AMI BIOS
1-1 Introduction
This chapter describes the AMIBIOS for the Intel 440FX 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 Architecture) must have a place to store system information when the
computer is turned off. The original IBM AT had 64 bytes of nonvolatile 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.

BIOS User's Manual
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 Appendix B in
this manual for a list of the various hard disk drive types. Select
User in the Type field if the drive parameters on your MFM drive do
not match any of the drive type in Appendix B.
Entering Drive Parameters
You can also enter the hard disk drive parameters. The drive parameters are:
Parameter Description
Type The number for a drive with certain identification parameters.
Cylinders The number of cylinders in the disk drive.
Heads The number of heads.
Write The size of a sector gets progressively smaller as the track
Precompensation diameter diminishes. Yet each sector must still hold 512 bytes.
Write precompensation circuitry on the hard disk compensates for
the physical difference in sector size by boosting the write
current for sectors on inner tracks. This parameter is the track
number where write precompensation begins.
Landing Zone This number is the cylinder location where the heads will normally
Sectors The number of sectors per track. MFM drives have 17 sectors
Capacity The formatted capacity of the drive is (Number of heads) x

per track. RLL drives have 26 sectors per track. ESDI drives
have 34 sectors per track. SCSI and IDE drive may have even
more sectors per track.

2-1-2 Advanced Setup
Quick Boot
Set this option to Enabled to permit AMIBIOS to boot within 5 seconds. The settings are Disabled or Enabled. The Optimal default
setting is Enabled. The Fail-Safe default setting is Disabled.
1st Boot Device
2nd Boot Device
3rd Boot Device
The options for 1st Boot Device are Disabled, IDE-1, IDE-2, IDE-3,
Floppy, Floptical, SCSI, or Network. The options for 2nd Boot De-
vice are Disabled, IDE-0, or Floptical. The options for 3rd Boot
Device are Disabled, Floptical, or CDROM.
The Disabled option means that setup will not be considered during the boot process. Floppy can be selected only as 1st boot
device. SCSI can be selected only as 1st boot device. CDROM can
be selected only as 3rd boot device. The same device cannot be
chosen more than once. For example, if Floptical is chosen as 2nd
boot device, it cannot be chosen as any other boot device. If IDE-1
2-3
BIOS User's Manual
or IDE-2 or IDE-3 is selected as 1st boot device, IDE-0 cannot be
selected as 2nd boot device. This means that only one IDE device
can be selected as the boot device.
IDE-0, IDE-1, IDE-2, IDE-3 are the four hard disks than can be installed by the BIOS. IDE-0 is the first hard disk installed by the
BIOS, IDE-1 is the second hard disk, and so on. For example, if the
system has a hard disk connected to Primary Slave and another
hard disk to Secondary Master, then IDE-0 will be referred to as the
hard disk connected to Primary Slave and IDE-1 will be referred to
as the hard disk connected to the Secondary Master. IDE-2 and
IDE-3 are not present. Note that the order of the initialization of the
devices connected to the primary and secondary channels are Primary Master first, Primary Slave second, Secondary Master third,
and Secondary Slave fourth.
The BIOS will attempt to read the boot record from 1st, 2nd, and 3rd
boot device in the selected order until it is successful in reading the
booting record. The BIOS will not attempt to boot from any device
which is not selected as the boot device.
Try Other Boot Device
This option controls the action of the BIOS if all the selected boot
devices failed to boot. The settings for this option are Yes or No. If
Yes is selected and all the selected boot devices failed to boot, the
BIOS will try to boot from the other boot devices (in a predefined
sequence) which are present but not selected as boot devices in
the setup (and hence not yet been tried for booting). If selected as
No and all selected boot devices failed to boot, the BIOS will try not
to boot from the other boot devices which may be present but not
selected as boot devices in setup. The Optimal and Fail-Safe default settings are Yes.
Initial Display Mode
2-4
Chapter 2: Running Setup
This option determines the display screen with which the POST is
going to start the display. If selected as BIOS, the POST will start
with the normal sign-on message screen. If Silent is selected, the
POST will start with the silent screen. The settings for this option
are BIOS or Silent. The Optimal and Fail-Safe default settings are
BIOS.
Display Mode at Add-on ROM Init
This option determines the display mode during add-on ROM (except Video add-on ROM) initialization. The settings for this option
are Force BIOS or Keep Current. If selected as Force BIOS, the
POST will force the display to be changed to BIOS mode before
giving control to any add-on ROM. If no add-on ROM is found, then
the current display mode will remain unchanged even if this setup
question is selected as Force BIOS. If selected as Keep Current,
then the current display mode will remain unchanged. The Optimal
and Fail-Safe default settings are Force BIOS.
Floppy Access Control
The settings for this option are Read-Write or Read-Only. The Optimal and Fail-Safe default settings are Read-Write.
Hard Disk Access Control
The settings for this option are Read-Write or Read-Only. The Optimal and Fail-Safe default settings are Read-Write.
