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 length of 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 a splash screen is displayed.
2. While the splash screen is displayed, you can either:
• Press <F2> to enter the BIOS Setup (see “Using BIOS Setup” on page 38)
OR
• press <Esc> to change the boot device priority for this boot only (see “Changing
the Boot Device Priority Temporarily” on page 63).

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

searches all removable devices in the order defined by the boot priority.
