4. CMOS RAM Clear: JP17 (Yellow color selector)
WARNING: Make sure your computer is POWER OFF when you 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).

2-7 Central Processing Unit (CPU)

2-7-1 The mainboard provides a Slot-1 for Pentium II/III processor. The CPU on board must have
a fan or heat sink attached to prevent overheating.
WARNING: Without a fan or heat sink, the CPU will overheat 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 Slot- 1 and place
RETENTION MODULE as following:
IMPORTANT: You must set jumper JP14,JP15 for "Bus Frequency Selection" on
the CPU that you install.
1. Attach heat sink to the CPU.
2. Place Part A on slot-1 and gently screw four corners on top of the mother- board.
