Jumpers and Connectors reference
================================
Before installing the mother board,make sure the jumpers setting are set
for your configurationt. The Function of each jumpers are as follows:
Cache Option ........................... JP1,JP2,JP15,JP9,JP10,JP11,JP12
Clock Generator Frequency Selector...... JP17,JP18,JP19
Charge / Discharge CMOS ................ JP13
Speaker Connector ...................... J13
Keylock & Power LED .................... J14
Reset Connector ........................ J15
External Battery Connector ............. J2
Power Supply Connector ................. P1,P2
Keyboard Connector ..................... J1
Micellaneous Jumpers ................... JP34,JP35,JP36,JP39
JUMPER SWITCHES
===============
These switches consist of two or three pins set in a plastic base. Two of
the pins are covered by a cap which connect or short each other. It is
possible to change the switch setting by moving the cap between the first or
last two pins.
JUMPERS OPEN & SHORT
====================
If you wish to change any of the jumper setting, make sure the board is
disconnected from the power source. This is to protect the mother board from
getting damage.
JP13 Charge/Discharge CMOS
==========================
CMOS Charge/Discharge CMOS is used to Charge and Discharge CMOS.
If you discharge the CMOS all datas in the CMOS will be erase. To
discharge CMOS, place a jumper cap in pin 1 & 2 then turn on the Power
supply for 1 to 2 seconds then turn off the power supply. In this procedure
the CMOS is discharge, all the datas in the CMOS is erase. Place the
jumper cap in pin 2 & 3 for CMOS charge,then run setup.
JP13 1-2 Discharge CMOS
JP13 2-3 Charge CMOS
