This chapter describes jumpers, connectors and hardware devices of this motherboard.
Note: El ectrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and
other components. Always observe the following precautions before you install a system component.
1. Do not remove a component from its protective packaging until you are ready to install it.
2. Wear a wrist ground strap and attach it to a metal part of the system unit before handling a
component. If a wrist strap is not available, maintain contact with the system unit t hroughout any
procedure requiring ESD protection.

You can clear CMOS to restore system default setting. To clear the CMOS, follow the procedure below.
1. Turn off the system and unplug the AC power.
2. Remove ATX power cable from connector PWR2.
3. Locate JP14 and short pins 2-3 for a few seconds.
4. Return JP14 to its normal setting by shorting pins 1 & pin2.
5. Connect ATX power cable back to connector PWR2.

This motherboard supports Intel® Pentium III®(Both Coppermine and Tualatin are supported) and Celeron™ Socket 370 series
CPU. Be careful of CPU orientation when you plug it into CPU socket.
1. Pull up the CPU socket level and
up to 90-degree angle.
2. Locate Pin 1 in the socket and look for a black dot or cut edge on t he
CPU upper interface. Match Pin 1 and cut edge, then insert the CPU into
the socket.

DIMM can be single side or double side; it has 64 bit data and 2 or 4 clock signals. We strongly recommend choosing 4-clock
SDRAM for its reliabil ity
Note: Based on VIA Apollo Pro 133T chipset specification, we
recommend you that using double-side SDRAM modules with DIMM
socket 1 & 2. By the way, do not insert the single-side DIMM module
in the DIMM socket 4 when DIMM socket 3 left blank. This will cause
the size report error of DIMM.
