Power On Self Test (POST)
After the power has been turned on, the system performs a power on self-test to check that all parts are working
properly.
If the test does not find any faults, you will hear one long beep. When the display unit has warmed up, you will
see a message like this:
ROM BIOS #40 Version x.xx
Copyright (c) International Computers Limited 1993
640 kB Base memory
3072 kB Extended memory
The message indicates the BIOS version (here represented by the x letters), and the total amount of memory
installed on the system board (divided into base memory and extended memory).
If the self-test finds any faults it will indicate them in one of the following three ways:
- You will hear two long beeps and see a message on the display unit screen.
- You will hear a sequence of four or eight beeps immediately after you have started the system.
- If you hear five beeps, the BIOS load has been initiated either through SETUP, or by the check done at
hard reset.
The following pages describe the steps that you should take if either fault situation should occur.
Two long beeps and a message
The format these messages take is:
BIOS(code): short description
If you see a message that does not have this format, it probably comes from an additional board installed in the
system unit. For further information, refer to the documentation of the board .
If the keyboard is concerned, the start-up procedure will continue after a while. Otherwise, you will see this
message:
Press <F1> to continue, <INS> for SETUP.
Pressing
F1
allows you to bypass the fault without correcting it. Enter SETUP by pressing the number zero (0) ,
as the message instructs, and check that the configuration parameters are correct (mainly those on the User-
Config screen). Should the message persist, check the following list, and contact service as instructed below.
Error messages 1 to 8 are a summary of what might go wrong during the start-up sequence. They are normally
preceded by one or more of the other error messages. Unlike the rest of the error messages, they are not
intended to indicate a precise error location.
List of messages :
BIOS (1): Keyboard failed
BIOS (2): CMOS failed
BIOS (3): Floppy failed
BIOS (4): Hard disk failed
BIOS (5): Real-time clock test failed
BIOS (6): Memory test failed
BIOS (7): Option PROM failed
The initialisation routine of an option PROM has returned an error indication.
BIOS (8): General self-test error
The system has detected an error during start-up. Possible causes include an incorrect serial
or parallel port set-up, or cache problem.
BIOS(15): Memory cache failure
