I'm preparing to download the ISO images for Fedora Core 3 which I will then burn to CDs. I'd like to install the OS on a Pentium 4 and on an older Pentium 3. I'm assuming I want the x-86-compatible (32-bit) version for both machines -- is this correct? What sorts of machines use the 64-bit version? Thanks for the help with what is probably a dumb question.... Jerry
