BIOS POST Codes
B.1 Power-On Self-Test (POST)
The system BIOS provides a rudimentary power-on self-test. The basic devices
required for the server to operate are checked, memory is tested, the LSI 1064 disk
controller and attached disks are probed and enumerated, and the two Intel dual-
gigabit Ethernet controllers are initialized.
The progress of the self-test is indicated by a series of POST codes.
These codes are displayed at the bottom right corner of the system’s VGA screen
(once the self-test has progressed far enough to initialize the video monitor).
However, the codes are displayed as the self-test runs and scroll off of the screen too
quickly to be read. An alternate method of displaying the POST codes is to redirect
the output of the console to a serial port (see Section B.1.2, “Redirecting Console
Output” on page B-2).
The message, BMC Responding is displayed at the end of POST.
