edge-connector is aligned with the slot, press firmly on the top of
the board to seat it. Secure it with the screw you removed in

2.2.4.1 Assigning an IRQ for an Expansion Card
If your expansion card need an IRQ, make sure to assign an IRQ
that has not been used yet. Refer to the expansion card manual to
determine whether an IRQ is needed.
The system has a total of 16 IRQs but most of them have been
used by different components on the system leaving only 6 free
IRQs available for expansion cards.
There are 2 types of ISA cards: Legacy (configured manually using
jumpers) and PnP (IRQs are assigned automatically). When both
types of cards exist, assign an IRQ for the Legacy cards first. The
PnP card will then automatically be assigned an IRQ that has not
been used by the Legacy cards.
After all ISA cards have been assigned an IRQ, the PCI cards will
then be automatically assigned an IRQ.
Refer to the " Resources Controlled By" field in the PNP/PCI
Configuration setup of the Award BIOS for more information.
