Normally this is set in your system bios. When you boot the machine you
should see a message that says something like:
"Press ??? to enter setup"
Just do that and follow your nose to where you can enable/disable the ps/2
mouse.
That said, there is a good chance that you can go ahead and just use IRQ 12
without making any changes since there is nothing actually connected, it
shouldn't really interfere with another device using that IRQ.

Whoever you bought the computer should be able to supply one but in
practice you'll probably end up buying one for a different motherboard and
hoping that it works. Personally I don't think it's worth the trouble
but...
