Just how much code does this take, and where can I
find source?
MS-DOS 1.0 needed 16K of RAM.
Full description, but NOT source code, is in the appendix of the MS/PC-DOS
manuals from 1.0 - 2.00. After that, there was an appendectomy, and the
appendix (still with "appendix #" page numbers) was sold separately as the
DOS Technical Reference Manual.
Are you using an 8086 family processor?
There are a number of commercially available packages with source for an
OS, such as Caldera Open-DOS (formerly DR-DOS, formerly CCP/M, etc.)
Now, WHAT are you trying to do?
