.Sh NAME
.Nm pdcide
.Nd Promise IDE disk controllers driver
.Sh SYNOPSIS
.Cd "pdcide* at pci? dev ? function ? flags 0x0000"
.Sh DESCRIPTION
The
.Nm
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
.Xr ata 4
driver.
.Pp
The 0x0002 flag forces the
.Nm
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.
.Sh SEE ALSO
.Xr ata 4 ,
.Xr atapi 4 ,
.Xr intro 4 ,
.Xr pci 4 ,
.Xr pciide 4 ,
.Xr wd 4 ,
.Xr wdc 4
.Sh 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.
.Pp
The
.Nm
driver does NOT function correctly on
.Nx Ns /sparc64 .
