Introduction of AR5 Features
Chapter 1
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 AMD-K5 and
Cyrix 6x86/6x86L CPUs. It also takes into account, as much as possible, all
future CPUs.
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 Level-2
Pipeline Burst SRAM on board. It also provides an extension slot allowing the
user to upgrade Pipeline Burst SRAM to 512K.
Two 168-pin DIMM slots and four 72-pin SIMM slots meet the
requirements for all memory configurations required by high level computing.
The 168-pin DIMM slots support traditional Fast Page and EDO DRAM as a
memory standard for next generation 64-bit systems. The two 168-pin DIMM
slots have been reserved to meet requirements for both present and future
upgrades.
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 Plug-and-Play (PnP), Advanced Power
Management (APM), the newest Desktop Management Interface (DMI), as well
as AR5's unique CPU operating frequency and voltage setup feature in order to
meet modern computing demands.
