158 Appendix C: BIOS reference
The following is a list that details what these interrupts are
assigned to by default:
Interrupt line Default device
IRQ3
IRQ4
IRQ5
IRQ7
IRQ9
IRQ10
IRQ11
An interrupt (IRQ) line that is assigned to the auxiliary I/Os
cannot be used by other devices in the unit. In other words,
changing the Aux I/O IRQ setting to an IRQ line from the list
will prevent the use of the default device associated with the
selected IRQ line.
