Well, I still don't know why Your PC can boot Spinrite from flash storage but seemingly nothing else. Therefore I don't yet have an answer.

Sorry, I can't help you there either. The only PC (Laptop) with a floppy drive I still have does not have usable USB ports. But I remember to be able to write boot floppies for/from a Linux Installation on the internal hard disk of that laptop. That was a nice way to preserve boot loaders of other OS on the HDD of the laptop.
Knoppix still comes with the needed tools, I think: fdformat and grub-mkrescue (or grub-mkimage) might be the ticket for that. Perhaps other forum members can help you to find and test a procedure for making a Knoppix 7.0.5 boot floppy?
