re: Fedora 10

I've tried to download and burn Fedora 10 and Fedora 11 only to find that the first disc will not install. I cahnged hds, and added memory, check ed the platform type. I burned both the i386 and the 64 bit editions to no avail. The processor is an intel 586 or MMX. The machine worked fine with Win 98 and still does. Any suggestions?
