  <H2><A NAME="4"></A>3. Configuration:</H2>
<p>The MGA driver should auto-detect all supported hardware so you needn't 
have anything other than the Identifier in the Section "Device" of the
XF86Config file.  When running the XF86Setup or xf86config programs one    
merely needs to select a Matrox card so that the correct server will be  
used.  One need not and should not specify a RAMDAC, clockchip or allow 
the setup program to probe for clocks. The driver will auto-detect the   
amount of video ram present, however, due to some hardware problems
this is not detected for the MGA2164W (Millennium II) or G100/G200.
In this case users should specify the amount of video ram in the Section
"Device" of the XF86Config file. eg:</p>
<p>
<pre>
        VideoRam 4096
            or
        VideoRam 8192
            or
        VideoRam 16384
</pre>
</p>
<p>as appropriate so that the server doesn't have to probe for it.</p>
<p>The following Section "Device" options are supported by the MGA driver:
<ul>
<li>Option "sw_cursor"
<p>Will disable the hardware cursor on the Millennium and Millennium II.</p>
</li>
<li>Option "no_accel"
<p>Will disable all hardware acceleration (oh my!).</p>
</li>
<li>Option "no_pixmap_cache" 
<p>Will disable caching of pixmaps in offscreen video memory.</p>
</li>
<li>Option "sync_on_green"
<p>Will enable syncing on green for sync-on-green monitors (these are typically
fixed frequency workstation monitors).</p>
</li>
<li>Option "pci_retry"
<p>This will allow the MGA hardware to generate a pci_disconnect based on 
accelerator FIFO status. This can yield large performance boosts for
some graphics operations but has a tendency to hog the PCI bus so 
it is turned off by default.</p>
</li>
<li>Option "mga_sdram"
<p>This will force the server to disable sgram features such as block
mode fills and hardware planemasks.</p>
</li>
</ul>
</p>
