<p class="Pp">The Amiga architecture uses a common machine independent scsi
    sub-system provided in the kernel source. The machine independent drivers
    that use this code access the hardware through a common interface. (see
    <a class="Xr">scsibus(4)</a>) This common interface interacts with a machine
    dependent interface, such as <code class="Nm">zssc</code>, which then
    handles the hardware specific issues.</p>
<p class="Pp">The <code class="Nm">zssc</code> interface handles things such as
    DMA and interrupts as well as actually sending commands, negotiating
    synchronous or asynchronous transfers and handling disconnect/reconnect of
    SCSI targets. The hardware that <code class="Nm">zssc</code> uses is based
    on the NCR53c710 SCSI chip.</p>
