PCIIDE(4) Kernel Interfaces Manual PCIIDE(4)

NAME

pciidePCI IDE disk controllers driver

SYNOPSIS

pciide* at pci? dev ? function ? flags 0x0000
pciide* at pnpbios? index ?

DESCRIPTION

The pciide driver supports the PCI IDE controllers as specified in the "PCI IDE controller specification, revision 1.0" draft, and provides the interface with the hardware for the ata driver. Please use the chip-specific drivers for the following controllers for enhanced and DMA support:

The 0x0001 flag forces the pciide driver to use DMA when there is no explicit DMA mode setting support for the controller but DMA is present. If the BIOS didn't set up the controller properly, this can cause a machine hang.

The 0x0002 flag forces the pciide 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.
