Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
1.6 Central Processing Unit (CPU)
The Intel ® Pentium ® 4 processor has a gold triangular mark on one corner.
This mark indicates the processor Pin 1 that should match a specific corner
of the CPU socket.
Your boxed Intel ® Pentium ® 4 processor package should
come with installation instructions for the CPU, fan and heatsink
assembly. If the instructions in this section do not match the CPU
documentation, follow the latter.
Before installing the CPU, make sure that the socket box is facing
towards you and the load lever is on your left.

the lever sideways, then lift it up
to a 90°-100° angle.

lever is lifted up to 90°-100°
angle, otherwise the CPU does
not fit in completely.
