Acer R700 manual Power-On Self-Test Post, Operating System not found

51

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.

1Turn on your video monitor and system. After a few seconds, POST begins to run and displays a splash screen.

2While 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).

3After 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.

4If 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”

5At 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.
