NAME
pdcide —
Promise IDE disk controllers
driver
SYNOPSIS
pdcide* at pci? dev ? function ? flags
0x0000
DESCRIPTION
Thepdcide 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.

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.
