Bear in mind that IRQ 12 is the default IRQ for a PS/2 mouse, so if you have one of those you should probably pick a different IRQ. Here is a list of IRQs and their default assignments: IRQ 1 - [used by system] IRQ 2 - Cascade Interrupt - see IRQ 9 IRQ 3 - Serial 2/COM2 IRQ 4 - Serial 1/COM1 IRQ 5 - open/expansion card IRQ 6 - floppy controller IRQ 7 - Parallel port IRQ 8 - [used by system] IRQ 9 - Cascade from IRQ 2, often usable IRQ 10 - open/expansion card IRQ 11 - open/expansion card IRQ 12 - PS/2 mouse IRQ 13 - [used by system] IRQ 14 - IDE port 1 IRQ 15 - IDE port 2 If you're short IRQ's but have serial or parallel ports you don't need, you can often disable those and use their IRQ. (unless you have one of those motherboards that doesn't fully disable something when you turn it off in the BIOS) Phil -- Philip J.
