IXPIDE(4) Kernel Interfaces Manual IXPIDE(4)
ixpide -- PCI IDE disk controllers driver
ixpide* at pci? dev ? function ? flags 0x0000
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.
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
ata(4), atapi(4), intro(4), pci(4), pciide(4), wd(4), wdc(4)
Some SB700 controllers can hang under load when Native IDE mode is
selected in the system BIOS, but work fine in AHCI mode.
