Gateway 920 User Manual page 93

Several POST routines issue a POST terminal error and shut down the system
when they fail. Before shutting down the system, the terminal error handler
sounds a beep code (one long tone and a series of short tones) that identifies
the test point error. If POST completes normally, the BIOS issues one short beep
before passing control to the operating system.
Beeps Description
1 Refresh failure. The memory
refresh circuitry on the system
board is faulty.
2 Parity error. Parity error in the first
64 KB of memory.
3 Base 64 KB memory failure.
Memory failure in first 64 KB.
4 Memory failure in first 64 KB of
memory, or Timer 1 on the system
board not functioning.
5 The processor on the system board
generated an error.
6 The keyboard controller (8042) may
be defective. The BIOS cannot
switch to Protected mode.
7 The processor generated an
exception interrupt.
8 The server video adapter is either
missing or its memory is faulty. This
is not a fatal error.
9 The ROM checksum value does not
match the value encoded in the
BIOS.
Troubleshooting steps
Reseat the memory or replace with known
good modules.
Same as for 1 beep.
Same as for 1 beep.
Remove all expansion cards.
If the beep codes occur even when all
■
expansion cards have been removed, the
system board is at fault.
If the beep codes do not occur when the
■
expansion cards have been removed, one
of the cards is causing the problem. Install
the cards one at a time until the problem
happens again. When the beep codes
return, the most recent card you installed
is at fault.
