I personally don't like sharing interrupts unles absolutely necessary.
Can you tell me why you need to do this? I would recommend
disabling any devices you aren't using in the BIOS,
to free up interrupts. (IE 2nd serial port, USB, 1st serial if you
only use PS/2 mouse)
If you don't use the floppy you might be able to disable it in BIOS.
I have one board that will use irq 6 for something more useful in this
case.
Also, changing PCI slot assignment of some cards (if you have spare
slots) can prevent sharing as well.
The BIOS on many boards will show PCI interrupt assignment
on the bootup screen. Otherwise check in windows
device manager - double click on Computer node.
according to the above usage, you could use 4 (com1) (if not mouse or modem)
3 com2
5 unused
9,10,11
for devices.
Good luck!
