1-34 System Overview

POST Execution Flow

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

IMPORTANT:

!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 massage 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.A few seconds after 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 express 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, SETUP, stored in the system memory of the server. This message appears at bottom left on the screen.

Press <F2> to enter SETUP, Press <F12> to 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 SETUP utility, press F2 while the above message is displayed. See Chapter 3 for setup and parameters.

The server automatically restarts POST all over again when you exit the SETUP utility. Press F12 to start the operating system from the network drive.
