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

2.5 J2 - VOLTAGE SELECTION FOR SYSTEM ROM
J2 is used to select the operation voltage of the system ROM.
Table 3: Voltage Selection for System ROM
2.6 MEMORY CONFIGUARTION
When 100MHz Front Size Bus Pentium II Processor is used. SDRAM DIMMs with
PC/100 specification and Serial Presence Defect (SPD) data structure are required.
For 66MHz Front Size Bus Pentium II Processor, SDRAM or EDO DIMM may be
used. Don’t use both SDRAM and EDO DIMM at the same time.
To enable the Error Checking and Correction (ECC) feature of the chipset. ECC
DIMM has to be used and the “DRAM Data Integrity Mode” on BIOS Chipset
Features Setup Menu has to be set to “ECC”.
Three DIMM sockets are provided for the 3.3V SDRAM or EDO:
DIMM1 - used memory rows 0 and 1
DIMM2 - used memory rows 2 and 3
DIMM3 - used memory rows 4 and 5
Table 4 provides the typical memory configurations supported by the mainboard.

The maximum memory size is up to 768MB. The size of each DIMM can be 8MB,
16MB, 32MB, 64MB, 128MB or 256MB.
