.Sh DESCRIPTION
The
.Nm
driver provides the interface with the hardware for the
.Xr ata 4
driver. 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
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
Set WDC_CAPABILITY_ATA_NOSTREAM flag.
.It 0x0008
Set WDC_CAPABILITY_ATAPI_NOSTREAM flag.
