Thanks for the suggestion (and I did look into Tom's), but I'd like to try it with grub.
I found a site that has a 'walk-through' on how to build a floppy similar to what I want at
I've tried it, but as with many of my attempts, I always get the same error once I boot from one of these 'single floppy' linuxes:
Kernel panic: VFS: Unable to mount root fs on 01:00
If anyone knows why I might be getting this, please let me know.
