Before video initialization, POST error codes are logged in the event log. 6.3.1 Diagnostic LEDs During the system boot process, the BIOS executes several platform configuration processes, each of which is assigned a specific hex POST code number. As each configuration routine is started, the BIOS displays the POST code on the POST code diagnostic LEDs found on the back edge of the server board. To assist in troubleshooting a system hang during the POST process, you can use the diagnostic LEDs to identify the last POST process to be executed. Each POST code is represented by a combination of colors from the four LEDs. The LEDs are capable of displaying three colors: green, red, and amber. The POST codes are divided into an upper nibble and a lower nibble. Each bit in the upper nibble is represented by a red LED and each bit in the lower nibble is represented by a green LED. If both bits are set in the upper and lower nibbles then both red and green LEDs are lit, resulting in an amber color. If both bits are clear, then the LED is off. In the following example, the BIOS sends a value of ACh to the diagnostic LED decoder. The LEDs are decoded as follows: ƒ Red bits = 1010b = Ah ƒ Green bits = 1100b = Ch Revision 1.3 97 Intel order number E15331-006

Error Messages and Error Codes

The system BIOS displays POST error codes and error messages on the video screen. Before

video initialization, POST error codes are logged in the event log.

6.3.1

Diagnostic LEDs

During the system boot process, the BIOS executes several platform configuration processes,

each of which is assigned a specific hex POST code number. As each configuration routine is

started, the BIOS displays the POST code on the POST code diagnostic LEDs found on the

back edge of the server board. To assist in troubleshooting a system hang during the POST

process, you can use the diagnostic LEDs to identify the last POST process to be executed.

Each POST code is represented by a combination of colors from the four LEDs. The LEDs are

capable of displaying three colors: green, red, and amber. The POST codes are divided into an

upper nibble and a lower nibble. Each bit in the upper nibble is represented by a red LED and

each bit in the lower nibble is represented by a green LED. If both bits are set in the upper and

lower nibbles then both red and green LEDs are lit, resulting in an amber color. If both bits are

clear, then the LED is off.

In the following example, the BIOS sends a value of ACh to the diagnostic LED decoder. The

LEDs are decoded as follows:

Red bits = 1010b = Ah

Green bits = 1100b = Ch
