No AGP support for Quadro4 900 XGL on Dell 650?
We just bought a loaded Dell Precision 650 with a Quadro4 900 XGL. It is running kernel 2.4.20 (Debian).
Everything works (even stereo) except for AGP.
We see this:
1 kraken:/home/jsmith% dmesg | grep gart
Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 816M
agpgart: Unsupported Intel chipset (device id: 2550), you might want to try agp_try_unsupported=1.
agpgart: no supported devices found.
2 kraken:/home/jsmith% dmesg | grep AGP
0: NVRM: AGPGART: unable to retrieve symbol table
5 kraken:/home/jsmith% cat /proc/driver/nvidia/agp/status
We've gone through the usual dance of trying all the NvAgp options - we even tried the agp_try_unsupported=1 kernel commandline suggested by the agpgart error message - it doesn't help.
The motherboard in this machine has an Intel E7505 chipset. So are we out of luck? It's very bad news if so - we bought this machine specifically to be a Linux graphics workstation...please help!
