nForce2 chipset and agpgart: unsupported bridge?

nForce2 chipset and agpgart: unsupported bridge?

Post by Randy S » Wed, 25 Dec 2002 23:30:08



Hi folks,

  I recently acquired a motherboard with an NVidia nForce 2 chipset (more
specifically, its a Chaintech CT-7NJS). I have a Radeon 9700PRO video card
that I'm running in this machine.  I've got integrated networking, sound,
XFree86, etc. working, but am having trouble getting 3D acceleration to
work.

   My kernel is 2.4.19.  Agpgart does not appear to be able to detect the
nForce 2 chipset's bridge. There is no vendor entry for nvidia at all,
actually -- otherwise I might have gotten by with agp_try_unsupported=1.

   Has anyone written nForce2 support for agp? Is so, where can I find the
source?   I found drivers for the nvidia IGP (which I don't have), but not
for agpgart itself at the nvidia site.  If I find the source, I believe I'll
have to merge it manually since the 3D driver for Radeon 9700 (fglrx)
includes a modified agpgart_be.c.

    If this is not a new question, my apologies -- I couldn't find an answer
anywhere in the archives.

   Please CC me directly on any reply, as I'm not currently subscribed.

Thanks!
   Randy Sharo

nForce2 chipset and agpgart: unsupported bridge?

The way I know it you must first of all build the nvagp modules
downloadable from nVidia's web site and use those instead of agpgart.
However, the snafu is that you must have an nVidia video card to go
along with it (or use the on-chipset *video card.) So you're SOL i
think, at least until nvidia gets a bit less selfish.

Like the topic says = )

I was just wondering if its been planned to make nForce2 chipsets
