ROUBLESHOOTING
Make sure your BIOS correctly supports the PCI Local
Bus Specification v2.0 or later and upgrade your
computer BIOS to the latest version.
Verify that the PCI slot is an enabled bus-master slot
and not a slave PCI slot. In some computers, the PCI
slot must be configured to enable bus mastering. Refer
to your computer's manual and check the PCI BIOS
Setup program to be sure the PCI slot is an enabled
bus-master slot.
In some computers, you may be required to disable
Plug-n-Play (PnP) in the BIOS Setup program if resources
are not properly assigned between installed cards.
Some computers may require you to reserve interrupts
and memory addresses for installed ISA cards to prevent
PCI adapters from using the same settings. Refer to
your computer's manual and check the PCI BIOS Setup
program configuration options for ISA cards.
