Chapter 1 Introduction of AR5
Features
The AR5 have been especially designed for File server, Workstation and Professional users. It can support a wide range of processors, including all Intel CPUs (P54C) and Intel CPUs with MMX (P55C), as well as all
The AR5 uses SOFT MENU™ technology, which means that all the parameters can be configured without using DIP switches or jumpers. The configuration is entirely achieved through a “Soft Switch” that allows the user to set CPU speed and operating voltage with ease.
The AR5 uses Intel 430VX series chipsets, and has 256K or 512K
Two
The AR5 also provides two Universal Serial Bus (USB) ports and meets the Concurrent PCI Rev. 2.1 standard. It also supports IDE interface for Fast HDD (Mode 0~4), as well as IDE Bus Master. These features also meet present and future interface standards and needs.
System BIOS features include

Installing the Mainboard |
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
This chapter is organized according the following features: Œ Standard external connectors
• Jumpers and switches
Ž Presentation and Installing of the CPU.
•Installing cache
•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.
