Verifying the condition of the storage devices
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 blue briefly. Check the activity
indicators for the hard drive(s), DVD-ROM drive, and any other 5.25"
device you may have installed.
If any of these indicators fail to light up, refer to related problems listed
in the Specific problems and corrective actions section.
Confirming loading of the operating system

operating system prompt does not appear, see
