As your system is, obviously, working. If you have a copy of Partition magic installed you could run 'create boot disks' onto (if I remember correctly) 2 floppys and pass those on to try. PM4 thro 7 give CD boot support. It's worth a try. If not you, maybe someone else you know has this?
Or try here for an evaluation copy -http://www.soft32.com/download_151.html
Best of luck.
