Installing Smart Boot Manager on floppy

(Have tried posting in comp.os.linux.setup, but so far to no avail.)

Looking for a replacement for GAG** as boot manager, I've looked at PLOP
and SBM.

Preferring to check them out on floppy first before committing to MBR, I
first looked at PLOP.
This worked fine from floppy, but then I discovered it cannot handle
Logical partition numbers > 4, so had to forget PLOP.

With SBM on the other hand, although I've tried different sources of
sbmdisk.img, and different floppies, after writing it to floppy:

$ dd if=/home/mab/Download/sbm.img of=/dev/fd0
216+0 records in
216+0 records out
110592 bytes (111 kB) copied, 7.10425 s, 15.6 kB/s

Result: When booting from the floppy the system freezes after a
couple of floppy 'read' blips (screen stays blank) and it's restart
time...

If anyone here has had success with SBM I would very much appreciate
some hints as to how to get the thing working...

(** Currently I'm booting with GAG on floppy, as it cannot find device
x'80 to write to MBR.)
