<p class="Pp">The <code class="Nm">stpcide</code> driver supports the
    STMicroelectronics STPC x86 SoC internal IDE controllers, and provides the
    interface with the hardware for the <a class="Xr">ata(4)</a> driver. The
    driver features DMA mode 2 and PIO mode 4 transfer speeds.</p>
<p class="Pp">The 0x0002 flag forces the <code class="Nm">stpcide</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 IDE
    controller is wired up to the system incorrectly.</p>

<p class="Pp">The timings used for the DMA and PIO modes are for STPC Atlas and
    its siblings with their PCI clock configured at 33 MHz. Other speeds
    including the STPC Vega Ultra-IDE controller will need adjustments.</p>
