.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
|
|
driver may provide more functionality.
|
|
.Pp
|
|
On the ISA front-end, the following flags are supported:
|
|
.Bl -tag -compact -width "0x0000" -offset "xxxx"
|
|
.It 0x0001
|
|
Enables 32-bit I/O negotiation in the driver. This is known to cause
|
|
problems with some motherboards.
|
|
.It 0x0002
|
|
Don't probe for the second drive.
|
|
.It 0x0004
