In the past, I've used a "plop" floppy disk and cdrom to boot USB on
computers that otherwise would not allow it.

Currently the latest zip file (5.0.15) contains a 1.44mb floppy image in
the install directory; but if I recall, you mentioned a 5.25" floppy
drive so maybe this isn't the solution for you.
