6 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 one of except the messages marked below with an asterisk (*), write down the message and contact Panasonic Technical Support. 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 fixed-disk type is correctly identified. 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 memory not working or not configured properly at offset 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 Panasonic Technical Support. 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.
