DESCRIPTION
The wdc driver provides the basic functions for the wd(4) and atapi(4)
drivers. This driver 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 front-end, the 0x01 flag enables 32-bit I/O negotiation in
the driver. This is known to cause problems with some motherboards.
