  The flags can be specified on the line for the drive as a 16 bit int,
  or on the controller line as a 32 bit int, where the top 16 bit is
  relevant to the highest numbered drive.

+ .Em CMD640
+ enables a workaround for a deficiency of the CMD640b IDE controller.
+ If this option is enabled and the chip is detected by the PCI subsystem
+ the primary and secondary controller will not be used simultaneously.
