# 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

- ATI SB200
- ATI SB300
- ATI SB400, Parallel ATA
- ATI SB400, Serial ATA
- 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.
