Commodore C286-LT

Hi guys, Wanting to run the older Unices, I hunted around for a working 286. I sort of succeeded, except for the part that the sealant from the original Connor harddisk probably didn't get enough air where the laptop was situated for the past ten years and had gone fluid. Messy. Got me another harddisk, also an old Connor, not sure if it works but can't seem to find anything like a working DOS floppy with a FDISK.EXE which allows the removal of non-DOS partitions. A guy at work had a working copy of Partition Magic on floppy, but it seems to have a heavy case of floppy rot so it won't boot. So I was wondering, anyone have a floppy .img which I can rawrite or dd to a floppy to see if I can partition the old Conner or another 2,5" disk proper, so I can at least install MS-DOS onto it and maybe some old Unices later on? Thanks in advance and re, Sander
