[User]
Select “User” to enter a user-specific definition of the hard disk
type. Configure all the other options, for example, Cylinder, Heads,
Sectors/Track, or other properties of the hard disk drive.
[Auto]
The parameters which you can select in this dialog are usually
saved to 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 does not exist, a timeout is
triggered within approximately 1 minute and the entries remain
unchanged. It makes sense only to set "Auto" for interfaces to
which a drive is connected.
