Extended Properties Sheet

The presence of this sheet tells that the disk may be accessed with extended
BIOS functions. It shows the following information:

• Physical hard disk geometry (it does not necessarily match the geometry

reported by function 8). Here it does not have much practical value since
extended functions work with absolute sector numbers.

• The hard disk size in sectors. This is the most interesting parameter on

this sheet.

• Sector size. For all the usual hard disk this parameter is equal to 512.
• Various additional information.

7.8.4

interface parameters for this hard disk.
