abit sm5 User Manual

The SM5/SM5-A 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. 

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 SM5/SM5-A series 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. 

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 
SM5/SM5-A’s unique CPU operating frequency and voltage setup feature in order 
to meet modern computing demands.
