2-2 Installing a PGA type CPU in a ZIF Socket
The Intel Socket 7, designed for the Pentium processor, has been incorporated as
a standard mainboard specification and is compatible with AMD and Cyrix CPUs. To
insert your CPU into Socket 7 please do the following:
1. Locate a small dot marked on the top surface of the CPU close to one if it's corners.
The same corner will also be cut off, leaving a noticeable notch in the CPU's corner.
These markings indicate Pin 1 of the CPU. See Figure 2-2.
2. Pull up the lever of Socket 7 so that it is perpendicular with the surface of the
mainboard. Gently insert the CPU with Pin 1 at the same corner of Socket 7 that
contains the end of the lever. Allow the the weight of the CPU to push itself into
place. Do not apply extra pressure as doing so may result in damaging your CPU.
Snap the lever back into place. See Figure 2-3.
Installing a heat sink and cooling fan on top of your CPU is necessary for
proper heat dissipation. Failing to install these items may result in overheating
and possible burn-out of your CPU.
