Intel Pentium 4 CPU:
• Follow the steps described in this section to install the 478-pin Pentium 4
CPU into the on board Socket 478.
• After installation of Pentium 4 CPU, you must also install the specific
Pentium 4 CPU fan designed in tandem with this CPU. This CPU Fan
installation is described in next section.
1. First pull sideways the lever of
Socket 478, and then turn it up
90 0 so as to raise the upper layer
of the socket from the lower

Adjust the position of CPU until
you can feel all CPU pins get
