True, but by design, multi-core CPUs behave exactly like normal SMP machines. (with "more" sockets) RHEL5 may be unable to access new core extensions (E.g. new SSEn/3DNow, Better Cool & Quiet, VT/SVN extensions, etc) or may not be able to detect the CPU family/version under /proc/cpuinfo, but it should boot just fine and detect all the cores. *, **. - Gilboa * As long as number of the cores then does not exceed the complied-in NR_CPUS value inside the kernel. ** Wrongly detecting the number of cores - per socket, might exceed the license - though I assume that RedHat will release a kernel fix once such problem is detected. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
