Installing a Processor
The system board has two sockets for Pentium II Processors. Figure 4-4 illustrates the
location for the optional Pentium processor in your system. When adding a second
processor, use
the same type and speed as the processor shipped with your system.
Contact your sales representative.
Note:
Installing a second processor that is of a different type
than the first processor, will result in system damage. Do not touch
or bend the processor's exposed pins.
Note:
The voltage module for CPU 2 should not be installed in
a mono processor system.
