need to configure the other options, for example, Cylinder, Heads,
Sectors/Track, or other properties of the hard disk drive.

respective IDE drive. The 'Auto' setting in the 'Type' field means
that these values are automatically read from the drive and written
to memory.

triggered within approximately 1 minute and the entries remain
unchanged. You should always check that the interfaces for which
you select 'Auto' are in fact connected to drives.
