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

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