Chapter 2 Installing the Mainboard

This AR5 mainboard 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, Cyrix
6x86,  6x86L  and  AMD-K5  processors  now  on  the  market.    (For  details,  see
specifications  in  Chapter  1.)    However,  we  cannot  guarantee  that  the
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
Cyrix

’

s next generation CPUs is unknown at the present time. 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:

Œ

Standard external connectors

•

Jumpers and switches

Ž

Presentation and Installing of the CPU.

•

Installing cache memory--If you don

’

t want to upgrade the cache

memory you can skip this chapter.

•

Installing the system memory.

NNNN

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.
