    <title>Overview</title>

    <para>This document tries to provide a starting point for those
      who want to run &os; on an &arch.print;-based machine. It is
      aimed at providing background information on the various
      hardware designs. It is not a replacement for the systems
      manuals.</para>

    <para>The information is structured as follows:
      <itemizedlist>
        <listitem>
	  <para>General hardware requirements to run &os; on &arch;.</para>

          systems/boards supported by &os;.</para>

    <title>In general, what do you need to run &os; on a &arch;</title>

    <para>&os;/&arch; requires an &arch.print; system.  Currently, the
      newer PCI-based systems are supported better than the older SBus
      based systems.  The following systems are known to work to
      varying degrees:</para>

      </itemizedlist>

    <para>Ultra 80 and Blade 1000 are expected to work, maybe
      with minor modifications.  SMP is supported on Ultra 2 and 60
      workstations and Enterprise 220R, 250 and 420R servers.</para>

    <title>Supported Hardware Overview</title>

    <para>A word of caution: the installed base for &os;/&arch; is not
      nearly as large as for &os;/Intel. This means that the enormous
      variation of PCI/ISA expansion cards out there has much less
      chance of having been tested on &arch; than on Intel. This is
      not to imply they are doomed to fail, just that the chance of
      running into something never tested before is much higher.
      <filename>GENERIC</filename> contains things that are known to
      work on &arch; only.</para>

    <para>The PCI bus is fully supported.  SBus support is limited,
      but is reported to work well enough to netboot an SBus-based
      Ultra 2 workstation.</para>

    <para>1.44 Mbyte floppy drives are <emphasis>not</emphasis> yet
      supported.</para>

    <para>ATA and ATAPI (IDE) devices are supported via the &man.ata.4;
      driver framework. &perforce;</para>

    <para>There is full SCSI support via the CAM layer.  However, only
      NCR/Symbios cards are currently working.  Adaptec 2940x (AIC
      7xxx chip-based) and &man.isp.4; cards should be supported soon.
      Be aware that SCSI cards must contain Sun FCODE in order to use
      them as a boot device from OpenBoot.</para>

    <para>If you want to boot your sparc64 over the Ethernet you will
      obviously need an Ethernet card that the OpenBoot console
      recognizes.</para>

    <para><devicename>hme</devicename>, <devicename>gem</devicename>,
      and <devicename>eri</devicename> based network devices.</para>

    <para>The <quote>PC standard</quote> serial ports found on most
      newer Sun workstations are supported.</para>
