[User] Select "User" if you want to define the hard disk drive. You also
need to configure the other options, for example, Cylinder, Heads,
Sectors/Track, or other properties of the hard disk drive.
[Auto] The parameters that you can select here are usually stored on the
respective IDE drive. The 'Auto' setting in the 'Type' field means
that these values are automatically read from the drive and written
to memory.
If Type is selected for a drive that cannot be detected, a time-out is
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.

Sector Transfers." The value depends on the drive and should be set only to "Auto" in
the "Type" field.
