I am looking for nVidia NV17 geForce 4 MX 440 port programming info so that i can change video modes in pmode i was wandering if anyone knows where to get this infomation.

I read in a previous message about the protected mode interface on int 0x10, but
it only provides three functions and not the ones that i want.

and VGADOC doesnt support nvidia cards (is there a doc like this for nvidia)

Any help appriciated

Such doc is top secret information, so you would't be able to find it.

If you have got linux on your system,

do a search for NVIDIA_kernel-1.0-2960.src.rpm

once rebuilt the sources (on my system) are in

/usr/src/RPM/SOURCES/NVIDIA_kernel-1.0-2960

I haven't figured out much of them as yet

I am currently using the vbe3 extensions to set mode and get framebuffer,
and i am trying to work out how to use VBE/AF functions (mainly for the mouse cursor & the blt functions)

bye

I believe they're talking about the nVidia kernel driver.  As of 2.4 (?) the kernel contains DRI modules for graphics cards that XFree86 uses for its rendering... such is my understanding, anyway.

The XFree86 "drivers" are fairly thin, I believe... leaving most of the logic to the kernel modules.  But, of course, I can't tell for sure;  I haven't actually researched this... this was merely my understand at the time :)

Cheers,
Jeff

The official nVidia driver is not completely open source: Only the source code of the "kernel module" you mentioned is availible. AFAIK it's only "glue code" which allows nVidia to reuse their (closed source) windows drivers on linux. Kinda like the Captive project does. (correct me if I'm wrong)
The "nv" driver in the XFree86 source package should be more interesting, but I haven't had a closer look yet.
