3. Make sure your video display monitor and keyboard are
correctly connected to the system. Turn on the video
monitor. Set its brightness and contrast controls to at
least two-thirds of their maximum ranges (refer to the
documentation supplied with your video display
monitor).
4. If the operating system normally loads from the hard
disk drive, make sure there is no diskette in drive A.
Otherwise, place a diskette containing the operating
system files in drive A.
5. Turn on the system. If the power indicator LED does not
light, refer to "Power Light Does Not Light" found later in
this chapter.

Monitoring POST

Each time you turn on the system, the Power-On Self-Test
(POST) runs automatically and checks the system board,
processor board, memory, keyboard, and most installed
peripheral devices.
During the memory test, POST displays the amount of
memory that it is able to access and test. Depending on the
amount of memory, it may take several minutes to
complete the memory test.
Press F2 to enter SETUP. If you do not press F2, the above
message remains for a few seconds and the boot process
continues.
If POST finds an error, it displays an error message and, in
case there is a problem with the display, puts out a series
of long and short beeps. Write down any beep code emitted.
This information is useful to your service representative.
Refer to the "BIOS User's Information" section in this
chapter for a list of items to check for each error code and
for an explanation of the error beep codes.
