Description
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.
The timer test failed. Requires repair of system
board.
Real-Time Clock fails BIOS hardware test. May
require board repair.
BIOS found date or time out of range and reset
the Real-Time Clock. May require setting legal
date (1991-2099).
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
states
, improper Setup settings can also
terminate POST and cause this error on the next
boot. Run Setup and verify that the waitstate
configuration is correct. This error is cleared the
next time the system is booted.
Memory size found by POST differed from
CMOS.
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.
Type of floppy drive A: not correctly identified in
Setup.
Type of floppy drive B: not correctly identified in
Setup.
