Introduction of IT5 Series Features 1-1
Chapter 1 Introduction of IT5
Series Features
The IT5 series has 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.
This series 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 IT5 series uses Intel 430VX and 430HX 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.
This series 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 IT5’s unique CPU operating frequency and voltage setup feature in
order to meet modern computing demands.
