I'm not clear just when you get this error. If is as you try to boot the SBM floppy, with no chance to interact with it before this happens? Or at some other point?

It appears to install correctly, but the program will not run. I tried
installing to a bootable floppy disk, and I still get the "SBMK Bad!" error.
I also tried creating a Linux disk, and still get this error.
I made mine without even having the cwsdpmi.exe file. I doubt if this is the issue, but you might want to try without it. I also made my SBM floppy without using the -b switch. Actually this switch makes little or no sense when making a floppy anyway, as you don't install it to a bootable floppy (just a cleanly formatted floppy), and you would never use such a file to recover the MBR of a floppy anyway, you would just reformat it. My SBM floppy boots everything I try it on. You might want to try again without cwsdpmi.exe present, and without the -b option, just sbminst -t us -d 0, and just to be safe using a different floppy disk.

Making a backup file might make sense with a hard drive install, but when I installed SBM to the hard drive MBR on my test bed system I didn't bother with that either, I just installed it. I figure I can always put back a simple MBR with fdisk is the need arrises, but it never has.
