...just thought of another way to "cheat": format the larger tracks with 
more sectors per track to gain more space, and patch the boot code 
and/or BIOS to compensate.  I never booted from such disks, but I have 
definitely screwed around with capacity successfully (for example, 
formatting a 360K disk to 410K, or a 1.4MB disk to 1.8MB, etc.).
