If you hear no beep at all during POST, refer to “Troubleshooting Charts” on
page 86. You might need to have your computer serviced.
Error Messages
Error messages that appear on the screen might be text, numeric, or both. There are
several types of error messages:
POST error messages
Messages that appear when POST finds problems with the hardware during
startup or when a change in the hardware configuration is found. POST error
messages are 3-, 4-, 5-, 8-, or 12-character alphanumeric messages and include
brief explanations (except I999XXXX errors).
For more information about what caused an error message to appear and what
action to take, refer to “Solving POST Error Message Problems” on page 64 and
“POST Message Charts” on page 67.
SCSI error messages
Messages that appear if a problem or conflict is detected by the SCSI host
adapter which is preinstalled in some PC models. If your PC has a preinstalled
SCSI adapter, refer to the SCSI documentation that comes with your computer
for information about these messages.
Software-generated error messages
Messages that appear if a problem or conflict is detected by the application
program, the operating system, or both. Error messages for operating-system
and other software problems are generally text messages, but they also can be
numeric messages. For information about these software error messages, refer
to the information that comes with the operating system or application program,
or both.
Diagnostic error messages
Messages that appear if a hardware problem is detected by a diagnostic test
program. The messages present text information that can be used to identify a
failing part.
