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 property 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. 0271 Check date and time settings Real-time clock is illegal. Run Setup and set the date and clock. *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 CMOS Memory size found by POST differed from CMOS. 02D0 System cache error - Cache disabled 02D1 System Memory exceeds the CPU’s caching limit Contact Panasonic Technical Support. 19 Troubleshooting Troubleshooting List of Error Codes 02F5 DMA Test Failed Cannot write to extended DMA (Direct Memory Access) registers. 02 F6 Software NMI Failed Cannot generate software NMI (Non-Maskable Interrupt). 02F7 Fail - Safe Timer NMI Failed Fail-Safe Timer takes too long. device address Conflict Address conflict for specified device. Allocation Error for: device Run ISA or EISA Configuration Utility to resolve resource conflict for the specified device. Hardware Configuration changed The display appears when there is a change in the hardware. This display only occurs one time. Entering SETUP... Starting Setup Utility. Failing Bits : nnnn The hex number nnnn is a map of the bits at the RAM address which failed the memory test. Each 1 (one) in the map indicates a failed bit. See error 230,231 or 232 for offset address of the failure in System, Extended or Shadow memory. Fixed Disk n Fixed disk n (0-3) identified. Invalid System Configuration Data Problem with NVRAM (CMOS) data. I/O device IRQ conflict I/O device IRQ conflict error, PS/2 Mouse Boot Summary Screen: PS/2 Mouse installed. nnnn kB Extended RAM Passed Where nnnn is the amount of RAM in kilobytes successfully tested. nnnn Cache SRAM Passed Where nnnn is the amount of system cache in kilobytes successfully tested. nnnn kB Shadow RAM Passed Where nnnn is the amount of shadow RAM in kilobytes successfully tested. nnnn kB System RAM Passed Where nnnn is the amount of system RAM in kilobytes successfully tested. Operating System not found Operating system cannot be located on either drive A: or drive C:. Enter Setup and see if fixed disk and drive A: are properly identified. Parity Check 1 nnnn Parity error found in the system bus. BIOS attempts to locate the address and display it on the screen. If it cannot locate the address, it displays ????. Parity is a method for checking errors in binary data, A parity error indicates that some data has been corrupted. Parity Check 2 nnnn Parity error found in the I/O bus. BIOS attempts to locate the address and display it on the screen. If it cannot locate the address, it displays ????. Press to resume, to Setup Displayed after any recoverable error message. Press to start the boot process or to enter a Setup and change the settings. Write down and follow the information shown on the screen. Press to enter Setup Optional message displayed during P...
