If you have a PS/ 2 mouse not a serial mouse, it usually uses IRQ 12 in both
Win95 and Win 98 which may be why you are having an IRQ conflict.  A PS/2
mouse does not share an IRQ.  Enable IRQ steering as Bill Cohane explained
and try reinstalling the card.  If the conflict is caused by the PS/2 mouse
using IRQ 12 that should hopefully fix it.  I have had trouble with Plug and
pray not assigning IRQ's properly and have to assign them in the Bios
myself.
