Does anyone know where I can get some binary files containing complete fat16 filesystems? I supposed a floppy disk image dump might work. I want to write a "small" fat16 file system handler, and it would be nice to do that independently of having to write drivers for actual hardware; I'd just debug underneath a real OS/debugger using dummy "readbyte" and such, and fill in the real details later.
