PCI Compatibility

•Older 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.

•

Make sure the PCI slot is configured to support INTA.

Ensure that INTA for the slot is assigned to a free interrupt (IRQ) number.

•Check the BIOS setup program’s PCI parameters for the slot where the network card is installed. Ensure that 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
	supplies 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.
