mkinitrd <-- creates an initrd image for a given kernel.
Usually only needed by systems running SCSI to preload the necessary scsi
modules so the kernel knows how to use the hardware to load up.
On my IDE systems I've had to make sure that ext3 was compiled into the kernel
(not as a module) to get new kernels to load. I don't use initrd images on
those systems.

In the doc it says to copy over the bzImage as vmlinux-2.4.19, so I did.When I added the new entry into grub.conf I noticed that I didn't have a vmlinuz-<version> and initrd-<version> in /boot. These must be necessary as I can't boot to 2.4.19.
