I thought the default irq was 2. 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??? -- ------------------------------------------------------------------------------ Michael L.
