Com OfficeConnect 10/100 NIC is installed. Be sure
the slot is configured for level-triggered interrupts instead of
edge-triggered interrupts. An example of typical PCI parameters
follows:
PCI Slot #:
(slot number where the network card
is installed)
Master:
Enabled
Slave:
Enabled
Latency Timer:
40(range is 20 to 255)
Interrupt Type:
Level-Triggered
Interrupt Number:
choose any number the BIOS Setup
provides that does not conflict
with another installed card)
Note:
The wording of these parameters varies with different
computers, and not all parameters may be configurable.
Always consult your computer manual for information on changing
motherboard jumper settings and BIOS Setup program
parameters for use with PCI network cards. If you set a
motherboard jumper and modify the computer’s BIOS Setup,
make sure the jumper and BIOS settings match.
Adapter Installation Problems
If your computer cannot find the 3Com OfficeConnect 10/100 NIC
or the network driver does not install correctly, check the following:
•
Make sure the adapter is securely seated in the PCI slot. Check
for any hardware problems, such as physical damage to the
card’s edge connector.
•
Try the card in another PCI bus-master slot. If this fails, test with
another 3Com OfficeConnect 10/100 NIC that is known to
operate correctly.
•
Check for resource conflict in the PCI configuration. See
“PCI Compatibility.”
•
Make sure your computer is using the latest BIOS available.
•
If there are other network adapters in the computer, they may be
causing conflict. Remove all other adapters from the computer
and test the 3Com adapter separately.
•
Check for a defective computer or PCI bus by trying the adapter
in another computer that is known to operate correctly.
