Large: 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.
Auto: BIOS determines the optimum method based on the information
obtained by the device. The LBA method is normally used.
