NOTE:
1.
Before installing the CPU, Please check the CPU Frequency and Clock Ratio from your
supplier.
2. For Cyrix/IBM 6X86MX series, please double check the CPU’s Frequency and Clock Ratio.
1. CMOS RAM: JP12 (Yellow color selector)
WARNING: Make sure your computer is POWER OFF when you are CLEAR CMOS.
Connect a jumper Cap over this jumper for a few seconds, will clears information stored in the
CMOS RAM Chip that input by user, such as hard disk information and passwords. After
CLEAR CMOS, you must enter the BIOS setup (by holding down <DEL> during power-up) to
re-enter BIOS information (see BIOS SETUP).

2-4 Central Processing Unit (CPU)
The main board provides a 321-pins ZIF Socket 7. The CPU on mother board must have a fan
attached to prevent overheating.
WARNING: Without a fan, the CPU will be overheated and cause damage to both the CPU and the
motherboard.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket and open
it by first pulling the lever sideways away from the socket then upwards to a 90-degree right angle.
Insert the CPU with the white dot as your guide. The white dot should point towards the end of
the level. The CPU has a corner pin for three of the four corners, the CPU will only fit in the one
orientation as shown as follow. With the added weight of the CPU fan, no force is required to
insert the CPU. Once completely inserted, hold down on the fan and close the socket’s lever.
