It will never cease to amaze me how people think that using a DOS emulator does not entail learning a bit of DOS or how to deal with DOS in a more modern streamlined environment.
Thank goodness there weren't web forums back in the days when DOS was installed on most machines, because then there would be a never ending stream of questions regarding what memory ranges were suitable for EMS UMB mapping, what an UMB was, or endless configuration nitpicking to try and get another kilobyte of base memory freed up. Oh and lets not forget the endless array of boot managers, menuing systems, DOS utilities and just the fact that you had to deal with actual floppy diskettes.
These people ought to be glad they don't have to deal with that stuff. Despite all of this however, they still refuse to browse through the readme and obtain even the basic understanding on how DOSBox has streamlined the DOS experience or even understand DOS itself.
Will wonders ever cease? God forbid this poster take the time to open readme.txt in notepad and do a search for the text "freesize". Boo Hoo.
