A Error Messages and Indicators

Desktop Board DQ35JO reports POST errors in two ways:
• By sounding a beep code
• By displaying an error message on the monitor

BIOS Beep Codes

The BIOS also issues a beep code (one long tone followed by two short tones) during
POST if the video configuration fails (a faulty video card or no card installed) or if an
external ROM module does not properly checksum to zero. Table 15 lists the BIOS
codes.

BIOS Error Messages

When a recoverable error occurs during the POST, the BIOS displays an error message
describing the problem. Table 16 gives an explanation of the BIOS error messages.

Explanation
Processor was previously shutdown due to a thermal event
(overheating).
The firmware has detected that a Multi-Bit ECC Error occurred.
The firmware has detected that a Single-Bit ECC Error occurred.
The firmware has detected that a CMOS battery failure occurred.
The firmware has detected that a CMOS Checksum Error occurred.
The firmware has detected that the system date/time has not
been set.
The firmware has detected that the system memory has
decreased.
The system chassis was opened.
SERIAL PRESENCE DETECT (SPD) device data missing or
inconclusive. Properly programmed SPD device data is required
for reliable operation.
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.
