genlock board 3.2.

[Reinhard Doelz]

There are supposedly some changes in calling the genlock board. The routines
I used previously to get a plain PAL on the video output do not work any 
longer. Is there someone in netland who has a routine which swtiches to 
PAL (or NTSC) and back to the graphic 60 Hz? Any experience how to prepare
the output in a way that is better than garbage (called preview quality by 
SGI).
