rdcide
RDC IDE disk controllers driver

rdcide* at pci? dev ? function ? flags 0x0000

The rdcide driver supports the RDC IDE controller as found in the vortex86 and PMX-1000 system on chip, and provides the interface with the hardware for the ata(4) driver.

The 0x0002 flag forces the rdcide 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.
