POST error messages
Error code Error message Corrective action
0251 System CMOS
checksum bad - Default
configuration used
The settings in the Setup Utility have been corrupted or modified
incorrectly, perhaps by an application program that changes
data stored in CMOS.
You can either load the system default values or access Setup and
enter your own custom values. If the error persists, check the
system battery or contact your HP Customer Support provider.
0260 System timer error The timer test failed. Requires repair of the system board.
0270 Real time clock error Real-Time Clock (RTC) fails BIOS hardware test. May require
board repair.
0271 Check date and time
settings
BIOS found date or time out of range and reset the RTC. May
require setting legal date (1991-2099).
Access Setup and check the values in the
System Time and
S ystem Date fields of the Main menu.
0280 Previous boot
incomplete – Default
configuration used
Initial bootup failed. BIOS automatically loads the default system
values, and then boots again.
0281 Memory size found by
POST differed from
CMOS
The user added or removed a memory module, thus the system
memory size is different from the previous bootup value.
02F5 DMA test failed The DMA control test failed.
02F6 Software NMI failed An NMI signal is detected and/or user has pressed the NMI
switch.
POST beep codes
There are several POST routines that issue a POST terminal error and shut down the system if they fail.
Before shutting down the system, the terminal-error handler issues a beep code signifying the test
point error, writes the error to port 80h, attempts to initialize the video, and writes the error in the
upper left corner of the screen (using both mono and color adapters).
The POST routines cannot display messages when an error occurs if any of the following are present:
•
The error occurs before the video display is initialized.
•
The video configuration fails, either there’s no graphics card installed or the one installed is
faulty.
•
An external ROM module does not properly checksum to zero.
•
The system memory cannot be initialized.
During these instances the server unit emits a buzzing sound followed by a series of audible beeps.
An external ROM module (e.g. VGA) can also issue audible errors, usually consisting of one long
tone followed by a series of short tones. If you get a blank screen on boot, but hear beeps, count the
beeps and refer to the following table for their corresponding meaning. If you miss the beep code:
1. Turn off the server by pressing the power button for five seconds or more.
2. Restart the server by pressing the power button.
3. Listen for the signal again.
