NAME
artsata -- Intel i31244 Serial ATA disk controller driver SYNOPSIS
artsata* at pci? dev ? function ? flags 0x0000 options PCIIDE_I31244_DISABLEDMA DESCRIPTION
The artsata driver supports the Intel i31244 Serial ATA and controllers, and provides the interface with the hardware for the ata(4) driver. The 0x0002 flag forces the artsata driver to disable DMA on chipsets for which DMA would normally be enabled. This can be used as a debug- ging aid, or to work around problems where the SATA 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
Early samples of the Intel i31244 Serial ATA controller revision 0 had a bug affecting DMA data transfers. Full production samples have been fixed, but have the same revision number. The PCIIDE_I31244_DISABLEDMA option can be used to disable DMA on the buggy revisions. BSD

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, Fast- trak133 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. BSD
