how to installiere Xsvga-support in AmigaUNIX
=============================================

1) install AmigaUNIX 2.1c (with patch-disk)
2) boot the system and log in as "root"
3) after gunzipping install.svga.gz, apply "sh install.svga" and
   follow the instructions
5) at the moment the following boards are supported
    - Domino 32K
    - Domino 16M
    - oMniBus
    - Merlin (in ZorroII mode)
    - Picasso II (only in linear mode)
    - Piccolo (in ZorroII mode)
    - Spectrum (in ZorroII mode)
   The last four boards have blitter support, all boards support panning
   of virtual/oversized screens.
   The limitation to ZorroII mode is because the AMIX memeory mapping
   system can't deal with ZorroIII boards and the source for the important
   parts is not prvided with AMIX... :-(
   I left out segmented boards (PicassoII in segemnted mode, Retina Z2)
   because of workload and performance reasons...

6) the install.R* scripts ask for a floppy distribution or a tape...
   To create the floppy distributions, gunzip the X11R4.tar.gz file and
   archive it to floppies with "bru".
   For re-creating the tape distribution gunzip X11R4.tar.gz and
   X11R5_bin.tar.gz and dd them to a tape, first the R4 and after that
   the R5 onto the same tape
   The R4 distribution is only the R5 server and neccessary files to
   make the R5 server work in the default R4 environment, AMIX provides.
   The R5 distribution is the whole binary X11R5 environment.

7) the mode-definitions in dthe file "XsvgaConfig" are in the same
   format as for the common XFree86 server used in PC-Linux.
   PicassoII users have an advantage, they can convert the PicassoII
   screenmodes into the X-format with the "Listmodes" program, the
   ouput needs just paste-ing into XsvgaConfig.
   Users of other boards maight need some fiddling and trying.

8) the format looks like this:
     - name of modes (as in Screenmode)
     - pixelclock in MHz
     - number of visible pixels
     - position of horizontal sync-start
     - position of horizontal sync-stop
     - total length of scanline. (Sichtbare Pixel und Rucklauf),
       pixelclock divided by this gives line-frequency
     - number of visible scanlines
     - position of vertical sync-start
     - position of vertictal sync-stop
     - total scanlines in frame
       linefrequency divided by this gives frame rate
     - flags mit
        H+ horizontal sync positive (default: negative)
        V+ vertical sync positive (default: negative)
        I  interlace mode
        D  doublescan mode (interlace und doublescan NOT simultaneously)
        E  video-encoder (only on PicassoII)

    Attention: There are NO sanuty checks performed. You can destroy you
               monitor by feeding to high frequencies into it. I am not
               to be held liable for any damage or harm you might cause!
