+<p>(24 Jun 2005) The FreeBSD/sparc64 5.4-RELEASE should have stated that the
+FreeBSD/sparc64 GENERIC kernel prior to the upcoming 6.0-RELEASE officially only supports
+serial consoles. This is especially true for the FreeBSD/sparc64 5.4-RELEASE GENERIC
+kernel because the ofw_console(4) driver which also provides limited indirect support for
+graphical consoles has been replaced with the <a
+href="http://www.FreeBSD.org/cgi/man.cgi?query=uart&sektion=4&manpath=FreeBSD+5.3-stable">
+<span class="CITEREFENTRY"><span class="REFENTRYTITLE">uart</span>(4)</span></a> driver
+in favor better serial support.</p>
+
+<p>Due to this limitation to serial consoles the screen will stop working after the
+message ``<samp class="COMPUTEROUTPUT">jumping to kernel entry at...</samp>'' is
+displayed when trying to use the FreeBSD/sparc64 5.4-RELEASE GENERIC kernel with a
+graphical console, while FreeBSD itself continues working actually.</p>
+
+<p>If you want to use FreeBSD/sparc64 with a graphical console anyway you can do one of
+the following:</p>
+
+<ul>
+<li>
+<p>In case your machine is equipped with a Sun Creator, Sun Creator3D, or Sun Elite3D
+frame buffer card and a Sun RS232 keyboard you can install FreeBSD/sparc64 5.4-RELEASE
+with a serial console and afterwards compile a custom kernel with the following
+additional options:</p>
+
+<pre class="PROGRAMLISTING">
+device          sc
+device          creator
+options         KBD_INSTALL_CDEV
+</pre>
+
+<p>Additionally you have to enable the <tt class="FILENAME">tty[1-7]</tt> entries in <tt
+class="FILENAME">/etc/ttys</tt> like so:</p>
+
+<pre class="PROGRAMLISTING">
+ttyv0   "/usr/libexec/getty Pc"         cons25  on  secure
+# Virtual terminals
+ttyv1   "/usr/libexec/getty Pc"         cons25  on  secure
+ttyv2   "/usr/libexec/getty Pc"         cons25  on  secure
+ttyv3   "/usr/libexec/getty Pc"         cons25  on  secure
+ttyv4   "/usr/libexec/getty Pc"         cons25  on  secure
+ttyv5   "/usr/libexec/getty Pc"         cons25  on  secure
+ttyv6   "/usr/libexec/getty Pc"         cons25  on  secure
+ttyv7   "/usr/libexec/getty Pc"         cons25  on  secure
+</pre>
+
+<p>This will yield native support for these keyboards and frame buffers including VTY
+switching and X Window System. Note that this really requires at least FreeBSD/sparc64
+5.4-RELEASE otherwise it will not work on most of the UltraSPARC models.</p>
+</li>
+
+<li>
+<p>In case your machine is equipped with a ATI Mach64 frame buffer (found on-board in
+e.g. Sun Blade 100/150 and Sun Ultra 5/10 as well as on Sun PGX8 and Sun PGX64 add-on
+cards) or a PS/2 or a USB keyboard update to a FreeBSD/sparc64 6.0 from June 10 2005 or
+later. If you use the stock GENERIC kernel and <tt class="FILENAME">/etc/ttys</tt> from
+there no further action is required.</p>
+
+<p>This will yield native support for these keyboards and frame buffers including VTY
+switching and X Window System.</p>
+</li>
+
+<li>
+<p>In case your machine is equipped with hardware other than those mentioned above or you
+refuse to update to FreeBSD/sparc64 6.0 you can re-enable the ofw_console(4) driver as a
+last resort. To do so build a custom kernel with the following additional options:</p>
+
+<pre class="PROGRAMLISTING">
+device          ofw_console
+device          sab
+device          zs
+</pre>
+
+<p>and make sure to comment out the following kernel option:</p>
+
+<pre class="PROGRAMLISTING">
+device          uart
+</pre>
+
+<p>This will yield limited indirect support for any graphical console hardware, however
+with poor performance, and VTY switching as well as X Window System do not work with
+this. Note that ofw_console(4) is not really MPSAFE and therefore can result in panics
+under certain conditions.</p>
+</li>
+</ul>
