Power-on Self Test

Each time you turn on the system, the power-on self test (POST) runs. POST checks the system board, processors, memory, keyboard, and most installed peripheral devices. During the memory test, POST displays the amount of memory it is able to access and test. The length of time needed to test memory depends on the amount of memory installed. POST is stored in flash memory.

To Use POST

1.Turn on the monitor and the system. After a few seconds, POST begins to run.

2.After the memory test, these screen prompts and messages appear:

Keyboard Detected Mouse Initialized

Press <F2> to enter Setup

3.If you do not press F2 and there is no device with an OS loaded, the above message remains for a few seconds while the boot process continues, and the system beeps once. Then this message appears:

Operating System not found

If you do not press F2 and do have a device with an OS loaded, the boot process continues and this message appears:

Press <Ctrl><C> to enter SCSI Utility

4.Press CTRL+C if SCSI devices are installed. When the utility opens, follow the displayed instructions to configure the onboard SCSI host adapter settings and to run the SCSI utilities. Also see “Using the Symbios SCSI Utility” on page 152. If you do not enter the SCSI utility, the boot process continues.

5.Press ESC during POST to access a boot menu when POST finishes. From this menu, you can choose the boot device or enter BIOS Setup.
