I have seen some questions about installing a 2.4 kernel on fedora core 2 ( fc2 ) when searching on google on that topic. But I didn't find any detailed instructions about it. Anyway, here's a sketch of how I did it. Warning!: I haven't verified the correctness of these instructions. It seems that you need to install gcc32 to build a 2.4 kernel. That piece of advice I read here: http://www.redhat.com/archives/fedora-devel-list/2004-April/msg00702.html wget http://www.ftp.funet.fi/pub/mirrors/fedora.redhat.com/pub/fedora/linux/core/1/SRPMS/gcc32-3.2.3-6.src.rpm rpmbuild --rebuild gcc32-3.2.3-6.src.rpm rpm -Uvh /usr/src/redhat/RPMS/i386/gcc32-3.2.3-6.i386.rpm rpm -Uvh /usr/src/redhat/RPMS/i386/gcc32-debuginfo-3.2.3-6.i386.rpm ( You probably don't need the policy rpm package if you're skipping the 2.6 kernel. I removed it. But if I would do this installation procedure once more, I would try to keep it. The reason I removed it was because of a rpm dependency problem. I don't remember the details. It may be needed for booting up in 2.6 kernel ( I haven't verified that ). So this step might render your machine unbootable. Just do it if you can handle a rescue cd. Tell me if you managed to skip this step. ) rpm -e policy wget http://www.ftp.funet.fi/pub/mirrors/fedora.redhat.com/pub/fedora/linux/core/updates/1/i386/SRPMS/kernel-2.4.22-1.2188.nptl.src.rpm Find out what architecture you're having right now: rpm -q --qf "%{arch}\n" kernel Use that for --target rpmbuild --rebuild --target i686 kernel-2.4.22-1.2188.nptl.src.rpm rpm -i --oldpackage /usr/src/redhat/RPMS/i686/kernel-2.4.22-1.2188.nptl.i686.rpm rpm -i --oldpackage /usr/src/redhat/RPMS/i386/kernel-source-2.4.22-1.2188.nptl.i386.rpm ( I don't remember if I rebooted inte the 2.4 kernel at this point or not ) You have to rebuild the kernel-module-alsa package. I'm not sure about alsa-driver, alsa-lib, alsa-driver-debuginfo, alsa-utils. But it won't hurt if you rebuild them too. wget http://ftp.freshrpms.net/pub/freshrpms/fedora/linux/1/alsa-driver/alsa-driver-1.0.4-1.src.rpm wget http://ftp.freshrpms.net/pub/freshrpms/fedora/linux/1/alsa-lib/alsa-lib-1.0.4-1.1.fc1.fr.src.rpm rpmbuild --rebuild --target i686 --define 'kernel 2.4.22-1.2188.nptl' alsa-driver-1.0.4-1.src.rpm rpm -Uvh /usr/src/redhat/RPMS/i686/kernel-module-alsa-1.0.4-1_2.4.22_1.2188.nptl.i686.rpm rpm -Uvh --replacefiles /usr/src/redhat/RPMS/i686/alsa-driver-1.0.4-1.i686.rpm rpm -Uvh /usr/src/redhat/RPMS/i686/alsa-driver-debuginfo-1.0.4-1.i686.rpm rpmbuild --rebuild alsa-lib-1.0.4-1.1.fc1.fr.src.rpm rpm -Uvh /usr/src/redhat/RPMS/i386/alsa-lib-* wget http://ftp.freshrpms.net/pub/freshrpms/fedora/linux/1/alsa-utils/alsa-utils-1.0.4-1.1.fc1.fr.src.rpm rpmbuild --rebuild alsa-utils-1.0.4-1.1.fc1.fr.src.rpm rpm -Uvh /usr/src/redhat/RPMS/i386/alsa-utils-* The /etc/modules.conf is named /etc/modprobe.conf for the 2.6 kernel. If you're lucky just do cp /etc/modprobe.conf /etc/modules.conf You probably, though, have to edit that /etc/modules.conf to fit your needs. Maybe it's a better way to find a /etc/modules.conf from an older redhat installation to have as starting point for your editing instead copying from /etc/modprobe.conf. Boot up into the 2.4 kernel and if everything works nice, edit /boot/grub/grub.conf and change default=1 to default=0 I wrote these instructions rather quickly as a sketch. If I missed something please tell me. cheers, Erik Sjölund
