four jumpers if you have this CPU on board and it will be auto detected by motherboard. Please
check with the CPU manufacturer or vendor for the CPU Ratio information.
2.1.6 CPU FSB Frequency Setting (Red Jumper Caps)
The JFSB jumper provides three FSB frequency settings for the CPU. Auto Detect , 66MHz or
100MHz FSB frequency can be selected with this jumper. The 100MHz FSB frequency setting is over
specification operation for 66MHz FSB CPU . The over specification operation is not recommended.
2.2 Installation of CPU

2.2.1 For Celeron, Pentium II & III CPU
The motherboard provides a Single Edge Contact(SEC)slot for processor packaged in an SEC
cartridge. Follow these steps to install CPU:
Mount the Universal Retention Mechanism (URM) & Insert the CPU: ( The illustration is just for
reference )
This URM was designed to accommodate 3 types of CPU Form Factor. ( SECC, SECCII & SEPP ). For
Example : Pentium II & Celeron family.
Note : Please put a soft pad under M/B before the installation of URM.
Installation for SECC CPU :
1. Leave space below each mounting hole for the fastener to protrude through the hole.
2. Position URM on the M/B next to the slot1 connector.
3. Push down retainer pin into respective fastener to secure URM onto the M/B.
4. Push CPU into URM to contact with slot1.
5. Make sure latching portion of CPU engaged with windows ledge of URM.
Installation for SECC II or SEPP CPU :
1. Same as step (1) of SECC.
2. Same as step (2) of SECC.
3. Same as step (3) of SECC.
4. Same as step (4) of SECC.
5. Snap in 2 clips into side windows of URM to secure SEPP CPU.
If there is a fan on the CPU, Please plug in the fan cable to the three pin fan connector on the
motherboard (PFAN1).
2.2.2 For Socket 370 CPU
Before installing CPU, make sure the power is off. Locate the level bar on the PGA370 ZIF socket.
Push level bar away from the socket and pull upward 90 degrees. Insert the CPU into the socket.
Make sure the notch of the CPU corresponds with the white dot on the ZIF socket (the corner
without pin socket). Do not push in the CPU. Make sure all pins are aligned with the CPU socket. ON
the level bar.
2.3 Installation of Memory
P2/370A motherboard has 3x168-pin 64-bit Dual Inline Memory Module (DIMM) sockets divided into
3 banks ( P2/370A-Z has 2x168-pin DIMM socket only ). You can install 3.3V Extended Data Output
(EDO)or Unbuffered Synchronous DRAM (SDRAM)memory. This will increase the system reliability.
2.3.1 Installation of 168-pin DIMM (Dual Inline Memory Module)

1. Before inserting the DIMM, make sure the pin1 of the DIMM matches with the pin1 on the DIMM socket.
2. Insert DIMM into the DIMM sockets at a 90-degree angle and press down.
2.3.2 Removal of 168-pin DIMM
1. Press the holding clips on both sides of the socket outward to release the DIMM.
2. Gently pull the DIMM out of the socket.
3.
2.3.3 Memory Configuration
There is no jumper setting required for the memory size or type. It is automatically detected by the
system BIOS, and the total memory size is to add them together.
