cannot boot suse after kernel upgrade (just a little help required)

Hi list, I ****ed up and didn't execute mk_initrd and/or lilo after a rpm update of my kernel. Now when I boot my (SCSI) system, I get: RAMDISK: Couldn't find valid RAM disk image starting at 0. request_module[block-major-8]: Root fs not mounted VFS: Cannot open root device 08:01 Kernel panic: VFS: Unable to mount root fs on 08:01 what's the best method to rescue this machine? Thanks in advance for any help/advice re this problem. Michael
