Chapter 4: System BIOS What is the BIOS? The BIOS (Basic Input Output System) is an important piece of software which is stored in a ROM (Read Only Memory) chip inside the computer. It consists of the basic instructions for controlling the disk drives, hard disk, keyboard and serial/parallel ports. The BIOS also keeps a list of the specifications of the computer in battery-backed RAM (also known as the CMOS RAM) and provides a special Setup program to change this information.
Phoenix Award BIOS Introduction The motherboard uses a Phoenix BIOS, which is stored in flash memory and can be upgraded using a disk-based program. In addition to the BIOS, the flash memory contains the Setup program, Power-On Self Test (POST), Advanced Power Management (APM), the PCI auto-configuration utility, and is Windows 95-ready Plug and Play. This motherboard supports system BIOS shadowing, allowing the BIOS to execute from 64-bit onboard write-protected DRAM.
When the BIOS update process is complete, the utility reboots the system. Once the system has been restarted it will hold on the Pre-BIOS screen. At this stage the following need to be completed before starting windows. 1. The system will halt on pre-BIOS, at this point you need to shut the machine down. 2. Reboot the computer. 3. System will holt on the pre-BIOS screen and display an error message (CMOS checksum error – Defaults loaded) 4. Enter the BIOS setup by pressing DEL 5.
Configuring the Motherboard using BIOS Setup Before You Begin CAUTION! Always follow the steps in each procedure in the correct order. Set up a log to record information about your computer, such as model, serial numbers, installed options, and configuration information. Use an anti-static wrist strap and a conductive foam pad when working on the motherboard.
BIOS Setup Program This motherboard supports a programmable firmware hub (FWH) that you can update using the provided utility described in section “2.1 Managing and updating your BIOS.” Use the BIOS Setup program when you are installing a motherboard, reconfiguring your system, or prompted to “Run Setup”. This section explains how to configure your system using this utility. Even if you are not prompted to use the Setup program, you may want to change the configuration of your computer in the future.

Chapter 5: Technical Information NOTE: This chapter is indented for experienced users only, and only to be used as a reference. Changes to or modify any of the components/ connectors listed herein can and will seriously damage your system, including the motherboard, CPU and/or any other hardware. You do not need to read this chapter to configure your motherboard. If you are not sure about the details listed herein, please skip and disregard them.
choice is to utilise Extended CHS mode if the drive topology allows. If neither of the above methods is possible, the Standard CHS mode is used. Different operating systems have different abilities regarding IDE translation mode. UNIX operating systems (as currently implemented) do not support either LBA or ECHS and must utilise the standard CHS method. UNIX can support drives larger than 528MB, but does so in its own way. OS/2 2.1 and OS/2 Warp can support LBA, ECHS or standard CHS methods.
Other Information Reliability The mean time between failures (MTBF) prediction is calculated using component and subassembly random failure rates. The calculation is based on the Bellcore Reliability Prediction Procedure, TR-NWT-000332, Issue 4, September 1991. The MTBF prediction is for: Redesigning the motherboard for alternate components if failure rates exceed reliability expectations. Estimating repair rates and spare parts requirements. MTBF data is calculated from predicted data @ 55 C.
Chapter 6: Glossary BIOS (Basic Input Output System) This is software stored on a chip and consists of the instructions necessary for the computer to function. The System BIOS contains the instructions for the keyboard, disk drives etc., and the VGA BIOS controls the VGA graphics card. CPU Central Processing Unit. This is the main piece of equipment on the motherboard. The CPU processes data, tells memory what to store and the video card what to display.
This causes a slight flicker, so generally non-interlaced mode is better if the monitor supports it. L.E.D. Light Emitting Diode - a light which indicates activity - for example hard disk access. PCI Peripheral Component Interface. It became apparent to manufacturers that the 8MHz AT ISA BUS on the standard PC was just not fast enough for today's applications, and so PCI was invented. It is a high speed data bus that carries information to and from components - known as 'Local Bus'.
