  <H2><A NAME="5"></A>5. Additional Notes</H2>
<p>Note that the Sierra SC1148{5,7,9} will not be distinguished from the
Sierra SC1148{2,3,4} by the probe. The only difference between the
two series as far as the server is concerned is that the {2,3,4} is
capable of 15bpp, while the {5,7,9} is capable of 16bpp. So if you
have a SC1148{5,7,9} and want to use 16bpp instead of 15bpp, you will
have to specify a <code>RAMDAC "sc11485"</code> line as shown above.</p>
<p>Some RAMDACs (like the Ti3025) require some mode timing consideration
for their hardware cursor to work correctly.  The Ti3025 requires that
the mode have a back porch of at least 80 pixel-clock cycles.  A
symptom of this not being correct is the HW cursor being chopped off
when positioned close to the right edge of the screen.</p>
