Installing a Socket-370 Processor
A processor installs into the ZIF (Zero Insertion Force) Socket-370
on the mainboard.
1. Locate the Socket-370 and CPUFAN1. Pull the locking lever
out slightly from the socket and raise it to the upright position.
2. On the processor, identify the Pin-1 corner by its beveled edge.
3. On the Socket-370, identify the Pin-1 corner. The Pin-1 corner
is at the end of the locking lever when it is locked.
4. Match the Pin-1 corners and insert the processor into the
socket. No force is required and the processor should drop into
place freely.
5. Swing the locking lever down and hook it under the catch on
the side of the socket. This secures the CPU in the socket.
6. All PPGA Celeron and FCPGA Coppermine processors should
be installed with a combination heatsink/cooling fan, connect
the cable from the fan to the CPU fan power connector
CPUFAN1.
Install Memory
The mainboard has two DIMM sockets for system memory
modules. You must install at least one memory module in order to
use the mainboard.
