Access for the device is shortened with "Cylinder Head Sector
(Addressing) "having 0 to 1023 cylinders, 0 to 15 heads and 0
to 63 sectors.
Shortened with the Logical Block Addressing Method, the
entire memory area is divided into access units and those serial
numbers are used for accessing.
This is the access method for extended CHS. When the number
of CHS cylinders exceeds the normal amount of 1024 cylinders,
the address is not accessible so the CHS is extended.
BIOS determines the optimum method based on the
information obtained by the device. The LBA method is
normally used.
