2.2 INSTALLING THE CPU
The AR-B1665 Embedded Board supports a Socket 370 processor socket for Intel Pentium III (FC-PGA/FC-PGA2)
and Celeron processors. The Board uses a CPU socket called Socket 370 for easy CPU installation. The CPU
should always have a Heat Sink and a cooling fan attached to prevent overheating.
CPU Installation Procedures :
1. Pull the lever sideways away form the socket. Then, raise the lever up to a 90-degree angle.
2. Look for the gold arrow. The gold arrow should point towards the end of lever. The CPU will only fit
in the correct orientation.
3. Hold the CPU down firmly, and then close the lever to complete the installation.
NOTE: Ensure that the CPU heat sink and the CPU top surface are in total contact to avoid CPU overheating
problem that would cause your system to hang or be unstable.
