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 dealer.
0260 System timer error* The timer test failed. Requires repair of system board.
0270 Real time clock error* Real-Time Clock fails BIOS hardware test. May require board
repair.
0271 Check date and time
settings
BIOS found date or time out of range and reset the Real-
Time Clock. May require setting legal date (1991-2099).
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.
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
RAM cache failed and BIOS disabled the cache. On older
boards, check the cache jumpers. You may have to replace
the cache. See your dealer. A disabled cache slows system
performance considerably.
