Chapter 5
AMI BIOS POST
The AMI BIOS resides on the EZ-Flex CPU Card. The
AMI EISA BIOS provides all standard POST (Power-On
Self Test) routines, as well as AMI POST routines. AMI
POST supports CPU internal diagnostics. AMI POST codes
are accessible via the Manufacturing Test Port (I/O Port
80h).

POST Phases

When the system is powered on, the Hi-Flex BIOS executes
POST, which has two phases:
System Test and Initialization (test and initialize Base
Boards for normal operations) and
System Configuration Verification (compare defined
configuration with hardware actually installed).

BIOS Error Reporting

The AMI BIOS reports errors in one of two ways:
If...
the error occurs before the display
device is initialized,
the error occurs after the display
device is initialized,
50
Then...
a series of beeps sound. Beep codes indicate that a fatal
error occurred. The AMI BIOS Beep Codes are described on
the next page.
the error message is displayed. Displayed BIOS error
messages are explained below. A prompt to press <F1> can
also appear. See page 52.
