List of Error Codes
The following is a list of the messages that BIOS can display. Most of them occur during POST. Some of them display
information about a hardware device, e.g., the amount of memory installed. Others may indicate a problem with a device,
such as the way it has been configured. Following the list are explanations of the messages and remedies for reported
problems.
If your system displays any of the below error messages other that the ones marked with an asterisk (*), write down the
message and contact your technical support office. If your system fails after you make changes in the Setup menus, reset
the computer, enter Setup and install Setup defaults or correct the error.

0250 System battery is dead - Replace and run SETUP
The CMOS clock battery indicator shows the battery is dead. Replace the battery and run Setup to reconfigure the
system.
*0251 System CMOS checksum bad - Default configuration used
System CMOS has been corrupted or modified incorrectly, perhaps by an application program that changes data stored
in CMOS. The BIOS installed Default SETUP Values. If you do not want these values, enter Setup and enter your own
values. If the error persists, check the system battery or contact your technical support office.
0260 System timer error
The timer test failed. Requires repair of system board.
0270 Real time clock error
Real-time clock fails BIOS test. May require board repair.
*0280 Previous boot incomplete - Default configuration used
Previous POST did not complete successfully. POST loads default values and offers to run Setup. If the failure was
caused by incorrect values and they are not corrected, the next boot will likely fail. On systems with control of
wait
states
, improper Setup settings can also terminate POST and cause this error on the next boot. Run Setup and verify
that the wait-state configuration is correct. This error is cleared the next time the system is booted.
0281 Memory Size found by POST differed from EISA CMOS
Memory size found by POST differed from EISA CMOS.
