AMI BIOS
1-1 Introduction
This chapter describes the AMIBIOS for the Intel 430 TX chipset
which is designed for an Intel Pentium®75/90/100/120/133/150/
166/180/200/233 MHz, Cyrix/IBM 5x86, 6x86, AMD-K5, AMD-K6 and
MMXTM processors. The AMI ROM BIOS is stored in the Flash
EEPROM and is easily upgraded using a floppy disk-based pro-
gram.
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 Architec-
ture) 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 systems
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
below.
An AMIBIOS Identification string is displayed at the left bottom
corner of the screen, below the copyright message.

Running Setup
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
parameters 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 parameters.
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.
