Setting this parameter also sets the Cylinder, Head, Sector, and Size
parameters.
Cylinders
This parameter specifies the number of cylinders of your hard disk,
and is automatically set depending on your Type parameter setting.
Heads
This parameter specifies the number of heads of your hard disk, and is
automatically set depending on your Type parameter setting.

is automatically set depending on your Type parameter setting.
Size

Enhanced IDE Features
Hard Disk Size > 504 MB
When set to Auto , the BIOS utility automatically detects if the installed
hard disk supports the function. If supported, it allows you to use a
hard disk with a capacity of more than 504 MB. This is made possible
through the Logical Block Address (LBA) mode translation. However,
this enhanced IDE feature works only under DOS, Windows 3.x,
Windows 95, and Windows NT 3.5 and above. Other operating
systems require this parameter to be set to
Disabled .
