AMI BIOS

1-1 Introduction

This chapter describes the AMIBIOS for the Intel 440FX/440LX

chipset which is designed for Intel Pentium® Pro 150/166/180/200

MHz and Pentium II 233/266/300 MHz processors. The AMI ROM

BIOS is stored in the Flash EEPROM and is easily upgraded

using a floppy disk-based program.

System BIOS

The BIOS is the basic input output system used in all IBM®PC,

XT™, AT®, and PS/2®compatible computers. The WinBIOS is a

high-quality example of a system BIOS.

Configuration Data

AT-compatible systems, also called ISA (Industry Standard Archi-

tecture) must have a place to store system information when the

computer is turned off. The original IBM AT had 64 bytes of non-

volatile memory storage in CMOS RAM. All AT-compatible sys-

tems have at least 64 bytes of CMOS RAM, which is usually part

of the Real Time Clock. Many systems have 128 bytes of CMOS

RAM.

How Data Is Configured

AMIBIOS provides a Setup utility in ROM that is accessed by

pressing <Del> at the appropriate time during system boot. Setup

configures data in CMOS RAM.

POST Memory Test

Normally, the only visible POST routine is the memory test. The

screen that appears when the system is powered on is shown on

the next page.

An AMIBIOS Identification string is displayed at the left bottom

corner of the screen, below the copyright message.

1-2 BIOS Features

•supports Plug and Play V1.0A and DMI 2.0

•supports Intel PCI 2.1 (Peripheral Component Interconnect)

local bus specification

•supports EDO (Extended Data Out), ECC and FPM DRAM

•supports ECC (Error Checking and Correction)

•supports Flash ROM

AMIBIOS supports the LS120 drive made by Matsushita-Kotobuki

Electronics Industries Ltd. The LS120:

•can be used as a boot device

•is accessible as the next available floppy drive

AMIBIOS supports the National Semiconductor LM75 and LM78

data acquisition chips. When a failure occurs in a monitored

activity, AMIBIOS can sound an alarm and display a message.

The LM75 and LM78 chips monitor:

•CPU temperature

•additional temperature sensors

•chassis intrusion detector input

•watchdog comparison of all monitored values

•POST code storage RAM

•ISA and I2C serial bus interfaces

•up to five positive voltage inputs

•up to two negative voltage inputs

•up to three fan speed monitoring inputs

BIOS Configuration Summary Screen

AMIBIOS displays a screen that looks similar to the following

when the POST routines complete successfully.

Processor Clock : 200MHz Power Management : APM, SMI

AMIBIOS Setup

See the following page for examples of the AMIBIOS Setup

screen, featuring options and settings. Figure 1-1 shows the

Standard option highlighted. To highlight other options, use the

arrow keys, or use the tab key to move to other option boxes.

Figure 1-2 shows the settings for the Standard setup. Settings

can be viewed by highlighting a desired option and pressing

<Enter>. Use the arrow keys to choose a setting. Note: Optimal

settings for all options can be set automatically. Go to the

Optimal icon in the default box and press <Enter>. Use the

arrow keys to highlight yes, then press <Enter>.

*Optimal and Fail-Safe default settings are bolded in text unless

otherwise noted.

The WinBIOS Setup options described in this section are selected

by choosing the appropriate high-level icon from the Standard Setup

screen. All displayed icons are described in this section, although

the screen display is often all you need to understand how to set

the option.

Choose these icons to configure the hard disk drive. When you

click on an icon, the following parameters are listed: Type, LBA/

Large Mode, Block Mode, 32Bit Mode, and PIO Mode. All param-

eters relate to IDE drives except Type.

If the hard disk drive to be configured is an IDE drive, select the

appropriate drive icon, choose the Type parameter and select

Auto. The BIOS will automatically detect the IDE drive parameters

and display them. Click on the OK button to accept these param-

eters.

Click on LBA/Large Mode and choose On to enable support for

IDE drives with capacities greater than 528MB. Click on Block

Mode and choose On to support IDE drives that use Block Mode.

Click on 32Bit Mode and click on On to support IDE drives that

permit 32-bit accesses.

To configure an old MFM hard disk drive, you must know the drive

parameters (number of heads, number of cylinders, number of

sectors, the starting write precompensation cylinder, and drive

capacity). Select the hard disk drive type (1-46). Refer to table

below.
