DESCRIPTION

     The wdc driver provides the basic functions for the wd(4) and
     atapiscsi(4) drivers. It supports IDE and EIDE controllers, as well as
     MFM, RLL, and ESDI on the ISA bus. PCI IDE controllers in legacy mode are
     also supported, but the pciide(4) driver may provide more functionality.

     For the isa(4) front-end, setting flags to 0x01 enables 32-bit I/O nego-
     tiation. This is known to cause problems with some motherboards.
