I have Windows NT server 4.0
PS 2 type mouse on board and I want to install a sound card.
The sound card has an ess es 1886 driver NT 4.0
but once I plug the sound card into the Slot (it is not a pci card) then my
mouse freezes.
I can't instal the sound card because no mouse.
The PS 2 IRQ is 12 (standard) it should not interfere with the sound card.
any suggestions are very welcomed
bets regards
