  <H2><A NAME="5"></A>5. Clock selection problems with some ET4000 boards </H2>
<p>XFree86 has some problems getting the clock selection right with some
ET4000 boards when the server is started from a high-resolution text mode.
The clock selection is always correct when the server is started from a
standard 80x25 text mode.</p>
<p>This problem is indicated when the reported clocks are different when the
server is started from the high-resolution text mode from what they are
when it is started from the 80x25 text mode.  To allow the server to work
correctly from the high-resolution text mode, there are some Option flags
that may be set in <code>XF86Config</code>.
To find out which flags to set, start the
server with the -probeonly flag from an 80x25 text mode and look at the
information printed by the server.  If the line:
<pre>
  VGAXXX: ET4000: Initial hibit state: low
</pre>

is printed, put the following in the SVGA, VGA16 and VGA2 sections of your
<code>XF86Config</code>:
<pre>
  Option "hibit_low"
</pre>

If the line:
<pre>
  VGAXXX: ET4000: Initial hibit state: high
</pre>

is printed, put the following in the SVGA, VGA16 and VGA2 sections of your
<code>XF86Config</code>:
<pre>
  Option "hibit_high"
</pre>
</p>
