Chapter 4

If you cannot run the diagnostics program tests but did receive a POST error message, use “POST Error 
Messages List” to diagnose system problems. If you did not receive any error message, look for a description 
of your error symptoms in “Error Symptoms List” on page 120

.

NOTE: When you have deemed it necessary to replace an FRU, and have done so, you must run a total 

system check to ensure that no other activity has been affected by the change. This system check can 
be done through the diagnostics program.

NOTE: Check all power supply voltages, switch, and jumper settings before you replace the main board. Also 

check the power supply voltages if you have a “system no-power” condition. 

If you are unable to correct the problem by using the “BIOS Messages List” table and “Error Symptoms List” 
table, go to “Undetermined Problems”.

To diagnose a problem, first find the BIOS error messages in the left column. If directed to a check procedure, 
replace the FRU indicated in the check procedure. If no check procedure is indicated, the first Action/FRU 
listed in right column is the most likely cause.

BIOS ROM checksum error - System halted

The checksum of the BIOS code in the BIOS chip is 
incorrect, indicating the BIOS code may have become 
corrupt. Contact your system dealer to replace the BIOS.

CMOS Battery Failed

The CMOS battery is no longer functional. Contact your 
system dealer for a replacement the BIOS.

CMOS Checksum Error- defaults loaded

Checksum of CMOS is incorrect, so the system loads the 
default equipment configuration. A checksum error may 
indicate that CMOS has become corrupt. A weak battery 
may have caused this error. Check the battery and replace 
if necessary. 

CPU at nnnn

Displays the running speed of CPU.

Display switch is set incorrectly

The display switch on the motherboard can be set to either 
monochrome or color. This message indicates the switch is 
set to a different setting than indicated in Setup. Determine 
which setting is correct, and then either turn off the system 
and change the jumper, or enter Setup and change the 
Video selection. 

Press ESC to skip memory test

The user may press Esc to skip the full memory test.

Floppy disk(s) fail

Cannot find or initialize the floppy drive controller or the 
drive. Make sure the controller is installed correctly, if no 
floppy drives are installed, be sure the Diskette Drive 
selection in Setup is set to NONE or AUTO.

HARD DISK initializing - Please wait a moment

Some hard drives require extra time to initialize.

HARD DISK INSTALL FAILURE

Cannot find or initialize the hard drive controller or the 
drive. Make sure the controller is installed correctly. If no 
hard drives are installed, be sure the Hard Drive Selection 
in Setup is set to NONE.

Hard disk(s) diagnosis fail

The system may run specific disk diagnostic routines. This 
message appears if one or more hard disks return an error 
when the diagnostics run.

Keyboard Error Or No Keyboard Present

Cannot initialize the keyboard. Make sure the keyboard is 
attached correctly and no keys are pressed during POST. 
To purposely configure the system without a keyboard, set 
the error halt condition in Setup to HALT ON ALL, BUT 
KEYBOARD. The BIOS then ignores the missing keyboard 
during POST.

Keyboard is locked out - Unlock the key

This message usually indicates that one or more keys have 
been pressed during the keyboard tests. Be sure no 
objects are resting on the keyboard.
