158 Appendix C: BIOS reference
The following is a list that details what these interrupts are
assigned to by default:
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.
Interrupt line Default device
IRQ3 COM2 Port
IRQ4 COM1 Port
IRQ5 Audio
IRQ7 LPT1 Port
IRQ9 Matrox Meteor-II PC-104/Plus
IRQ10 LAN Controller
IRQ11 IEEE1394
