Something you should check is weither the bios has this IRQ reserved or
not. This is particularly a problem with bios that support Plug-n-Play.
Go into the bios and mark the IRQ as 'reserved' or 'legacy' so that the
bios won't try and use it for PNP devices. Also, be aware of the base
addresses that other cards use. If possible, bring linux up and cat
/proc/ioports and /proc/interrupts. This will show you what linux thinks
the current system is using for IRQ and base addresses.
If nothing else, take some paper and write out all the cards you have
and their IRQs and base addresses. Also, write down the ones used for
built in and assumed interrupts: Video, Disk (floppy & hard disk
controllers), serial and parallel devices, possible builtin mouse. A
good Hardware reference for the PC will list these and more.
I have a AHA1520 in one box using IRA 11, base 0x340 and DRQ/DACK 6,
with the ROM bios at DC000. Works like a charm.

I find that this is typically just as much effort as getting it to work
under Linux (some times it's even *more* work, like in the case of Windows
NT!)
