Pentium CPU Board

The Pentium CPU board contains the Pentium CPU, 512-KB second-level
cache expandable to 1 MB, four 72-pin SIMM sockets, and another socket for
a second Pentium CPU.

A system with a Pentium CPU Board can easily be upgraded to a multiprocessor
system. To upgrade to two Pentium CPUs, simply install the second CPU into
the upgrade socket.

When you upgrade to a higher speed Pentium CPU, you have to change the
oscillator with a higher speed also.

WARNING!

Do not attempt to make any hardware changes in your
system if you are not a qualified technician. Ask your
dealer for assistance.

Figure 4-1 shows the Pentium CPU board layout.
