While reading through /usr/doc/dosemu-0.99.13/QuickStart, it was said that ``...if you are using the DosC (FreeDos) kernel, for this you have to use 'hdimages' and ./setup-hdimage.'' Unfortunately ./setup-hdimage immediately fails since /usr/bin/dexe/check-mtools does not exist.
Fixed. You don't need to create an image, by the way - we're providing one in the dosemu-freedos package. The current version is in Rawhide powertools.
