POST Error Messages List
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".
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.

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.
The system may run specific disk diagnostic Routines. This message appears if one or more
hard disks return an error when the diagnostics run.
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.
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.
This message displays during a full memory test, counting down the memory areas being
tested.
If POST detects an error during memory testing, additional information appears giving
specifics about the type and location of the memory error.
