I recently purchased a brand new TVGA 8900 that will do 800x600x256 and 1024x768x16. The reason I'm sending out this post is to see if anyone can give me hints as to how to get this card to work with certain programs. Example: While using PICEM 2.0, I am able to display any GIF, in all modes, including 800x600x256 and 1024x768x16. This program is very slow, though. If I use VPIC 3.0, I run into the following problem: If I try to display a picture in ANY 256 color mode (including 320x200!) the program maps the pixels wrong. It will paint the first 5th of the screen fine, then jump back to the top and paint the next 5th over the first 5th, then jump down to the proper place and paint the next fifth, then jump up to the top of that and paint over it, then finally jump down and paint the last fifth in the correct place. I have tried configuring the program for every chip set it knows, (including the proper one, Trident, which seems to work best, the others just paint ALL of it in the first fifth of the screen) and it does seem to be setting the mode correctly, just not doing the mapping right. It works fine in 16 color modes, though, EXCEPT 1024x768, which it seems to just scramble the picture. Also, I have a fractal generating program which does this exact same thing as VPIC. (except 1024x768 works) My questions are: a) Why does PICEM work and VPIC doesn't? PICEM didn't even require any configuration! b) What can I do to get VPIC and other programs like it to work in the future? Any possible help/suggestions/etc would be appreciated!

If VESA support is available for the card (look at the software that
came with the board), you can check out all the SuperVGA modes using
VUIMAGE Gif/Tiff Viewer 2.62 or 2.70. Use the VESA driver that comes
with the program. VUIMAGE 2.62 is available from SIMTEL (VUIMG262.ZIP).

Try changing your dip switch settings to sw 2 & 5 off. Part of the reason is the Trident chip (while good), isn't compatible with others (TSENG, Paradise, etc.) at the higher resolutions. (Henceforth drivers for application products). Larry Boyd (BOYD@ENR.prime.com)
