1.  Supported hardware

This server supports the following 3DLabs chipsets:

   o GLINT 500TX with IBM RGB526 RAMDAC

   o GLINT MX with IBM RGB526 and IBM RGB640 RAMDAC

   o Permedia with IBM RGB526 RAMDAC

   o Permedia 2 (classic, 2a, 2v)


2.  Features

   o accelerated

   o hardware cursor

   o DPMS support

   o supported color depths

        o GLINT MX/500TX: 8/16/32 bpp

        o Permedia: 8/16/32 bpp

        o Permedia 2: 8/16/24/32 bpp


3.  XF86Config Option

      Option "sw_cursor"
            disable the hardware cursor.

      Option "no_pixmap_cache"
            disables use of the pixmap cache. Might be useful if drawing errors
            occur.

      Option "no_accel"
            completely disables acceleration. Usually not recommended.

      Option "pci_retry"
            stall the PCI bus while the graphics engine is busy. While this

            might give slightly higher performance, you run the risk of dis-
            turbing other devices that are waiting to be serviced by the pro-
            cessor. This option may cause problems with SCSI cards, serial con-
            nections, sound cards, etc.

      Option "firegl_3000"
            needed for the Diamond Fire GL 3000 in order to use the primary
            output on that card. The second screen is currently not supported.

      Option "overclock_mem"
            Run the memory at a higher clock. Useful on some cards with display
            glitches at higher resolutions. But adds the risk to damage the
            hardware. Use with caution.


4.  Bugs and Limitations

   o The 500TX and MX chipsets cannot switch modes, therefore only the first
     mode on the modes line is available.

   o In some color depths without acceleration there are color problems.

   o While the server is accelerated, there is room for improvement. As our
     development is focusing on XFree86-4.0 we are not planning to change that
     in the 3.3.x branch. XFree86-4.0 will include a significantly faster
     server.

   o Special thanks to Elsa AG, Aachen for making it possible for us to develop
     this server and furnishing us with plenty of boards and information to
     help us on the way

   o Very special thanks to SuSE GmbH, Nuernberg for allowing some of us to
     work on this server on paid time, thereby financing development of this
     server.
