The Device Configuration Set command allows a device manufacturer or a PC manufacturer to reduce the set of optional commands, modes, or feature 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 the Identify Device command. When the bits in these words 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 device also changes the address value returned by a Read Native Max Address, or Read Native Max Address Ext command.
