The x86_64 kernel will be installed and used on compatible hardware, even when installing a 32-bit operating system. The PAE kernel will be used on 32-bit hardware, where appropriate" Note that https://fedoraproject.org/wiki/Features/ArchitectureSupport#Contingency_Plan says "For x86_64-on-32: do not ship x86_64 on 32-bit x86, only ship 32-bit kernels. This contingency plan has been enacted." I think the idea here was to use the 64-bit kernel if installing the OS on 64-bit hardware, even if the OS software would be 32-bit. While 32-bit programs wouldn't be able to address large chunks of RAM, at least the kernel would - so running multiple instances of 32-bit programs could make use of the whole RAM. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
