49 driver provides the interface with the hardware for the
51 driver. This driver supports IDE and EIDE controllers, as well as MFM, RLL
52 and ESDI on the ISA bus. PCI IDE controllers in legacy mode are also supported,
55 driver may provide more functionality.
57 On the ISA front-end, the following flags are supported:
58 .Bl -tag -compact -width "0x0000" -offset "xxxx"
60 Enables 32-bit I/O negotiation in the driver. This is known to cause
61 problems with some motherboards.
63 Don't probe for the second drive.
65 Set WDC_CAPABILITY_ATA_NOSTREAM flag.
67 Set WDC_CAPABILITY_ATAPI_NOSTREAM flag.
