<p class="Pp">The <code class="Nm">artsata</code> driver supports the Intel
    i31244 Serial ATA and controllers, and provides the interface with the
    hardware for the <a class="Xr">ata(4)</a> driver.</p>
<p class="Pp">The 0x0002 flag forces the <code class="Nm">artsata</code> 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.</p>

<p class="Pp">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
    <code class="Dv">PCIIDE_I31244_DISABLEDMA</code> option can be used to
    disable DMA on the buggy revisions.</p>
