I know it can be done, how can I find info on vesa modes, or XGA and whatnot? Grapics hardware programming in General?

wikipedia, here...

alt.os.development im sure has similar topics... google may help.

i doubt there are any tutorials if thats what your looking for though, and the spec's can be difficult to read

Have you tried Google? Have you looked in the OSDev Wiki? Have you tried anything at all before asking?

I used google so it's not a dumb question.

Posting crap like that, is NOT going to get you any respect here...

In fact, I think it's safe to say your departure will be a joyous occasion..

did you really use google, os hacker64?

That's not even close to an excuse.

I'm looking for how to do it in protected mode. I get how to use the BIOS functions, but what good is that when they are not there?

protected mode and unknown mode(assuming real mode - your 1st post) are totally different enviroments.
VBE functions are optionally accessible via "Protected mode entry point". Such a point may not be implemented at all or only implemented for some function. I myself never used it was never interested in it but you can give it a try.
Other than that say thank you to intel & amd/ati for recent docs.

You can do several bios calls in protected mode using v8086. Most notably those include the video bios. Again, if you have read the other video-related threads that are currently active, and if you have searched the wiki, you would have known that already.

as jal said, that's not an excuse.

You can do all the mode set etc in realmode on booting, than if you have LFB (most do these days), you can you can use vesa as easy as using mode 13h in the old dos days, from pmode.

I think he already knew about the problem we have with video programming. I know that too, but I'm still hoping that someone on this forum has written some kind of nvidia driver, like they use in Linux, or that they managed to use the Linux module...

And please, I'm expecting a to-the-point answer on this! I'm not ready to give up on this ****-**** of a forum just yet.
By "to-the point" I mean this: If YOU haven't written an NVIDIA driver, or YOU haven't used the Linux module in your OS, shut the F up! If you HAVE, or you know someone who HAS written an NVIDIA driver or used the Linux kernel module successfully, please tell me. A link to some kind of tutorial would be good too.
That second part goes for any other Linux module...
I DON'T CARE ABOUT WHAT YOU HAVEN'T DONE!

It seems like the only way to get some answers around here is to repeat myself, like os.hacker64 did.
