Your kernel has no ramdisk support. That's mind-numbingly stupid but I'll allow it if you're planning to use a failsafe kernel. Are you?
How do I get ramdisk support into my kernel?
Solved! Go to Solution.

SolutionYou're going to have to build a new kernel. THe option you need to add is CONFIG_BLK_DEV_RAM which is sitting under the "Block devices" section if you use one of the "GUI" configuration tools.
If you have never done a kernel compilation before it's not tough and goes something like this (directories may change a bit for Red Hat because they haven't a clue how to design a unix system but anyway)
become root
# export DISPLAY=:0
# cd /usr/src/linux (or where ever it is in Red Hat these days)
# make xconfig
navigate around until you find the bit you want change (I'd recommend not having it as module support)
change it to "y"
save and exit
# make dep
# make bzImage
# make modules
# make modules_install
# cp /boot/System.map /boot/system.map.prev
# cp /boot/vmlinuz /boot/vmlinuz.prev
# cp arch/i386/boot/bzImage /boot/vmlinuz
# cp System.map /boot/System.map
edit /etc/lilo.conf or grub.conf to include a n entry for your backup kernel image (vmlinuz.prev) or forget this if you like living dangerously
run either lilo or grup as required
# cross fingers
# re-boot

Re: ramdisk

you need to look for the CONFIG_BLK_DEV_RAM in your kernel configuration file, this should be set to y
CONFIG_BLK_DEV_RAM=y
Tell us about you progress.

Re: ramdisk
P.S. I was kind of concerned that you might have missed the "lilo" bit out as it wasn't too clear. Forget that bit and your machine won't boot (assuming you use lilo of course).
