I'm now booting successfully into Gentoo, albeit a very stripped down nothing-but-install-CD system. At least now, as far as Gentoo is concerned, I can work with tools on the hard drive and maybe see what I can make the machine do. hdparm says 65MB/Sec so I've got enough disk speed to make an emerge @world go reasonably fast. top shows all 4 processors. This is my first SMP machine running Gentoo. I'm looking forward to it. My graphic performance (not important to me as I do mostly audio stuff) will be low as I'm using the 900MHz Intel VGA that's built into the processor of the i5-661, not the chipset, so far less traffic to the North Bridge if I understand correctly. We'll see. I'll be back. Windows still doesn't boot and I don't so far think it's a grub problem but I need to do some research on the error messages... Thanks!
