J38 is a three-pin berg that enables the PS/2 mouse
interrupt (IRQ12). Short Pins 1-2 of J38 to enable
IRQ12 as the PS/2 mouse interrupt. You should
always short Pins 1-2 of J38 to enable the PS/2

have to short Pins 2-3 of J38 is if you wanted an

would then have to set the PS/2 Mouse option in
Advanced Setup to Disabled, and set the IRQ12
option in Advanced Setup to
the PS/2 mouse by setting the
in Advanced Setup in WINBIOS Setup to
or Disabled.
