When a recoverable error occurs during the POST, the BIOS displays an error message
describing the problem.
Table 20 gives an explanation of the BIOS error messages.
Table 20. BIOS Error Messages
Error Message
Explanation
PROCESSOR_THERMAL_TRIP_ERROR
Processor was previously shutdown due to a thermal
event (overheating).
CMOS_BATTERY_ERROR
The firmware has detected that a CMOS battery failure
occurred.
CMOS_CHECKSUM_ERROR
The firmware has detected that a CMOS Checksum Error
occurred.
CMOS_TIMER_ERROR
The firmware has detected that the system date/time
has not been set.
MEMORY_SIZE_DECREASE_ERROR
The firmware has detected that the system memory has
decreased.
INTRUDER_DETECTION_ERROR
The system chassis was opened.
SPD_TOLER_ERROR
SERIAL PRESENCE DETECT (SPD) device data missing or
inconclusive.
Properly programmed SPD device data is
required for reliable operation.
MEM_OPTIMAL_ERROR
The installed amount of memory in Channel A is not
equal to the amount of memory in Channel B.
Maximum
memory performance is achieved with equal amounts of
memory installed in each channel.
