Im running 6.0 and I have som problems with the nvidia-drivers and AGP support. Its a SiS 661 chipset. It seems to be found: agp0: <SiS 661 host to AGP bridge> mem 0xe8000000-0xebffffff at device 0.0 on pci0 And this it was sysctl says: dev.agp.0.%desc: SiS 661 host to AGP bridge dev.agp.0.%driver: agp dev.agp.0.%location: slot=0 function=0 dev.agp.0.%pnpinfo: vendor=0x1039 device=0x0661 subvendor=0x1043 subdevice=0x8113 class=0x060000 dev.agp.0.%parent: pci0 And a /dev/agpgart exists. The real problem appears when I try starting X with the nvidia-drivers. The SiS 661 chipset is not supported by the nvidia AGP driver (it was the same under Linux, so I used the AGPGART module there), so I should used the native FreeBSD AGP support. I have the right NvAGP option in xorg.conf and everything, but my machine reboots when X is started. No error message is logged anywhere. The driver seems to work fine with my gfx-card, a GeForce4 MX 4000, because X runs fine with AGP disabled, but with half the performance (glxgears) than I had under Linux. The problem is apparently that the nvidia-driver cant use the FreeBSD AGP driver. I've tried with 7676, 7667 and 7174 (compiled the latest with GPU_LEGACY_SUPPORT) and it is the same problem. Is there someway to at least get an error message before the reboot or something? -- regards, Jeppe W. Larsen "Logic is the beginning of wisdom; not the end."
