RRORS
If an error is encountered during the diagnostic checks performed when the system is powered on, the error
is reported in one of two different ways:
1) If the error occurs before the display device is initialized, a series of beeps is transmitted.
2) If the error occurs after the display device is initialized, the screen displays the error message. In
the case of a non-fatal error, a prompt to press the
<F1>
key may also appear on the screen.
Explanations of the beep codes and BIOS error messages may be found in
Appendix A - BIOS Messages
.
As the POST routines are performed, test codes are presented on Port 80H. These codes may be helpful as a
diagnostic tool and are listed in
Appendix A - BIOS Messages
.
If certain non-fatal error conditions occur, you are requested to run the BIOS Setup Utility. The error
messages are followed by this screen:

Running AMIBIOS Setup
AMIBIOS Setup keeps a record of system parameters, such as date and time, disk drives and other user-
defined parameters. The Setup parameters reside in the Read Only Memory Basic Input/Output System
(ROM BIOS) so that they are available each time the system is turned on. The BIOS Setup Utility stores
the information in the complementary metal oxide semiconductor (CMOS) memory. When the system is
turned off, a backup battery retains system parameters in the CMOS memory.
Each time the system is powered on, it is configured with these values, unless the CMOS has been
corrupted or is faulty. The BIOS Setup Utility is resident in the ROM BIOS so that it is available each time
the computer is turned on. If, for some reason, the CMOS becomes corrupted, the system is configured with
the default values stored in this ROM file.
As soon as the system is turned on, the power-on diagnostic routines check memory, attempt to prepare
peripheral devices for action, and offer you the option of pressing
<Del>
to run the BIOS Setup Utility.
If certain non-fatal errors occur during the Power-On Self Test (POST) routines which are run when the
system is turned on, you may be prompted to run the BIOS Setup Utility by pressing
<F1>
