   <h3><font color="#0000e0"><strong>History:</strong></font></h3>
   
   <p>
   The OpenBSD/macppc port started as OpenBSD/powerpc, and was initially
   focused on Motorola computers with OpenFirmware, and VI Power4e boards.
   This port was eventually thrown away after OpenBSD 2.5 was released.
   As a result there was no OpenBSD/powerpc port for the 2.6 and 2.7 releases.
   In the meantime, a new port was started, focusing on Apple hardware, and
   based on code from NetBSD/macppc, and after a lot of work from Dale Rahn,
   OpenBSD 2.8 was released with a powerpc port.
   As work on the port continued, it was renamed to OpenBSD/macppc for 3.0.

   The X-Window system is supported on all MacPPC systems, however
   only the ATI graphics adapters are supported by an <i>accelerated</i>
   X server at the current time.
   The nVidia accelerated X server does not currently work, however nVidia
   (and ATI) cards can be used by X in framebuffer (unaccelerated) mode,
   at the boot resolution and color depth using the wsfb driver (installed by
   default).
   </p>
   
   <p>
   Directions on enabling the accelerated X server can be found
   in the <tt>/usr/X11R6/README</tt> file on the installed system.
