  <H2><A NAME="1"></A>1. Supported chipsets </H2>

<p>The "ark" driver in the SVGA server is for ARK Logic graphics chipsets.
The following chipsets are supported:
<dl>
<dt><b>ARK1000PV (ark1000pv)</b><dd><p>Chipset with 32-bit DRAM interface, supports fast DRAM timing,
for VESA and PCI bus. Has powerful "coprocessor" for graphics
acceleration.
The max supported resolution/refresh depends on the RAMDAC
used on the card; expect 256 colors up to 80 or 110 MHz dot clock;
16bpp is also supported, as is 24bpp (packed).</p>
<dt><b>ARK1000VL (ark1000vl)</b><dd><p>Older chip, VLB only. More or less compatible with ARK1000PV.
It has is not been tested. You may have to disable acceleration
and linear addressing.</p>
<dt><b>ARK2000PV (ark2000pv)</b><dd><p>64-bit version of the ARK1000PV. Note that an ARK2000PV equipped
with 1Mb of DRAM is about equivalent to the same card with an
ARK1000PV chip; 2Mb is required for 64-bit operation. Again
the RAMDAC used on the card determines the max supported dot
clocks. At 8bpp, multiplexing over a 16-bit RAMDAC path is not
yet supported so expect dot clocks up to 110 MHz; 16bpp and 32bpp
are supported, as well as experimental packed 24bpp, depending
on the RAMDAC.</p>
<dt><b>ARK2000MT (ark2000mt)</b><dd><p>This is a newer chip, compatible with the AR2000PV.</p>

</dl>
</p>
<p>The ARK2000MI is not yet supported.</p>
<p>The chipset may not be detected automatically. In this case use a line
like <code>Chipset "ark1000pv"</code> in the <code>Device</code> section of
the XF86Config file. Any options must also be specified in this section.</p>
