SMC Networks SMC2602W - Manual (Page 24)

9 | Troubleshooting
PCI Compatibility
• Early PCI BIOS versions do not properly support the new PCI specifications and may
“hang” when a network card driver tries to load. If this occurs, make sure your BIOS
correctly supports the PCI Local Bus Specification (v2.0 or later) and upgrade your
computer BIOS to the latest version
• Some PCI computers are not self-configuring and require you to perform some or all of
the following functions by motherboard jumper changes and/or BIOS Setup
configuration:
o Verify that the PCI slot is an enabled bus-master slot and not a slave PCI slot.
The SMC2602W must be installed in a PCI bus-master slot. In some computers
the PCI slot must be configured to enable bus mastering. Refer to your PC’s
manual and check the PCI BIOS Setup program to be sure the PCI slot is an
enabled bus-master slot.
o Make sure that your motherboard supports 3.3V PCI cards.
o In some computers, you may be required to disable Plug-and-Play in the BIOS
Setup program if resources are not properly assigned between the network card
and other installed cards.
o Some computers may require you to reserve interrupts and memory addresses
for installed ISA cards to prevent PCI cards from using the same settings. Refer
to your PC’s manual and check the PCI BIOS Setup program configuration
options for ISA cards.
o Make sure the PCI slot is configured to support INTA.
o Ensure that INTA for the slot is assigned to a free interrupt (IRQ) number.
Common Installation Problems
Problems are often caused by cabling errors, conflicts with other devices installed in the same
computer, or software that has been configured incorrectly. If you encounter a problem with the
SMC2602W, use the following checklists to identify and correct the problem.
• If you’re computer cannot find the SMC2602W, or the network driver does not install
correctly, check the following items before contacting SMC Technical Support
o Make sure the card is securely seated in the PCI slot. Check for any hardware
problems, such as physical damage to the card’s edge connector.
o Try the card in another PCI bus-master slot. If this fails, test the card in a
completely different system or try using a second SMC2602W in that particular
bus-master slot.
o Check for resource conflicts in the PCI configuration.
o Make sure your computer is using the latest BIOS available. Contact the
manufacturer of the computer or motherboard for information on updating the
BIOS (e.g. – Dell, Toshiba, etc)
o If there are other network cards in the computer, they may be causing conflicts.
Remove all other cards from the computer and test the SMC2602W separately. If
you continue to have problems, remove all cards except the SMC2602W and your
video card.
