One a 386-33 machine, the IRQs are setup as the following:
  IRQ1 Keyboard (I think)
  IRQ2 [Cascade]
  IRQ3 COM1
  IRQ4 COM2
  IRQ5 Mouse (bus)
  IRQ6 (can't remember)
  IRQ7 LPT1
  ...
The problem is the machine has a SoundBlaster, a bus mouse, and I want to
connect a parallel printer (LPT1).  The I/O card manual says that LPT1 can
be IRQ7 or IRQ5, but I can't seem to find out how to change the IRQ of the
bus mouse even though when I type  MOUSE /?  it says its on IRQ5.  So right
now I have the SoundBlaster on IRQ7 but cannot use the parallel port 'cause
it'll lock up.  I could solve this if I could change the IRQ of the bus mouse
to, say, IRQ10 but cannot find out how to do this.  Any ideas?  The video
card does not have any jumpers on it so it is probably software changeable
(if at all).  Another solution might be to change COM1 to IRQ10 but would
this be advisable?

Any info would be greatly appreciated.

Thanks,
  Norm.

P.S.  What the heck is [Cascade]?  Can I still use IRQ2 for something else,
like the SoundBlaster (which again would solve this whole mess).
