I'm trying to figure out how to patch a FC source kernel. I've downloaded and installed the source rpms and now have a bunch of .config files .patch files a linux-2.6.11.tar.bz2 etc. The FC release notes say to do a rpmbuild -bp --target=<arch>kernel.spec (where <arch> is the desired architecture). I would assume this would be something like i386, i586, i686? (I know this is s silly question) how do I know what to set this to? This should create a kernel tree in /usr/src/redhat/BUILD/ , I then copy the correct .config file to this directotry (what's the -smp mean?) Do I apply patches to this resulting kernel tree like: patch -p1 -d s3_late_bios_new.patch ?? and then: make oldconfig make bzImage modules make modules_install install ?? I'm assuming that this process does not automatically update grub? Thanks, Jeff Birt Electronics Engineer Integrated Systems Facility University of Missouri - Rolla 573.341.6058
