(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
+uart(4) driver
+in favor better serial support.
+
+Due to this limitation to serial consoles the screen will stop working after the
+message ``jumping to kernel entry at...'' is
+displayed when trying to use the FreeBSD/sparc64 5.4-RELEASE GENERIC kernel with a
+graphical console, while FreeBSD itself continues working actually.
+
+If you want to use FreeBSD/sparc64 with a graphical console anyway you can do one of
+the following:
+
+
+-
+
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:
+
+
+device sc
+device creator
+options KBD_INSTALL_CDEV
+
+
+Additionally you have to enable the tty[1-7] entries in /etc/ttys like so:
+
+
+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
+
+
+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.
+
+

+
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 /etc/ttys from
+there no further action is required.
+
+This will yield native support for these keyboards and frame buffers including VTY
+switching and X Window System.
+
+
+-
+
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:
+
+
+device ofw_console
+device sab
+device zs
+
+
+and make sure to comment out the following kernel option:
+
+
+device uart
+
+
+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.
