or correct the error.
Table 3-5. POST Messages
Message Description

0212 Keyboard Controller Failed
Keyboard controller failed the test. Might require replacing the motherboard (contains the
keyboard controller).
0213 Keyboard locked – Unlock key switch
Unlock the system to proceed.
0220 Monitor type does not match CMOS – Run SETUP
Monitor type is not correctly identified in BIOS Setup.
0230 Shadow RAM Failed at offset: nnnn
Shadow RAM failed at offset nnnn of the 64k block at which the error was detected.
0231 System RAM Failed at offset: nnnn
System RAM failed at offset nnnn of the 64k block at which the error was detected.
0232 Extended RAM Failed at offset: nnnn
Extended memory is not working or not configured properly at offset nnnn. Update to the
latest BIOS version.
0250 System battery is dead – Replace and run SETUP
CMOS clock battery indicator shows that the CMOS battery is dead. Connect the AC adapter
for at least 24 hours, then run BIOS 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 that
changes CMOS data. In response, the BIOS has installed the default Setup values. Use BIOS
Setup to modify these values if needed. If the error persists, check the system battery.
Connect the AC adapter for at least 24 hours; replace the motherboard.
0260 System timer error
Timer test failed. Replace the motherboard.
0270 Real time clock error
Real-time clock failed the BIOS test. Might require replacing the motherboard.
0271 Check date and time settings
BIOS found the date or time to be out of range, and reset the real-time clock. You might need
to use BIOS Setup to reset the legal date.
0280 Previous boot incomplete – Default configuration used
Previous POST did not complete successfully. POST loads default values and offers to run
BIOS Setup. If the failure was caused by incorrect values that are not corrected, the next boot
will likely fail. 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 that specified in CMOS.
02B0 Diskette drive A error
Drive A: is present but fails the BIOS POST diskette tests. Make sure the drive is defined with
the proper diskette type in BIOS Setup and that the drive is connected correctly.
02B2 Incorrect Drive A type – run SETUP
Type of floppy drive A: not correctly identified in BIOS Setup.
02D0 System cache error – Cache disabled
RAM cache failed and BIOS disabled the cache. May require replacing the motherboard.
A disabled cache slows system performance considerably.
02F0: CPU ID:
