The Device Configuration Set command allows a device manufacturer or a PC manufacturer to reduce the set of
optional commands, modes, or f eature sets supported by a device as indicated by a Device Configuration Identify
command. The Device Configuration Set Command transfers an overlay that modifies some of the bits in words
63, 82, 83, 84, and 88 of th e Identify Device command. When the bits in these word s are cleared, the device shall
no longer support the indicated command, mode, or feature set. If a bit is set in the overlay transmitted by the
device that is not set in the overlay received from a Device Configuration Identify command, then no action is
taken for that bit. Modifying the maximum LBA of the d evice also changes the address value returned by a Read
Native Max Address, or Read Native Max Address Ext command.
