NetBSD 6.1.5 - man page for pdcide (netbsd section 4)

PDCIDE(4)			   BSD Kernel Interfaces Manual 			PDCIDE(4)

NAME
     pdcide -- Promise IDE disk controllers driver

SYNOPSIS
     pdcide* at pci? dev ? function ? flags 0x0000

DESCRIPTION
     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.

SEE ALSO
     ata(4), atapi(4), intro(4), pci(4), pciide(4), wd(4), wdc(4)

BUGS
     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.
