-/// El Torito Volume Descriptor\r
-/// Note that the CDROM_VOLUME_DESCRIPTOR does not match the ISO-9660\r
-/// descriptor. For some reason descriptor used by El Torito is\r
-/// different, but they start the same. The El Torito descriptor\r
-/// is left shifted 1 byte starting with the SystemId. (Note this\r
-/// causes the field to get unaligned)\r
