## 1. Supported chipsets

The "ark" driver in the SVGA server is for ARK Logic graphics chipsets. The following chipsets are supported:

ARK1000PV (ark1000pv)

  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).

ARK1000VL (ark1000vl)

  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.

ARK2000PV (ark2000pv)

  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.

ARK2000MT (ark2000mt)

  This is a newer chip, compatible with the AR2000PV.

The ARK2000MI is not yet supported.

The chipset may not be detected automatically. In this case use a line like `Chipset "ark1000pv"` in the `Device` section of the XF86Config file. Any options must also be specified in this section.
