What is patched in is the FAT superblock from the Syslinux system
volume, starting at byte 11. However, I did just notice a dangerous
thing: I always copy the number of bytes appropriate for FAT32, which is
larger than for FAT12/16. I will fix that :)
.bss is obviously only supported when booting from a FAT filesystem.
