Boot floppy not created during HD install - not /dev/fd0.

I installed Knoppix on my laptop hard drive - all went well with the install, except when I said "yes" to create a boot floppy, it didn't happen. I think the problem is that I have an external floppy drive and knoppix-installer did not allow me to select it, instead it looked for the floppy at /dev/fd0. Is there a way that I can create a boot diskette from the install (it seems to all be there)? My next step is to set up dual boot, and I need that boot diskette to make it happen.
