POST Error Pause Option
For POST error(s) that are listed as Pause, the BIOS enters the error manager and waits
for the user to press an appropriate key before booting the operating system or entering
BIOS Setup.
The user can override this option by setting POST Error Pause to disabled in the BIOS
Setup utility Main menu page. If POST Error Pause is set to disabled, the system will
boot the operating system without user-intervention. The default value is set to enabled.
Diagnostic LEDs
During the system boot process, 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 will display 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, the diagnostic LEDs can be
used to identify the last POST process to be executed.
Figure 179: Diagnostic LEDs (A)
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.
