.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides the basic functions for the
|
|
.Xr wd 4
|
|
and
|
|
.Xr 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
|
|
.Xr pciide 4
|
|
<<<<<<< wdc.4
|
|
driver may provide more functionaliy.
|
|
.Pp
|
|
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.
