The DEVICE CONFIGURATION IDENTIFY command returns a 512 byte data structure via PIO data-in transfer. 
The content of this data structure indicates the selectable commands, modes, and feature sets that the device is 
capable of supporting. If a DEVICE CONFIGURATION SET command has been issued reducing the 
capabilities, the response to an IDENTIFY DEVICE or IDENTIFY PACKET DEVICE command will reflect the 
reduced set of capabilities, while the DEVICE CONFIGURATION IDENTIFY command will reflect the entire set 
of selectable capabilities. 
 
The format of the Device Configuration Overlay data structure is shown in Table 11.8-8.
