*******************************************************************************
- FATAL SYSTEM BOARD BEEP CODES
The table below describes the beep codes and error codes that are
written to Port 80h for fatal system board errors. These errors
will cause the system to halt.
Note: No beep code is sounded if a test is aborted while in progress.
The contents of port 80h can be read to identify the area of failure.

available--strike F1 the hard disk, or the doesn't work, replace
to retry boot diskette itself is the floppy diskette or
defective the hard disk

No boot sector on hard The C:drive is not Format the C: drive
disk--strike F1 to formatted

stopped chip has failed

Timer chip counter 2 Check the timer chip
failed system board

Timer or interrupt Either the timer chip or Check the timer chip
controller bad the Interrupt Controller is of the Interrupt
defective controller on the
system board

Unexpected interrupt in The non-maskable interrupt Check the system
protected mode (NMI) port can't be board, particularly
disabled the logic associated
with the non-maskable
interrupt

*******************************************************************************
- POST INFORMATIONAL MESSAGES
The table below lists the POST information messages and their meanings.
*******************************************************************************
____________________________________________________
INFORMATIONAL MESSAGE MEANING
====================================================
Hex-value Base Memory, Indicates the amount of
hex-value Expansion memory that has tested
successfully

Decreasing available Immediately follows any
memory memory error message, and
informs you that the memory
chips are failing

Memory test terminated Indicates that you have
by keystroke pressed the Spacebar while
the memory tests were
running. This stops the
memory tests.

- RUN-TIME ERROR MESSAGES
Run-time messages are displayed if an error occurs after the
boot procedure is complete. The table below gives possible
causes and solutions for the run-time messages.
