But anything different from the standard formats, e.g. 360kB, 1.2MB, 1.44MB etc. (there are some other formats available as well) will not be recognized by DOS as a valid floppy disk. However, if you want to select your own ram disk size, you can still use the -c option to mknbi-dos and let it simulate a hard disk. I will tell you when I have implemented some mechanism for selecting the floppy image size. gero. -- It takes a smart man to know when he's stupid. - Barney Rubble -- Gero Kuhlmann, Hannover 0511/6497525 (Voice) gero@gkminix.han.de
