PCI Compatibility
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 program configuration:
•
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 PC’s manual
and check the PCI BIOS Set up program to be sure the PCI slot
is an enabled bus-master slot.
•
In some computers, you may be required to disable Plug-and-
Play in the BIOS Set up 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 cards
using the same settings. Refer to your PC’s manual and check
the PCI BIOS Set up program configuration options for ISA
cards.
•
Make sure the PCI slot is configured to support INTA.
•
Be sure that INTA for the slot is assigned to a free interrupt
(IRQ) number.
