  <H2><A NAME="2"></A>2. XF86Config options</H2>
<p>Several options are supported in the "Device" section for the Mach32 X
server.  Most of them should be auto-detected if needed, but a few may
need to be deliberately set.  For example, the "Clocks" entry should
almost certainly be set after first running the server with the
<code>-probeonly</code> option, so as to avoid the probe in later runs.</p>
<p>
<dl>
<dt><b>Option "composite"</b><dd><p>This option will set the composite sync for
monitors that require this.</p>
<dt><b>Option "dac_8_bit"</b><dd><p>This option enables 8 bits per RGB value.  Note
this option does not work with all RAMDACs, and
is not considered supported by the Mach32 itself.</p>
<dt><b>Option "ast_mach32"</b><dd><p>This option sets some special handling for the AST
version of the Mach32 card that comes soldered in to
some of their motherboards.  This card will lock up
without this option.</p>
<dt><b>Option "intel_gx"</b><dd><p>This option sets the memory aperture address to
the hardwired value for the Intel GX Pro.  It is
equivalent to setting Membase to 0x78000000.</p>
<dt><b>Option "no_linear"</b><dd><p>This option disables the use of the linear mapped
framebuffer.  This should be auto-detected.</p>
<dt><b>Option "sw_cursor"</b><dd><p>This option allows you to use the software cursor
instead of the hardware cursor.</p>
<dt><b>MemBase baseaddress</b><dd><p>This entry specifies the video memory aperture
address.  Normally the aperture address is
automatically determined, but on some VESA Local
Bus systems the address chosen will not work.  If
the Mach32 X server is dying with a seg. fault,
then try setting the aperture address to another
location.</p>
<dt><b>Clocks <i>clock</i> ...</b><dd><p>This entry gives the clock rates for the server to use.</p>
<dt><b>Ramdac "<i>type</i>"</b><dd><p>This entry specifies the RAMDAC type.  The following
values are valid for <i>type</i>:
<ul>
<li>ati68830</li>
<li>sc11483</li>
<li>sc11486</li>
