In - effect, it's identical to PATA hardware reset. Note that - this can be done with the standard SCR Control register. - As such, it's usually easier to implement than software - reset. - - - - - - - - One more thing to consider when resetting devices is that - resetting clears certain configuration parameters and they - need to be set to their previous or newly adjusted values - after reset. - - - - Parameters affected are. - - - - - - - CHS set up with INITIALIZE DEVICE PARAMETERS (seldomly used) - - - - - - Parameters set with SET FEATURES including transfer mode setting - - - - - - Block count set with SET MULTIPLE MODE - - - - - - Other parameters (SET MAX, MEDIA LOCK...) - - - - - - - ATA/ATAPI standard specifies that some parameters must be - maintained across hardware or software reset, but doesn't - strictly specify all of them.
