Hi all,
   OK, thanks to everyone for your responses. It's 5AM and I'm going
to try and answer as much as I can to get more info. Things are very
hosed up with this machine after whatever instructions I gave grub
didn't work. At the point where I'm supposed to get a grub splash
screen I get a blinking cursor, then it flashes for less than a second
some of the rootnoverify part from grub.conf so it's finding
something, and then I get a message about windows not starting because
<Windows root>\system32\hal.dll is missing.

   I have not yet this morning booted again from the install CD and
chrooted into the new 64-bit install. As I said, it's 5AM.

   OK, specific to this response there's nothing on the Safe_Cflags
page about this specific processor. (i5-661) I'll continue to study
that and take a very conservative path.

   Today all I want is to boot Gentoo with nothing but @system. I'm
happy to build that 10 times over with new CFLAGS if necessary before
going on to ANYTHING in @world. I don't NEED Gentoo just yet - I want
it but don't need it. What I need is to get grub working and be able
to boot into Windows first so I'm going to focus on that.

Thanks,
Mark
