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

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.

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

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.

POST differed from CMOS Memory size found by POST differed from
CMOS.
