2.5 Clear CMOS (JP3)
This jumper is used to erase CMOS data and reset system BIOS informa-
tion.
The procedure for clearing CMOS is:
1. Turn off the system.
2. Push JP3
3. Turn on the system. The BIOS is now reset to its default setting
2.6 Installing DIMMs
The procedure for installing DIMMs is described below. Please follow
these steps carefully. The number of pins are different on either side of
the breaks, so the module can only fit in one way. DIMM modules have
different pin contacts on each side, and therefore have a higher pin den-
sity.
1. Make sure that the two handles of the DIMM socket are in the
“open” position. i.e. The handles remain leaning outward.
2. Slowly slide the DIMM module along the plastic guides on both
ends of the socket.
3. Press the DIMM module right down into the socket, until you hear
a click. This is when the two handles have automatically locked the
memory module into the correct position of the socket.
To remove the memory module, just push both handles outward, and the
module will be ejected from the socket.
Warning! To avoid damaging the computer, always turn off
the power supply before setting “Clear CMOS.”
Before turning on the power supply, set the
jumper back to “3.0 V Battery On.”
