Power-On Self-Test (POST)

Each time you turn on the system the BIOS begins execution of the 
Power-On Self-Test (POST). POST discovers, configures, and tests the 
processors, memory, keyboard, and most installed peripheral devices. 
The time needed to test memory depends on the amount of memory 
installed. POST is stored in flash memory.

1

Turn on your video monitor and system. After a few seconds, POST 
begins to run and displays a splash screen.

2

While the splash screen is displayed:

•

Press <F2> to enter the BIOS Setup (see “BIOS Setup”)

OR

•

Press <Esc> to view POST diagnostic messages and change the 
boot device priority for this boot only (see “Temporarily 
Changing the Boot Device Priority” on page 52).

3

After pressing <F2> or <Esc> during POST, you can press <Ctrl+A> 
to run the SCSISelect Utility. For more information, see“Running 
the Adaptec SCSISelect Utility” on page 54.

4

If you do not press <F2> or <Esc> and do NOT have a device with 
an operating system loaded, the boot process continues and the 
system beeps once. The following message is displayed:

“Operating System not found”

5

At this time, pressing any key causes the system to attempt a 
reboot. The system searches all removable devices in the order 
defined by the boot priority.
