In all, about 40 bytes of code added. The 1773 floppy booter is only
8 or 9 bytes from butting up at the end of the upper limit under
Level 2 ($1D0 bytes total), but that booter tends to take up the most
space, and additional optimizations could yield savings. Other
booters like the SCSI/IDE and others have plenty of room.
It's cool to hear the seek pattern of the floppy change during boot!
