Chapter 4. BIOS Setup
The ROM chip of your R286A board is configured with a customized Basic
Input/Output System (BIOS) from AMI BIOS. The BIOS is a set of permanently
recorded program routines that give the system its fundamental operational
characteristics. It also tests the computer and determines how the computer reacts
to instructions that are part of programs.
The BIOS is made up of code and programs that provide t he device-level control for
the major I/O devices in the system. It contains a set of routines (called POST, for
Power-On Self Test) that check out the system when you turn it on. The BIOS also
includes BIOS setup program, so no disk-based setup program is required CMOS
RAM stores information for:
Date and time
Memory capacity of the appliance
Type of display adapter installed
Number and type of disk drives
The CMOS memory is maintained by battery installed on the MB-80150 board. By
using the battery, all memory in CMOS can be retained when the system power
switch is turned off. The system BIOS also supports easy reload of the CMOS data
when you replace the battery or battery loses power.
