Chapter 2
This mainboard series not only provides all standard equipment for classic
personal computers, but also provides great flexibility for meeting future upgrade
demands. This chapter will introduce step by step all the standard equipment
and will also present, as completely as possible future upgrade capabilities.
This mainboard is able to support all Intel Pentium including P55C with MMX,

description given in this manual on the circuitry of your mainboard will work for
processors not listed in Chapter 1. For example, the operating voltage of
