WARNING
For the system to operate normally, please make sure J6 of the mainboard is set as below. Refer
to Fig. 2 in this manual for the location J6.
If J6 is shorted to 2-3, no CMOS data can be retained.
CAUTION
The motherboard is an electrostatic sensitive device. Don’t open or handle except at a static-
free workstation.
POWER OFF
It needs to hold the power switch 4 seconds to turn off the power.

CHAPTER 2 JUMPER SETTINGS
2.1 JUMPERS PRESENTATION
Pins 1 and 2 are shorted with a jumper cap.
1 2 3
Pins 2 and 3 are shorted with a jumper cap.
1 2 3
The jumper is shorted when the jumper cap is placed
over the two pins of the jumper.
The jumper is open when the jumper cap is removed
from jumper.
Jumpers Convention
Different color of jumper caps (mini-jumpers) are used on the board to represent
different usage of the jumpers:
Red: CPU Clock setting
Black: Other

2.6 MEMORY CONFIGUARTION
The mainboard lets user upgrade system memory via DIMM sockets on the
mainboard. On board memory is located in eight banks: Bank 0 - 7. Four DIMM
sockets are provided for EDO DRAM or Synchronous DRAM. Table 4 provide the
typical memory configurations supported by the mainboard.
