Appendix A BIOS Messages

BIOS BEEP CODES Errors may occur during the POST (Power-On Self Test) routines which are performed each time the system is powered on.

Non-fatal errors are those which, in most cases, allow the system to continue the bootup process. The error message normally appears on the screen. See BIOS Error Messages later in this appendix for descriptions of these messages.

Fatal errors are those which will not allow the system to continue the bootup procedure.

These fatal errors are usually communicated through a series of audible beeps. Each error message has its own specific beep code, defined by the number of beeps following the error detection. The following table lists the errors which are communicated audibly.

All errors listed, with the exception of #8, are fatal errors.

Description

 

 

 

1

Refresh Failure

The memory refresh circuitry of the processor

 

 

board is faulty.

2

Parity Error

A parity error was detected in the base memory

 

 

(the first block of 64KB) of the system.

3

Base 64KB Memory

A memory failure occurred within the first 64KB

 

Failure

of memory.

4

Timer Not Operational

A memory failure occurred within the first 64KB

 

 

of memory, or Timer #1 on the processor board

 

 

has failed to function properly.

5

Processor Error

The CPU (Central Processing Unit) on the

 

 

processor board has generated an error.

6

8042 - Gate A20 Failure

The keyboard controller (8042) contains the

 

 

Gate A20 switch which allows the processor to

 

 

operate in protected mode. This error message

 

 

means that the BIOS is not able to switch the

 

 

processor into protected mode.

7

Processor Exception

The processor on the SBC has generated an

 

Interrupt Error

exception interrupt.

8

Display Memory

The system video adapter is either missing or

 

Read/Write Error

its memory is faulty.

 

 

NOTE: This is not a fatal error.

9

ROM Checksum Error

The ROM checksum value does not match the

 

 

value encoded in the BIOS.
