Preparing The Mainboard - ECS P6SEP-Me User Manual

Preparing the Mainboard

Prepare the main board by installing the Celeron Pentium-II processor and then
installing either 1, 2 or 3 memory modules. This board supports the new generation
Celeron processor that is packaged in a Plastic Pin Grid Array (PPGA) designed to fit
the PGA370 ZIF socket on the mainboard. You can use a Celeron that runs at either 300,
333, 366, 400 or 500 MHz. Next, install one or more memory modules. Finally, review
all the important jumper settings to ensure that the board is configured correctly.
Install the Processor
This mainboard is installed with a PGA370 ZIF processor socket. This socket will only
support the PPGA Celeron processor. Do not try to insert a socket-7 processor such as a
Pentium or Pentium-compatible processor. The Celeron processors all run over a 66
MHz system bus and have internal clock speeds ranging from 300 to 433 MHz.
Configuration of the processor is made automatically using the mainboard BIOS (see the
Setup chapter).
Follow the steps below to install the Celeron processor in the PGA370 socket.
1. Locate the zero insertion force (ZIF) PGA370 socket for the processor.

2. On the socket and on the processor, identify the pin 1 corner. You can identify the
pin 1 corner by noting that in the rectangular matrix of holes on the socket, one hole
is absent on two corners. The front corner with the absent hole is the pin-1 corner.
On the processor, the pin-1 corner is beveled (see the illustration below).
3. Push the socket locking lever away from the socket to unhook it. Swing the lever
into the upright position.
4. Insert the processor into the socket taking care that you have matched the pin 1
corners. No force is required, and the processor should seat smoothly into the
socket.
