abit it5 User Manual

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.
