Verifying Proper Operation of Key System Indicators

As POST determines the system configuration, it tests for the presence
of each mass storage device installed in the system. As each device is
checked, its activity indicator should turn on briefly. Check for the
following:
T
Does the diskette drive activity indicator turn on briefly. If not, refer
to "Diskette Drive Activity Indicator Does Not Light" in this chapter.
T
If a second diskette drive is installed, does its activity indicator turn
on briefly. If not, refer to "Diskette Drive Activity Indicator Does Not
Light" in this chapter.
T
If there is a hard disk drive or SCSI devices installed in the system,
does the hard disk drive activity indicator turn on briefly. If not, refer
to "Hard Disk Drive Activity Indicator Does Not Light" in this chapter.

Confirming Loading of the Operating System

Once the system boots up, the operating system prompt appears on the
screen. The prompt varies according to the operating system. If the
operating system prompt does not appear, refer to "Problems with
Application Software" found later in this chapter.
