    x86_64 is the 64bit installation for a x86 architecture. I guess this won't work in your case.
    i686 is for a x86 32bit architecture.

    more about this and (i368, i486...) can be found here: http://www.sandpile.org/

    If your CPU has x86_64 support then either i686 or x86_64 Linux will work. If your CPU lacks x86_64 support then only i686 will work.If both work, 512MB is low enough that the disadvantages of x86_64 for small amounts of ram might be enough of a factor to affect the decision . 40GB hard disk is also low enough to notice the extra disk space needs of x86_64 but not low enough to force the decision of i686.
