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
- ATI SB200
- ATI SB300
- ATI SB400, Parallel ATA
- ATI SB400, Serial ATA
- ATI SB700, Serial and Parallel ATA
Some SB700 controllers can hang under load when Native IDE mode is selected in
the system BIOS, but work fine in AHCI mode.
