Type [Auto]
Select [Auto] to automatically detect an IDE hard disk drive. If automatic detection
is successful, Setup automatically fills in the correct values for the remaining fields
on this sub-menu. If automatic detection fails, this may be because the hard disk
drive is too old or too new. If the hard disk was already formatted on an older
system, Setup may detect incorrect parameters. In these cases, select [User Type
HDD] to manually enter the IDE hard disk drive parameters. Refer to the next
section for details.
Before attempting to configure a hard disk drive, make sure you have the
correct configuration information supplied by the drive manufacturer. Incorrect
settings may cause the system to fail to recognize the installed hard disk.
[User Type HDD]
Manually enter the number of cylinders, heads and sectors per track for the drive.
Refer to the drive documentation or on the drive label for this information.
