Jumpers are used on this mainboard to
select various settings and features. A 2-pin
jumper has two settings: Open and Short (or
Closed). The jumper is closed by placing the
Jumper Cap across the two pins, thereby
connecting them. 3-pin jumpers can be set
to pins 1-2 or 2-3 connected. Pin-1 is
labeled on the circuit board for jumpers as shown:
JX1: PS/2 Mouse on IRQ12
- JX1 Enables or Disables the on-board PS/2 mouse lead
connector. When pins [2,3] are closed, the port becomes active and IRQ12 is used by the
PS/2 mouse. To disable the PS/2 mouse port, short pins [1,2].
JP5: Clear CMOS RAM
- When closed, the CMOS information is reset to default. All
user-entered information is cleared. To clear the CMOS, first turn the computer off, then
connect a jumper cap over the two pins for a moment. Remove the jumper and power the
system on.
