PDCIDE(4)                  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 controllers, 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 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.

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.
