2.5 Installing Hardware
※ DO NOT scratch the motherboard when installing hardware. An accidentally
scratch of a tiny surface-mount component may seriously damage the
motherboard.
2.5.1 CPU Socket 478 (Core Duo)
※ Be cautious when installing CPU into this socket. Prevent the contact pins of the
socket and the CPU from breaking or bending.
1. Use a flat-head screwdriver to turn the
screw bolt counter clockwise to unlock
position.
2. Carefully hold the CPU by both of its
edges above the CPU socket. Align the
gold-triangle mark with the Pin-1 of CPU
socket. Place the CPU vertically and
easily down into the socket.
Do not force the CPU in; it only fits in
one orientation.
3. Use a flat-head screw driver to turn the
screw bolt clockwise from its unlock
position to the lock position.
