WARNING!
Unplug your power supply when adding or removing expansion
cards or other system components. Failure to do so may cause severe damage to
both your baseboard and expansion cards.

7.
Replace the computer system’s cover.
8.
Set up the BIOS if necessary (such as
IRQ xx Used By ISA: Yes
in PNP AND
PCI SETUP)
9.

Assigning IRQs for Expansion Cards
IMPORTANT:
PCI Slots 4 & 5 share the same IRQ.
If using PCI cards on both
slots 4 & 5, make sure that the drivers support “Share IRQ” or that one card does not
need an IRQ assignment.
