IXPIDE(4)               NetBSD Kernel Interfaces Manual              IXPIDE(4)

NAME
     ixpide -- PCI IDE disk controllers driver

SYNOPSIS
     ixpide* at pci? dev ? function ? flags 0x0000

DESCRIPTION
     The ixpide driver supports the ATI Technologies IXP IDE controller, and
     provides the interface with the hardware for the ata(4) driver.

     The 0x0002 flag forces the ixpide 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.

HARDWARE
     The supported IDE controllers are
     o   ATI SB200
     o   ATI SB300
     o   ATI SB400, Parallel ATA
     o   ATI SB400, Serial ATA
     o   ATI SB700, Serial and Parallel ATA

SEE ALSO
     ata(4), atapi(4), intro(4), pci(4), pciide(4), wd(4), wdc(4)

CAVEATS
     Some SB700 controllers can hang under load when Native IDE mode is
     selected in the system BIOS, but work fine in AHCI mode.
