A Error Messages and Indicators

Desktop Board D975XBX reports POST errors in two ways:

By sounding a beep code

By displaying an error message on the monitor

BIOS Beep Codes

The BIOS beep codes are listed in Table 10. The BIOS also issues a beep code (one long tone followed by two short tones) during POST if the video configuration fails (a faulty graphics card or no card installed) or if an external ROM module does not properly checksum to zero.

Error Message

Explanation

 

 

PROCESSOR_THERMAL_TRIP_ERROR

CPU was previously shutdown due to a thermal event

 

(overheating).

 

 

MULTI_BIT_ECC_ERROR

The firmware has detected that a Multi-Bit ECC Error occurred.

 

 

SINGLE_BIT_ECC_ERROR

The firmware has detected that a Single-Bit ECC Error occurred.

 

 

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. DDR2 533 MHz memory assumed at

 

slowest timings.

 

 

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.
