PIIXIDE(4) Device Drivers Manual PIIXIDE(4) NAME piixide - Intel IDE/SATA disk controllers driver SYNOPSIS piixide* at pci? dev ? function ? flags 0x0000 DESCRIPTION The piixide driver supports the Intel PIIX, PIIX3, PIIX4, and 82801 (ICH/ICH0/ICH2/ICH3/ICH4/ICH5/ICH6/ICH7/ICH8/ICH9/ICH10) IDE/SATA controllers and provides the interface with the hardware for the ata(4) driver. The 0x0002 flag forces the piixide 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. NetBSD 10.99 July 30, 2010 NetBSD 10.99
