'''BonnyDOS''' is a system extension to [[AMSDOS]] by [[Brueggi]] of [[NoobInc.]] ([[Timo Brueggmann]]). This extension allows the use of a harddisc which is connected with the [[Symbiface]].
BonnyDOS uses it's own filesystem called [[BFS16]], but it is planned to integrate [[FAT16]] support as well.
