If you use a turbo R computer or a MSX-DOS 2 cartridge, the formatting will be different if you boot with DOS2 enabled or disabled. Besides, it must be a MSX2 with at least 128kB RAM if you use a MSX-DOS 2 cartridge without built-in memory mapper. This cartridge requires at least a MSX2 computer with internal or external disk drive. The MSX however does not support sub-directories, unless you use an MSX turbo R computer, the original MSX-DOS2 cartridge or one of its European versions.
