4-1 Introduction
This chapter describes the AMIBIOS for the S2DL3/370DL6/370DL3/370DLE.
The AMI ROM BIOS is stored in a Flash EEPROM and can be easily upgraded
using a floppy disk-based program.
Configuration Data
The original IBM AT had 64 kbytes of non-volatile memory storage in CMOS
RAM. All AT-compatible systems have at least 64 kbytes of CMOS RAM,
which is usually part of the Real Time Clock. Many systems have 128
kbytes 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 on the next page.
A BIOS identification string is displayed at the left bottom corner of the
screen below the copyright message.
