<title>Supported Processors and Motherboards</title>
<para>Currently supported processors are the

and the <ulink url="http://www.intel.com/design/itanium2/index.htm">Itanium 2</ulink>.</para>

<para>Both Uniprocessor (UP) and Symmetric Multi-processor (SMP)
configurations are under active development. At this time,
SMP-enabled systems are considered less stable. The current
priorities are UP fixes to improve stability.</para>

<title>Supported Devices Overview</title>
<para>This section contains additional information about what
devices may or may not be supported by &os;/&arch;.</para>
<para>Except for the PC chipset embedded &man.ata.4; controllers,
most should work out of the box. Eventually, all
&arch;-compatible ATA controllers are expected to be fully
supported. Refer to the following sections for various disk
controllers and their current status.</para>
<para>In general, <quote>PC standard</quote> serial ports
supported by the &man.sio.4; driver are expected to work on
Intel legacy machines, but not PA legacy machines. The reason
is that all devices on HP machines are memory-mapped and there
is <emphasis>no</emphasis> ISA device support other than the PCI
dictated VGA legacy.</para>
<para>In addition to &man.sio.4; devices, the following devices
fail on non-Intel legacy machines (but should work on boxes with
an Intel legacy) because their drivers make ISA-specific
assumptions that do not hold:</para>
