PCI5433
The World’s First
Pipeline Burst Synchronous Cache
PCMSA 5×86/486 System Board
User′s Manual

Introduction

ALD Technology is leading the world in applying the latest Pentium class technology -Pipeline Burst Synchronous SRAM Cache in PCI 5×86/486 system board. This latest caching technology offers significantly higher level 2 cache efficiency over the previous generation of Asynchronous caching. Adding to that, the support of whopping 256 MB on-board DRAM, 4 Mode 4 IDE devices, Plug and Play Flash BIOS ( optional ) and PCI 2.1 compliance enable PCI5433 to perform like Pentium system boards, yet at a much more affordable price.

Features

• AMD/Intel/Cyrix/IBM/ST/T 5×86, 486DX4, DX2 CPU running up to 133 MHz
• 128 KB – 512 KB Pipeline Burst Synchronous Cache
• PCI 2.1 compliant ( 5 V )
• supports 4 ATA PIO Mode 4 Enhanced IDE devices
• 4 to 256 MB Fast Page or EDO DRAM ( auto detection of DRAM type and size )
• 2 16550 compatible Fast UARTs and ECP/EPP parallel port
• 3 PCI ( 2 Master/I Slave ) + 3 ISA 16-bit expansion slots
• floppy interface for 2 360/720/1.44/2.88 drives
• Energy Star Green features
• optional Plug & Play Flash BIOS from AMI or Award
• lithium battery backup for CMOS set-up ALD93C488 single chip core logic

SIMM Installation
All 4 SIMM sockets ( Ml-M4 ) can accept either Single Bank or Double Bank memory modules of Fast Page, EDO or a mixed type of DRAM from 4 MB to a maximum of 256 MB. A maximum of 4 Single Bank SIMM(S) or 2 Double Bank SIMM (D) can be supported :
The minimum memory to start with is a 4 MB Single Bank SIMM, which can be located in any one of the 4 SIMM sockets.
Lithium Battery

• industry standard coin type CR2032
• remove the battery insulator card before power up
• the on-board lithium battery is for the backup of the CMOS holding the Setup information when the system board power is turned off
• depending on the usage pattern, the battery can last for about a year. It should be replaced with a new battery when error message such as CMOS Options not set, Battery is dead, Battery status low appears
• how to replace the battery: turn off the system power, remove the original battery and replace it with a new CR2032 battery

BIOS Setup
Your system board uses either the AMI WinBIOS or Award BIOS ( Basic Input/Output System ). For optimization purpose, most of the BIOS parameters have been pre-determined by the manufacturer. The following steps to do the BIOS setup are the minimum that is required to get started_ Advanced users might want to manipulate the various options to fine tune their hardware to make the most out of their systems. In case there is problem as a result of modifying the BIOS, it is always possible to return to the safe options ( Fail-Safe in AMI BIOS & BIOS Default in Award BIOS ) to start all over again.
AMI BIOS Setup

1. Enter BIOS Setup when prompted during System Boot-up ( press Del during RAM sizing )

2. Choose Standard Setup in the main setup window
   2.1. Set the Date/Time,
   2.2. Set the Floppy A and Floppy B (if any),
   2.3. Set the Master Disk and Slave Dick drive for Primary IDE drives only when the Detect Master and Detect Slave utility fails (see 3 below)
   2.4, Setup the Game Port and the IDE parameters under Peripheral (make sure None is chosen when there is no Secondary IDE drive attached to CN7; Secondary IDE drives can only be set by the BIOS automatically)

3. Auto-detect the Master disk and the Slave disk for the disk drives attached to the Primary IDE Connector (CN8 ) (the Primary IDE drives can be set by either the auto-detect utility under Utility or manually under the Master Disk and Slave Disk in the Standard setup whilst the Secondary IDE drives can only be set by the BIOS automatically.

Award BIOS Setup

1. Enter CMOS Setup Utility page when prompted during System Boot-up ( press Del during RAM sizing )

2. Choose Standard Setup
   2.1. Set the Date/Time,
   2.2. Set the Floppy A and Floppy B (if any )
   2.3. Set the Master Disk and Slave Disk drive for Primary IDE drives only when the Detect Master and Detect Slave utility fails (see 3 below )

3. Choose IDE HDD Auto Detection to detect the Primary Master, Primary Slave, Secondary Master and Secondary Slave accordingly

• You can always enter setup during Vann Boot (pressing Chi, Alt and Del together) by hitting Del when prompted.

  If you forget the Password as set in the Security window, reset the CMOS by

  momentarily touching CNI2 with a metal object (the settings have to be entered again )
