POST Execution Flow
The following describes in chronological order the progress of the POST.
IMPORTANT:
Do not power off the server while the POST is in progress.
Do not strike any key or perform any mouse operations while the POST is in progress.
Some system configurations may display the message "Press Any Key" to prompt a key
entry. This message is driven by the BIOS of an installed optional board. Make sure to
read the manual that comes with the optional board before striking any key.
If you installed or removed an optional PCI board or moved it to another slot, powering
on the server may display a message that indicates an incorrect board configuration and
suspend the POST.
In such a case, press F1 to continue the POST. The board configuration can be made
using the utility described later.
1. After a few seconds from power-on, POST starts checking the memory. The count message of the basic and
expansion memory appears at top left on the display unit screen. The memory check may take a few minutes
to complete depending on the size of the memory installed in the server. It may take approximately one
minute for the screen display to appear after rebooting the server.
2. Some messages appear upon the completion of the memory check. These messages indicate that the system
has detected the CPU, keyboard, and mouse.
3. After a while, the POST displays messages prompting you to launch the utilities for the LAN controllers on
the motherboard. You do need not to launch the utility. (Ignore the message. The POST will automatically
proceed.)
4. The POST detects the Internal RAID Controller, and displays the following message prompting you to launch
the WebBIOS Setup utility.
Press <Ctrl> <H> for WebBIOS
Press Ctrl + H on the POST screen to run WebBIOS. See Chapter 4 for setup and parameters.
When you exit from the utility, you are prompted to reboot the system. Press Ctrl + Alt + Delete. The server
restarts the POST all over again.
5. The POST displays the ID numbers of the SAS devices connected to the server.
