Power-on Self Test (POST)
Each time you turn on the system, POST starts running. POST checks the baseboard, 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.
1. Turn on your video monitor and 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 do NOT have a 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
(To create software installation diskettes, see the printed Quick Start Guide.)
If you do not press <F2>, 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 77. 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.
After POST completes, the system beeps once.
What appears on the screen after this depends on if you have an OS loaded and if so, which one.
If the system halts before POST completes running, it emits a beep code indicating a critical
system error that requires immediate attention. If POST can display a message on the video
display screen, the speaker beeps twice as the message appears.
Note the screen display and write down the beep code you hear; this information is useful for your
service representative. For a listing of beep codes and error messages that POST can generate, see
Chapter 7, “Solving Problems,” beginning on page 123.
