I don't know why you want the non-PAE version, but you could install the PAE version to start with and then install the non-PAE version after you boot the installed system. You can then boot into that kernel and remove the original PAE one.

I think the only way to start with the non-PAE version would be to use a kickstart file for installation. You might be able to force it that way.

Welcome to ask.fedora. Generally, you only need a non-PAE kernel if your CPU can't handle 64 bit instructions. And, unless you're using a very old computer, your CPU can handle the 64 bit instruction set, so you might as well use a 64 bit version of Fedora. Is there a particular reason that you're looking for this, or are you just curious?

@sideburns, PAE has nothing to do with 64-bit. It's only used for 32-bit in order to access RAM over 4GB.

Actually, it uses 64-bit instructions to reach past the 4 GB limit so that you don't have to convert to a 64-bit system. I know, because I changed from a 32-bit kernel to a PAE kernel when I moved to a mobo with 8 GB RAM. Then, when I had to reinstall, I went to 64-bit.

I looked it up to make sure I was remembering it correctly. PAE was originally made so that 32-bit CPUs could access more than 4GB of RAM. 64-bit CPUs of course still support it for 32-bit mode.
