[SLE] Recover Boot Partition

Hello List, Is it possible to recover a corrupted boot partition/sector. If so any links to detailed instruction or info would be much appreciated. I'm running SuSE 7.3/Kernel 2.4.10. I'd like to get the boot sector repaired without formating the drive. Currently the system is back up, booted from LiLO on a floppy. -rickey
