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.
