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:
!
Does the diskette drive activity indicator turn on briefly? If not, refer to “Diskette
Drive Activity Indicator Does Not Light”
in this chapter.
!
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.
