My experience is with the nForce3-Pro150 and the reference bioses for it. The nForce3-Pro250 might be better. The same goes for the nForce4. There were two problems on the Pro150 boards, possibly one was an artifact of the other. 1) the bioses were really shoddy. If I understand things correctly, this is because the reference bioses were shoddy and few motherboard makers bothered to do anything about it. 2) the APIC subsystem was very unreliable under FreeBSD. It is distinctly possible that this was bugs/races in our code, but I believe it far more likely that it was genuine chipset bugs or malfunctions due to bad bios setup of the hardware. The problems should exist on FreeBSD/i386 as well. I verified that the easiest ones to reproduce on my boards do show up in 32 bit mode as well. I was so gun-shy over the whole thing that I've avoided them like the plague. Since I was buying them myself and not using sample boards or the like, I didn't want to risk wasting money on more junk. For all I know, they've fixed bugs in the chipset. But I'm not going to be the one to fork out $ to find out, I've already lost enough sleep over them. -- Peter Wemm - peter@wemm.org; peter@FreeBSD.org; peter@yahoo-inc.com "All of this is for nothing if we don't go to the stars" - JMS/B5
