Selecting IRQs for cards
The table below lists the interrupts available on the
motherboard and their default functions. The notes explain
whether the default function can be disabled, if so how, and
under what circumstances it is safe to do so.
Interrupts Default Notes
Function
IRQ5, IRQ9 Not used These interrupts are not used by
IRQ10, IRQ11 the motherboard and are available
for expansion cards.
IRQ7 Parallel port IRQ7 is not normally used, and can
be used by expansion cards without

software to enable the parallel

If you are not using the parallel port
it can be disabled using SETUP,
freeing IRQ7 to be used by an
expansion card.

interface secondary IDE interface is disabled,
or not fitted.

are certain that you will not be
using it.
