This driver supports IDE and EIDE controllers, as well as MFM, RLL 57and ESDI on the ISA bus. PCI IDE controllers in legacy mode are also supported, 58but the 59.Xr pciide 4 60driver may provide more functionality. 61.Pp 62On the ISA front-end, the following flags are supported: 63.Bl -tag -compact -width "0x0000" -offset "xxxx" 64.It 0x0001 65Enables 32-bit I/O negotiation in the driver. This is known to cause 66problems with some motherboards. 67.It 0x0002 68Don't probe for the second drive. 69.It 0x0004 70Set WDC_CAPABILITY_ATA_NOSTREAM flag. 71.It 0x0008 72Set WDC_CAPABILITY_ATAPI_NOSTREAM flag. 73.El 74.Sh SEE ALSO 75.Xr ata 4 , 76.Xr atapi 4 , 77.Xr intro 4 , 78.Xr isa 4 , 79.Xr isapnp 4 , 80.Xr mainbus 4 , 81.Xr ofisa 4 , 82.Xr pciide 4 , 83.Xr pcmcia 4 , 84.Xr scsi 4 , 85.Xr wd 4 86
