- Microsoft's MS-DOS OEM kit (you have to become an OEM) includes
- information on how to put DOS 5.0 into ROM so that you can have a
- completely diskless system boot up DOS. Of course, you ultimately have
- to have a file system somewhere from where to obtain the programs that
- you want to run once DOS is booted. A file system skeleton that works
- out of ROM is also included. (By skeleton I mean that you probably will
- need to add code to page bits if ROM in and out, or go off into above 1
- Mbyte memory space in order to get enough ROM to hold anything of useful
- size in.)
-
- Anyway, the kit worked very well, and systems based on it are now being
- sold commercially. But, the price is that you must become a Microsoft
- OEM.
