  <H2><A NAME="1"></A>1. DEC 21030</H2>
<p>
<ul>
<li>The DEC 21030 is supported by XFree86 in this release of XFree86 3.3.
</li>
<li>Current Known Problems

<ol>
<li>Only one modeline is accepted, this will be the first viable one
that matches other criteria.
</li>
<li>Due to the above, Virtual Resolutions is not supported either.</li>
</ol>

</li>
<li>The following options may be specified for the 21030 driver:
<dl>
<dt><b>Option "dac_8_bit"</b><dd><p>Turn on 8Bit BT485 RamDac (Multia and 8-plane TGA only).</p>
<dt><b>Option "dac_6_bit"</b><dd><p>Turn on 6Bit BT485 RamDac (Multia and 8-plane TGA only).</p>
<dt><b>MemBase 0x???????</b><dd><p>If the server does not detect the base address of the 21030, then
Check /proc/pci for the 21030 and look for the "Prefetchable 32 bit
memory at 0x???????" and enter this as your MemBase setting.
In XFree86 v3.3.2, if you are using Linux &gt; v2.0.27 with the PCI
routines the server should detect the base address automatically.</p>

</dl>
</li>
<li>No acceleration features of the 21030 have been taken advantage of yet!</li>
</ul>
