<p class="Pp">The <code class="Nm">EBus</code> bus is designed to provide the
    ability to put ISA and traditional Intel-style peripherals in a SPARC based
    system with a minimal amount of glue logic. Typically, it is implemented in
    the PCIO IC from SME, which also implements a <a class="Xr">hme(4)</a>
    compatible PCI network device
    (&#x2018;<code class="Li">network</code>&#x2019;). The
    <code class="Nm">EBus</code> has four DMA channels, similar to the DMA seen
    in the <a class="Xr">esp(4)</a> SCSI DMA.</p>
