Troubleshooting Tips
Configuring the BIOS
Your system BIOS may determine available NIC resources and
configure the Adaptec PCI NICs automatically. However,
depending on your system, you may need to configure the PCI
BIOS. To do this, enter your computer BIOS Setup and select
Advanced Settings
from the Main Menu. Make sure the following
settings are made (your BIOS may not match the following options
exactly):
Driver fails to load or
fails to recognize the
DuraLAN NIC
Check the BIOS settings. Sometimes the bus
master is disabled by default; if this is the
case, enable the bus master.
Persistent problems
with an adapter card set
to IRQ 15
This occurs in Novell’s NetWare. Either
disable IRQ 15 or change the Adaptec
DuraLAN NIC to another interrupt. Please
refer to your Novell documentation.
System hangs at boot up
Make sure the DuraLAN NIC is seated
properly in the PCI slot. Check with your
system vendor for the latest BIOS.

and so on) to PCI Interrupt Vector A.
PCI INTA-B
For the 6x022, assign an interrupt (10,11, 12, and
so on) to PCI Interrupt Vector A or B.
PCI INTA-D
