- I'm glad to hear about IRQ7 and the printer. I dont know what hard drives
- use IRQ5, but I am able to use IRQ5, IRQ2(/9), IRQ4 and IRQ3 for com ports,
- and IRQ7 or printers.
-
- Mind you I'm still getting the bugs out of all this, but it is slowly coming
- along.
-
- Do you have any more info about IRQ5?
