As usual we seem to spend to much time on non-issues... So here I am ;-)
On very small flashes with FAT12 on them you probably don't have multi
boot capabilites very simply for space reasons. On larger flashes/disks
you will have multi boot here or there but you won't have FAT12 on that
partition because it too big for it. 99.9999% chance you have FAT16 or
FAT32 on those.
Final words: This changs affects not one living soul.
[Maybe it does after all. There is a very high probablility that BDE
has got an old i386SX16 with an MFM/RLL controller and a 20MB disk
somewhere running buildworld -j16 in enless loops while measuring
interrupt latency with WITNESS enabled and testing different assembler
versions of bcopy on it and dual booting to DOS from time to time to
run some bad sector marker program] ;-)
