Description
keyboard controller.
Unlock the system to proceed.
Monitor type not correctly identified in Setup.
Shadow RAM failed at offset nnnn of the 64k block at which
the error was detected.
System RAM failed at offset nnnn of in the 64k block at
which the error was detected.
Extended memory not working or not configured properly at
offset nnnn.
The CMOS clock battery indicator shows the battery is dead.
Replace the battery and run Setup to reconfigure the system.
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.
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 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.
Memory size found by POST differed from CMOS.
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.
