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 ( page 32). 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.
0200 Failure Fixed Disk
Fixed disk in not working or not configured properly. Check to see if fixed disk is attached properly. Run Setup. Find out if the
0210 Stuck key
Stuck key on keyboard.
0211 Keyboard error
Keyboard not working.
0212 Keyboard Controller Failed
Keyboard controller failed test. May require replacing keyboard controller.
0213 Keyboard locked - Unlock key switch Unlock the system to proceed.
0230 System RAM Failed at offset : nnnn
System RAM failed at offset nnnn of in the 64k block at which the error was detected.
0231 Shadow RAM Failed at offset : nnnn
Shadow RAM failed at offset nnnn of the 64k block at which the error was detected.
0232 Extended RAM Failed at offset : nnnn Extended RAM Failed at address line : nnnn
Extended memory not working or not configured properly at offset or address nnnn.
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 ( page 32).
0260 System timer error
The timer test failed. Requires repair of system board.
0270 Real time clock error
*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
0281 Memory Size found by POST differed from EISA CMOS Memory size found by POST differed from EISA CMOS.
02B0 Diskette drive A error
02B1 Diskette drive B error
Drive A: or B: is present but fails the BIOS POST diskette tests. Check to see that the drive is defined with the proper diskette type in Setup and that the diskette drive is attached correctly.
02B2 Incorrect Drive A type - run SETUP
Type of floppy drive A: not correctly identified in Setup.
02B3 Incorrect Drive B type - run SETUP
Type of floppy drive B: not correctly identified in Setup.
02D0 System cache error - Cache disabled Contact your technical support office ( page 32).
02F0: CPU ID:
