Monitoring POST while it is running
Each time you turn on the system, the power-on self-
test (POST) runs automatically and checks the system
board, CPU, 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. When the memory test
completes, the following is displayed:
Press F2 key if you want to run SETUP
If you do not press <F2>, the above message remains
for a few seconds and the boot process continues.
When this message appears:
Press <Ctrl><A> for SCSISelect™ Utility!
Press <Ctrl+A> if you have installed SCSI devices in
your system. When the utility appears, follow the
instructions on your monitor to configure the SCSI host
adapter settings and run the SCSI disk utilities. See
Chapter 4, Configuring Your System.
If you choose not to run the SCSISelect Utility, 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.
Table 6-1 lists keys active during POST and provides a
description of errors that may occur.
