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
driver may provide more functionality.
For the isa(4) front-end, setting
flags to 0x01
enables 32-bit I/O negotiation. This is known to cause problems with some
atapiscsi(4), intro(4), isa(4), isapnp(4), macobio(4), obio(4), pciide(4), pcmcia(4), scsi(4), wd(4)
