     artsata -- Intel i31244 Serial ATA disk controller driver

     artsata* at pci? dev ? function ? flags 0x0000
     options PCIIDE_I31244_DISABLEDMA

     The artsata 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.

     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.
