Installing the Mainboard 2- 1
Chapter 2 Installing the Mainboard
This IT5A mainboard not only can be used with all standard equipment for
traditional 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 chips including
P55C with MMX, Cyrix 6x86MX and AMD-K5/K6/K6-3D processors now on
the market. (For details, see specifications in Chapter 1.) However, we cannot
guarantee the description given in this manual of the circuitry of your mainboard
will work for processors not listed in Chapter 1. For example, the operating
voltage of Cyrix’s next generation CPU is unknown at present. Thus we were not
able to include these specifications in your motherboard. We will supply further
information about CPU support when new CPUs arrive on the market.
This chapter is organized according the following features:
ΠInstalling the Mainboard to the Casing
• Standard external connectors
Ž Jumpers and switches
• Presentation and Installing of the CPU.
º Installing the system memory.

Before proceeding with the installation
Before installing the mainboard please be sure to turn off or disconnect the
power supply unit. Before making any modifications to the hardware
configuration of the mainboard, the power supply to any areas of the mainboard
you plan to modify should be turned off to avoid unnecessary damage to the
hardware.
