2.4.12 PGA370 CPU Socket
The motherboard provides a ZIF Socket 370. The CPU that comes with the
motherboard should have a fan attached to it to prevent overheating. If it is not so,
purchase a fan before you turn on your system.
Notice !!!
Be sure that there is a sufficient air circulation across the processor
’
s heatsink
by regularly checking that your CPU fan is working. Without sufficient circu-
lation, the processor could be overheated and it may damage both the processor
and the motherboard. You may install an auxiliary fan, if necessary.
Installation step:
1. Turn off the power of your system and remove its cover;
2. Locate the ZIF socket and open it by first pulling the lever sideways away
from the socket then upwards to a 90-degree angle;
3. Insert the CPU with correct orientation
(The CPU has a corner pin for two of the four corners, that the CPU only fit in the
orientation.)
4. Once completely inserted, pull down the socket
’
s lever to horizontal and make
sure the CPU is firmly locked in the socket.

as a CD-ROM, MPEG card. The Modem connector allows the onboard audio to
interface with an voice modem card with a similar connector. It also allows the
sharing of mono_in (such as a phone) and mono_out(such as a speaker) between
the onboard audio and the voice modem card.
