If you want to recompile your kernel from the source, to add or remove functions, you can use that file to start with a configuration exactly as you currently have, and then make the modifications. You don't need this file to boot.<BR /><BR />The initrd file is an "initial ram disk", it contains modules/drivers that allows the kernel to find and mount the root file system, for example, LVM modules, SCSI adapter modules, etc.<BR /><BR />The vmlinuz file is the kernel itself.
