The BIOS indicates errors by writing an error code to
the PS/2-standard logging area in the Extended BIOS
Data Area, and by displaying a message on the screen,
which is sometimes preceded by the POST Error Code.
The error code will also be logged to the Event Logging
area.
Report any error code to your service representative.
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 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.
■
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.
