Chapter 1: BIOS Overview
The Mylex System BIOS was developed to ensure
compatibility for building advanced personal computer
systems or workstations. The 486 System BIOS sup-
ports the highest performance 80486, as well as the
widest range of products on the Extended Industry
Standard Architecture (EISA) bus.
BIOS
The
specification for system boards provides for
Structure
ROM based firmware that is integrated within the
overall system. Mylex has developed this software,
usually referred to as the “BIOS” for use with their
system boards. The system BIOS
contains three functiontional components. They are:
l
System BIOS (Basic
system)
This is a collec-
tion of routines and interrupt handlers that are used
by industry standard software to perform
opera-
tions on commonly used devices.
System POST (Power-on Self Test)
This pro-
gram receives control when power is initially ap-
plied to the system or a system reset operation is
performed.
l
System SETUP
This program is run when the
CMOS database provided on the system board
requires modification.
This manual describes the POST routine, the SETUP
routine, and the operational error messages provided
by the system BIOS from a user’s point of view.
