I checked again and I see that Windows gives the user a bit
more flexibility in controlling resources than PS2.EXE does.
In Windows Settings|Control Panel|System once can set the
IR interface to use IRQ 5 as well as 3 and 4.  The IBM
Technical Reference confirms this.  I don't have a complete
list of irq "compatibility" for all devices handy though.
I have posted the choices available under PS2.EXE on my site
in the "resources" section:
