KT400, AGP Support, and 1.0-4496
After a hiatus from using the NVIDIA drivers due to a serious hardware problem (http://forum.abit-usa.com/showthread...threadid=19135), I'm back in the saddle again. However, now I find with the 1.0-4496 drivers, I cannot enable AGP support.
$ more /proc/driver/nvidia/agp/status Status: Disabled I tried messing with the nvidia module options, but cannot seem to make them have any effect (WTF?! I thought this used to work?). What's the deal? Does anyone have AGP support working with a KT400 chipset? --- Redhat 9 w/ kernel 2.4.20-20.9 MSI KT4 Ultra (VIA KT400) Abit Siluro GF4 Ti4200 8x 128M |

AGP works fine on my KT400 chipset.

Are you using any special module options or NvAGP settings?
Last I knew, I was supposed to disable SBA in order to make it work, but the new drivers don't seem to honor that setting. (http://www.nvnews.net/vbulletin/show...threadid=10349) I really need AGP support for WineX3, otherwise none of my DirectX games work (because they can't allocate memory without it). |

I didnot have to do anything, just downloaded the Nvidia drivers off suse update and configured SaX2 for my graphics card.

Ok. Well, thanks anyhow.
In contrast to your apparent ease of use with the NVidia driver, when I install it fresh without alteration, I get ASCII garbage upon X startup and results in a hard lockup. I know there are others out there who at least used to have this problem. I think it might have something to do with the Ti4200 chipset. Perhaps this chipset does not support SBA? Anyone have the solution to this? Thanks! |

I had the same problem. AGPGART was disabled in the kernel. My Pro266T chipset PCI ID was not present in the pci_ids file and was not being used in the drivers/char/agp/agpgart_be.c. So no kernel AGP support. So I patched two files to add support. I got the PCI ID from /sbin/lspci -n
