DESCRIPTION

     The wdc driver provides the basic functions for the wd and atapi drivers.
     This driver supports IDE and EIDE controllers, as well as MFM, RLL and
     ESDI on the ISA bus. PCI IDE controllers in legaty mode are also support-
     ed, but the pciide(4) driver may provide more functionalities.

     For the ISA front-end, the 0x01 flag enables the 32 bits I/O negociation
     in the driver. This is known to cause problems with some motherboards.
