2.4.1 CMOS clear (JP1)
2.4.2 PCI VIO Select (JP3)
It is a PCI I/O voltage selection. It has VCC(+5V), VCC3(+3.3V) and
NULL.
Caution! Always ground yourself to remove any static
charge before touching the PC board. Modern
electronic devices are very sensitive to static
electric charges. Use a grounding wrist strap at
all times. Place all electronic components on a
static-dissipative surface or in a static-shielded
bag when they are not in the chassis.
Warning! To avoid damaging the computer, always turn off
the power supply before setting “Clear CMOS.”
Set the jumper back to “3V Battery On” before
turning on the power supply.
