- I little understanding of what VESA will help you understand the "lack of
- support". VESA is a standard by which SUPERVGA has been defined for methods of
- accessing the extended resolutions. The VESA standard does not include
- graphics co-processors and accelerators.
-
- The ATI Graphics Ultra + is a Graphics Coprocessor card that incorporates VGA
- and SuperVGA. The card only support 16bit and 24bit color through the Graphics
- Coprocessor and not the SuperVGA section. So, no VESA driver for the product
- is available.
-
- Is there a VESA driver for 24 bit color? Could be. I haven't seen the most up
- to date VESA specs, so they may have been updated. The last one set I looked
- at did not include. It is definitely possible to accomplish it with a SuperVGA
- card, but with the coprocessor to assist the graphics, it would be SLOOOWWWW!.
-
- What DOS apps are you running that require 24 bit VESA support? For programs
- like 3D Studio and AutoShade, ATI provides a rendering driver with the card.
