PDCIDE(4) BSD Kernel Interfaces Manual PDCIDE(4)
pdcide -- Promise IDE disk controllers driver
pdcide* at pci? dev ? function ? flags 0x0000
The pdcide driver supports the Promise Ultra33, Ultra66, Ultra100, Ultra100TX2,
Ultra100TX2v2, Ultra133, Ultra133TX2, Ultra133TX2v2, Fasttrak133 and Serial ATA/150 IDE con-
trollers, and provides the interface with the hardware for the ata(4) driver.
The 0x0002 flag forces the pdcide driver to disable DMA on chipsets for which DMA would nor-
mally 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 30 or 33 MHz. This driver may not work properly on overclocked systems.
The pdcide driver does NOT function correctly on NetBSD/sparc64.
