This works, but if I remember correctly it does take up an additional IRQ. One
of the reasons I went to an Epson USB printer...

If memory serves, IRQ 7 is typically used in PC systems for the printer. I think my old, unused, ISA Sound Blaster AWE32 would allow you to select IRQ 7, but I can't remember any other cards I've used allowing me that option.


From what I've been reading on the Linux Audio Users Group, IRQ 10 is a much better choice for a sound card. IRQ 7 has the lowest priority of all of the IRQ's. Here's the order of interrupt priority, from Highest Priority to Lowest Priority:

(highest) 0, 1, 8, 9, 10, 11 12, 13, 14, 15, 3, 4, 5, 6, 7 (lowest)

So using a printer on IRQ 7 seems quite reasonable to me. What else would one use it for?

Note: 0 and 1 are for block devices, 8 is for the Real Time Clock. 9 is the first IRQ you could try for, but it's sometimes used as a redirected IRQ 2; so I leave it alone. IRQ 10 is really the first high priority IRQ you can expect to get exclusive access to.
