2.3 Installing a CPU
The 478-pin Zero Insertion Force (ZIF) socket on the NR-LSR motherboard
supports an Intel Pentium 4 processor. This section tells you how to install a
CPU. Refer to the motherboard user guide for more information.
CPU Socket Location
Locate the 478-pin CPU socket and
note the Pin 1 location.
CPU Orientation
A CPU has a mark (usually a notch
or a gold mark) on one corner to help
you identify the correct orientation
when inserting it to the socket.
Match the marked corner of the CPU
to Pin 1 on the socket.
Incorrect installation of the CPU into the socket may bend the pins
and severely damage the CPU!
