My PC configuration:
No SCSI device is present.
Primary IDE channel (reported as host adapter 0):
master is hard drive (reported as TargetId 0, LUN 0)
slave is not present
Secondary IDE channel (reported as host adapter 1):
master is hard drive (reported as TargetId 0, LUN 0)
slave is IDE CDROM (reported as TargetId 1, LUN 0)
