- Once again: IRQ 2 is _unavailable_ in an AT. As you noted IRQ 2 is
- mapped to IRQ 9. This is because the AT has two interrupt
- controllers, not one like the XT did. The second chip chains off the
- first and is connected to the first through IRQ 2. Your card,
- intelligently, reassigns IRQ 2 requests to IRQ 9 if it's put into an
- AT.

- Is this a FAQ yet???
