In this case it was the chipset drivers not being built in. 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!
