NEC Express5800/120Rd-2 Service Manual page 87

The POWER lamp on the front of the server comes on.
In a few seconds, the NEC logo appears on the screen and the Power On Self-Test
(POST) begins.
POST runs automatically when you power on or reset the server (Ctrl + Alt + Delete).
POST runs diagnostics, initializes the server, sets interrupt vectors, detects installed
peripheral devices, and boots up the operating system (if installed).
If the server halts before completing POST, POST emits a beep code indicating a fatal
system error requiring immediate attention. (See Chapter 6, "Troubleshooting," for
troubleshooting information.)
During the memory test, POST displays the amount of memory it was able to access and
test. Depending on the amount of installed memory, it may take several minutes to
complete the memory test.
NOTE: The factory default setting displays the NEC logo screen at
startup. During startup you can change the NEC logo screen to the POST
messages screen by pressing Esc. To change the start-up screen, use the
BIOS setup utility, "SETUP." (See Chapter 3 for details.)
During POST, you will see a message prompting you to launch the BIOS SETUP utility.
Start the BIOS SETUP utility appropriate to your system environment to change the BIOS setup.
For the BIOS SETUP settings for your server, see Chapter 3. For BIOS SETUP for the option
board, refer to the manual that comes with the option board.
