3 Troubleshooting my computer66
*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 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.
