DESCRIPTION
Theartsata driver supports the Intel i31244 Serial ATA
and controllers, and provides the interface with the hardware for the
ata(4)
driver.
The 0x0002 flag forces the artsata 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 SATA
controller is wired up to the system incorrectly.

BUGS
Early samples of the Intel i31244 Serial ATA controller revision 0
had a bug affecting DMA data transfers. Full production samples have been
fixed, but have the same revision number. The
PCIIDE_I31244_DISABLEDMA option can be used to
disable DMA on the buggy revisions.
