Flow Of Post - NEC Express5800 Series User Manual

2-24 General Description

Flow of POST

This section walks you through how POST is performed.
1.
When the system first powers on, only one CPU/IO module will start up.
POST will be performed on this CPU/IO module.
2.
Memory check starts.
A message appears at the upper left of the screen to show that the basic and expanded
memories are being counted. The memory check may take a few minutes to complete
depending on the server's memory size. Likewise, it may take about one minute for the
screen to appear when the server is rebooted.
3.
The server starts processor check, IO check, and initialization.
Several messages appear: they show the ID of the selected CPU/IO modules, information
on the processor, detection of the keyboard and mouse, etc.
4.
A message appears at the lower left of the screen, prompting for start up of the BIOS setup
utility "SETUP."
Press <F2> to enter SETUP
You will need to start it when you want to modify the CMOS configuration for the server.
Unless this message appears together with an error message, you do not need to start the
utility to modify the configuration. (If you wait for a few seconds, POST will go on
automatically.)
To start the SETUP utility, press F2 while the above message is displayed. For CMOS
setting see the section on BIOS setup.
When SETUP is completed, the server will reboot it self automatically and perform POST.
5.
A message appears prompting for startup of SAS BIOS setup utility.
When a built-in SAS controller is detected, a message will appear prompting for startup of
SAS BIOS setup utility. (After a few seconds POST automatically continue on.)
If you press Ctrl + A, the SAS BIOS setup utility will start. However, you usually do not
need to use the setup utility. For setting and parameter functions, see "SAS BIOS" (page
4-33).
When SETUP is complete, the server will reboot automatically and perform POST from
the start again.
6.
The screen shows the ID numbers of the connected disk drive.
7.
Upon completion of POST, the password entry screen appears prior to OS startup.
The password entry screen will appear after the normal termination of POST only if you
have set a password in the BIOS setup utility "SETUP."
You can enter a password up to three times. If you enter an incorrect password three
