INITIALIZE DEVICE PARAMETERS (X '91')
The host system can set the number of sectors per track and the maximum head
number (maximum head number is "number of heads minus 1") per cylinder with
this command. Upon receipt of this command, the device sets the parameters.
Then the device reports the status to the host system.
When the SC field is specified to X '00', an ABORTED COMMAND error is
posted. Other than X '00' is specified, this command terminates normally.
The parameters set by this command are retained even after soft reset and
COMRESET issuance or power save operation regardless of the setting of
disabling the reverting to default setting.
The operation is always performed in CHS mode, with the command ignoring any
setting of LBA mode.
