Didnt shorty use a 64-bit version SuSE when he went to MSI?
Also Gentoo. I just emerged 2.6.1 from gentoo and it is very fast but 2.4.22 had support for k8's
Ok I have the AMD 64bit version of Redhats Fedora project and I get a kernal panic about 15 seconds into the initial boot from the CD.
Bummed. Will try to shake it out when I get a few more minutes free time. (yeah right)
All linux distros should work. Only some distros are designed for x86_64.
Try gentoo or ubuntu
And remember that 95% of the applications are not supported under x86_64 so you will have to use emulation. An example is lilo and grub. However I heard about some patches for those.
The 2.6 kernel supports x86-64, so I don't see what else needs to be changed. Just compile that (make sure you set it to Hammer on the CPU type menu), use it and then everything else should take suit.
They worked fine on the Fedora 64bit versions.
