means both the device and head parameters are used, Y means both device and other bits.
D Only the drive parameter is valid and not the head parameter.
d The device parameter is valid; the usage of the head parameter is vendor-specific.
D* Address to Device 0, but both devices execute it.
*1 Smart Enable/Disable Auto-save.
