>Once again, thank you. May I ask which cards you would recommend? I am >looking to kick this thing into TrueColor RGB mode. Sorry, I don't have any recommendation. In the VESA specification, video cards are not required to support any particular video modes. It is entirely up to the vendor to decide which video modes to support. We have to find out which mode is supported on which card. I don't have the list of supported video modes in each and every modern VGA card. (If there exists such a list, I would be most interested, though.) The current situation is "If the VESA BIOS Extension of your card does not support the video mode you want, bad luck." Oh, well... I personally use Millennium, which supports VBE 2.0, to test the vesa module. But, it doesn't mean that I find that this card is in any way better than the others regarding the VESA BIOS support. It is that this card just happens to be in my box... I used to have a no-name, S3-968 based card with VBE 1.2, and it worked well too. >Even normal VGA stuff >tends to flake out, as the new cards don't seem to support VGA fully now >that they support VESA. I don't know if the VBE support is the reason why a vendor no longer bothers to provide full support for all standard VGA modes. If the vendor is only interested in W*ndows market, I suspect they may decide to drop support for VBE as well as the standard VGA support, entirely or partially, and provide a W*ndows driver only.
