I *thought* I understood that there were 2 versions of the new SpeedStar. One with the Sierra HiColor DAC, and the other with the Edsun CEG DAC. The HiColor gives you 32768 true colors; the Edsun gives you, like, 700,000+ "fake" colors. The HiColor is easier to program for; the Edsun does edge smoothing using some tricky embedded image codes. So, which is it that you have? In any event, you won't be able to magically use those new modes without some fancy new software, I would guess. Assuming you got the HiColor version, did it come with a 15plane Windows 3.0 driver? Also, I didn't think that either chip provided their special features at resolutions beyond standard 640x480 VGA (maybe even less?). So, 800x600 by 32k colors is not possible (someone correct me...) ? Did it come with any demo software or pictures you can report on? -scott
