(I've tested it in my computer: fedora7. It will generate two rpm packages: 1. /usr/src/redhat/SRPMS/kernel-2.6.21prep-1.src.rpm; 2. /usr/src/redhat/RPMS/i386/kernel-2.6.21prep-1.i386.rpm)
step 1: download the kernel source
The default kernel source can be found through any Fedora mirror. Look in the directory "/source/SRPMS/" under the "/7/" directory .
For example: http://download.fedora.redhat.com/pub/fedora/linux/releases/7/Fedora/source/SRPMS/.
step 2: install the src.rpm
#rpm -ivh kernel-2.6.21-1.3194.fc7.src.rpm
step 3: install sparse
#yum install sparse
step 4:
#rpmbuild -bp --target=$(uname -m) /usr/src/redhat/SPECS/kernel-2.6.spec
step 5:
#make rpm
step 6:Install The New Kernel
#cd /usr/src/redhat/RPMS/i386/
#rpm -ivh kernel-2.6.21prep-1.i386.rpm
step 6:
#mkinitrd initrd-2.6.21-prep.img 2.6.21-prep
step 7:modify /boot/grub/menu.lst
step 8:reboot
#shutdown -r now
