Changes
/* Accessing the FDC 765 */
* Result Phase : Returns up to 7 result bytes (depending on the command) that are containing status information. The Recalibrate and Seek Track commands do not return result bytes directly, instead the program must wait until the Main Status Register signalizes that the command has been completed, and then it must (!) send a Sense Interrupt State command to 'terminate' the Seek/Recalibrate command.
During the result phase, all the result bytes must be read. The FDC will not accept a new command until all the result bytes are read.
The Main Status Register signalizes when the FDC is ready to send/receive the next byte through the Data Register.
