This driver supports IDE and EIDE controllers, as well as MFM, RLL 59and ESDI on the ISA bus. PCI IDE controllers in legacy mode are also supported, 60but the 61.Xr pciide 4 62driver may provide more functionaliy. 63.Pp 64For the ISA front-end, the 0x01 flag enables 32-bit I/O negotiation in 65the driver. This is known to cause problems with some motherboards. 66.Sh SEE ALSO 67.Xr atapi 4 , 68.Xr intro 4 , 69.Xr pciide 4 , 70.Xr scsi 4 , 71.Xr wd 4 72
