Greetings, I brought this same error to the list back in May 2009. Under: failed to set mtrr: invalid argument. Well, I'm back using the same card: GeForce4 MX 440-SE - VideoRam 65536 - BusID PCI:1:3:0. The driver is different, I'm using: nvidia-driver-96.43.13 out of ports on a custom 8-STABLE kernel. Xorg starts up, and produces a desktop. But it's "dog slow", and the nvidia driver emits the following error: NVIDIA: failed to set MTRR 0xf0000000, 0M (write-combining) several times. I understand John Baldwin provided some "invaluable" help some time ago: http://lists.freebsd.org/pipermail/freebsd-hackers/2006-June/016995.html and I was wondering if anyone has gained any further "insight" with these cards, and how to better "interface" them in BSD. Last I spoke on the topic, I was informed that the memory was basically "untouchable" - or perhaps in other words; can't be manipulated. Has this changed? Surely someone else has had to deal with this besides me. It seems crazy to spend a "boat load" of $$ on these high performers, and not be able to use them on a high performing OS - no? :) Sure, the one I'm working with now is "legacy". But I have 3 near new, top of their line cards, and thus far it appears that if I ever hope to use them, I'll be forced to... hack, choke.. spin up a WIN CD. :( Thank you for all your time, consideration, and insight. --Chris H
