If it's a Core Duo 2, then it's _probably_ 64bit EFI -- so try with the x86_64 Fedora 10 live image and I think it should at least be able to bring up grub. > > I never managed to get rEFIt to boot off of an MBR-based USB device. > > Some people said they did, but I have no clue what they did to do so > > :) > > I found the same kind of confusion too - some say it can be done others say > it can't.

If you can find a way to consistently get an MBR USB stick to boot, I'd love to help improve the docs there as I agree, it would certainly be the "best" thing. One thing you can do is make a boot cd that has just the isolinux bits and then points to a USB stick for the rootfs just by changing the root= and rootfstype= arguments in isolinux.cfg.
