Jon, In the vDosPlus-based system, use the options menu to assign drive A: to the folder you want. Start XyWrite and make sure that the command DIR A: lists the files you expect. Shut down XyWrite. Start the program again, and use the Options menu to edit autoexec.txt. At the bottom of the file, change b: to a: wherever needed to start your own system Clipboard exchange will absolutely NOT work unless you leave drive B: exactly as it is, and you copy either the entire XY4.KBD from B:\XY4 to your own system, or carefully copy the four lines in B:\XY4\XY4.KBD that have �emendelson� above them and are numbered 46 and 47 and paste them into the corresponding places in the keyboard file in your own A: setup.
