Introduction
This chapter describes the AMIBIOS for the VIG705P motherboard. The AMI ROM
BIOS is stored in a Flash EEPROM and can be easily upgraded using a floppy disk-
based program.
Note!
Due to periodic changes to BIOS, some settings may have been added or deleted
and might not yet be recorded in this manual. Refer to the Manual Download area of
our web site for any changes to BIOS that are not reflected in this manual.
System BIOS
The BIOS is the Basic Input Output System used in all IBM ® PC, XT™, AT ®, and
PS/2 ® compatible computers. The BIOS ROM stores the system parameters, such
as amount of memory, type of disk drives and video displays, etc. BIOS ROM
requires very little power. When the computer is turned off, a back-up battery
provides power to the BIOS ROM, enabling it to retain the system parameters. Each
time the computer is powered-on, the computer is then configured with the values
stored in the BIOS ROM by the system BIOS, which gains control when the
computer is powered on.
How to Change the Configuration Data
The configuration data that determines the system parameters may be changed by
entering the BIOS Setup utility. This Setup utility can be accessed by pressing <Del>
at the appropriate time during system boot.
Starting the Setup Utility
Normally, the only visible POST (Power On Self Test) routine is the memory test. As
the memory is being tested, press the <Delete> key to enter the main menu of the
BIOS Setup utility. From the main menu, you can access the other setup screens,
such as the Chipset and Power menus.
An AMIBIOS identification string is displayed at the left bottom corner of the screen,
below the copyright message.
