TK> What should i do to run 3000 chipset software on a Tsengabs 4000 SVGA adapter? TK> Toine Kuiper, tgtbtk@chem.tue.nl I'm definately no expert on this, but it seems to me that often when I run TS 3000 software on my ET4000's (BOCA & STB), there are often large gaps in the screen horizontally. This only happens in the extended modes, and I have yet to see a ET4000 program do this. Perhaps I should describle the effect a little more and see if anyone else has seen this... Imagine a .GIF file properly loaded onto the screen (proper colors, aspect, resolution, etc.) BUT there are big, black, horizontal stripes across the screen. They are about 1.5 inches or so in height, and are the same size as the stripes of "proper" picture. Altogether, the 4 or so stripes occupy exactly half of the screen. A really crude and naive (but explanatory) description might be that it looks like every other RAM chip is missing. :-) Has anyone else seen this? More importantly, is there a fix? Note that I have never seen the 320x200 or any other normal VGA mode do this, only the Extended modes. Any ideas, pointers?
