.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
2000-03-01 19:28:34 +03:00
and ESDI on the ISA bus. PCI IDE controllers in legacy mode are also supported,
but the
.Xr pciide 4
2000-10-05 16:31:15 +04:00
driver may provide more functionality.
.Pp
For the ISA front-end, the 0x01 flag enables 32-bit I/O negotiation in
1999-05-19 18:41:54 +04:00
the driver. This is known to cause problems with some motherboards.
