These methods never worked for me on either BII or SS because the installer would capture all the input, similar to the thread at
http://www.emaculation.com/forum/viewtopic.php?t=5281. It sounds like that person tried to use Windows because you're able to explicitly mount a physical floppy drive on demand on the Windows port? And it sounds like he was unsuccessful. I don't know if there's a way around this but the Windows method might work -- it would require an external floppy drive and copying the images onto physical disks and for Windows-SS to recognize them on command though.
