(SOLVED) Unable to run Live 64 bit on an AMD 64 4000+ machi

[mjt]

Downloaded the 64bit Live ISO, burned to DVD, ran md5sum
on ISO and the resulting DVD (both fine) ... booted up and
get the error message:

"kernel requires an x86_64 cpu, but only detected an i686 cpu
unable to boot - please use a kernel appropriate for your cpu"

Hi,

That's truly weird. It could be a Live CD bug or something wrong with your BIOS settings. I've installed Gentoo x86_64 on my new AMD Phenom box using minimal CD couple of weeks ago. Try to boot from Weekly Minimal Install CD.

I think it depends on the kernel version.
