optiide
— OPTi IDE
disk controllers driver
optiide* at pci? dev ? function ? flags
0x0000
The optiide
driver supports the OPTi
82c621, 82c568 and 82d568 IDE controllers, and provides the interface with
the hardware for the ata(4)
driver.
The 0x0002 flag forces the optiide
driver
to disable DMA on chipsets for which DMA would normally be enabled. This can
be used as a debugging aid, or to work around problems where the IDE
controller is wired up to the system incorrectly.
ata(4), atapi(4), intro(4), pci(4), pciide(4), wd(4), wdc(4)
The timings used for the PIO and DMA modes for controllers listed above are for a PCI bus running at 25 or 33 MHz. This driver may not work properly on overclocked systems.
