Hello, I try to integrate MsDos 6.22 to my CDShell based Multi-boot DVD but with no result... This is the solution I try: I have created an 4MB disk image containing the files of the 3 MsDos disks. To boot this image, I need bcdw http://bootcd.narod.ru/. I have added the bcdw.scm file to the modules directory of cdshell. And in my cdshell.ini, I have added bcdw \IMG_BOOT\MSDOS622.IMG But it say : Error: Unknown command entered. [Command: bcdw] Do you now why bcdw in not recognized?
