(11) 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 BSY bit of
Status register and saves the parameters. Then the device clears the BSY bit and
generates an interrupt.
When the SC register 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 reset or power save
operation regardless of the setting of disabling the reverting to default setting.
The device ignores the L bit specification and operates with only CHS mode
specification.
