The wdc
driver provides the interface with the hardware
for the ata(4) driver. 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
pciide(4) driver may provide
more functionality.
On the ISA front-end, the following flags are supported:
- 0x0001
- Enables 32-bit I/O negotiation in the driver. This is known to cause
problems with some motherboards.
- 0x0002
- Don't probe for the second drive.
- 0x0004
- Set WDC_CAPABILITY_ATA_NOSTREAM flag.
- 0x0008
- Set WDC_CAPABILITY_ATAPI_NOSTREAM flag.
