Thanks for taking the time to try to help with this problem.
I am not sure since I have not researched it, but was told that the version 1.x of the Abit boards had a different revision of the nforce2 chipset. It seems that they all run fine. Been told that anyway.
I just tried the 2.4.22-rc2 patch and whatever was in there fixed my stability problems, but the system runs slower than molasses in January, and now X refuses to load with the nvidia driver. The 2D nv driver seems OK though. The XFree86.log shows that it is hanging when it tries to load glx. I think I might try the 2.6.X test kernel today. Just downloaded all the patches I need to make it work.
