Hello!


Since I switched to OS/2 2.0 GA, dviscr from the emTeX package doesn't
work any more.

The problem seems to be the return value of VioGetConfig. The little
Program below returns adapter=8 and display=13 on my machine (running
full screen). These values are not documented, at least not in any
documentation I have available.

My hardware: ALR PowerVEISA 486/25, Video7 VRAM VGA etc.

Does anybody have any documentation about these values of adapter and
display? Or any other values I don't know yet? My docs mention adapter
values 0,1,2,3,7 and display values 0,1,2,3,4,9.

Please post or mail if the test program below returns any different
values on your machine!

      0);                                   /* video handle       */

  printf("VioGetConfig returned adapter=%d, display=%d.\n",
         vioinConfig.adapter, vioinConfig.display);
}
