2-18 General Description

POST Execution Flow

The following describes the progress of POST in the chronological order.

IMPORTANT:

„Do not power off the server while POST is in progress.

„Do not make key entries or perform mouse operations while POST is in progress.

„Some system configurations may display the message "Press Any Key" to prompt a key entry. This message is driven by BIOS of an installed optional board. Make sure to read the manual that comes with the optional board before any key entry.

„Powering on the server, after you installed or removed an optional PCI board or moved it to another slot, may display the message that indicates incorrect board configuration and suspend POST.

In such a case, press F1 to continue POST. 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 takes a few minutes to complete depending on the memory size of the server. Also, it may take approximately one minute for the screen display to appear after rebooting the server.

2.Some messages appear upon completion of the memory check. These messages appear to indicate that the system has detected the CPU, keyboard, and mouse.

3.After a few seconds, POST displays the following message prompting you to launch the BIOS SETUP utility, stored in the system memory of the server. This message appears at bottom left on the screen.

Press <F2> to enter SETUP or Press <F12> to boot from Network

Launch the BIOS setup utility when you need to change the settings to meet the requirements for the server. As long as the above message is not displayed with an error message, you don't have to launch the utility. (Ignore the message. POST will automatically proceed.)

To launch the BIOS setup utility, press F2 while the above message is displayed. See Chapter 4 for setup and parameters.

The server automatically restarts POST all over again when you exit the SETUP utility.

4.If your server uses onboard SAS RAID feature, the following message is displayed on the screen to prompt you to run the utility.

Press Ctrl-M to run LSI Logic Software RAID Setup Utility

Press Ctrl + M to run the utility. For detail explanation, see Chapter 4 for detail.
