to much for me...Take a look at the older version of the DOS source changed. Its a lot of files in there. At least this gives you what to expect. Maybe you can just look at the MSDOS folder (not the windows one), you won't see the MSDOS folder in 92 cause its not out yet, take a look at older version. If you don;t have it, download the MSDOS support for it, so you can take a peek at it.
