   This is the file .../info/DOS.nfo, which contains info
about the services unprovided by the DOS. It is intended for use by the
MOOSE developpers not to look into books each time they need this information.
It does not try to incorporate all the info about the DOS, only that needed
by MOOSE.

    Info taken from:
- The PC system programming BIBLE (Third Edition) by Michael Tischer, 1993
- Advanced MS-DOS (for version 3.2) by Ray Duncan, 1986

File: BIOS.nfo		Node: Top	Up:(MOOSE.nfo)

   This file describes the functions provided by the BIOS, the standard PC
compatible ROM based software. It is far from complete, as I fill it only
when I need some information.

* Menu:

About the DOS:
* Intro::			What is the DOS ?

Appendice:
* DOS Internals::	n	A description of BIOS functions.

Notes:
u means uncompletely documented here.
n means not documented here (yet).

* BX,CX,DX,BP,SP,CS,DS,ES are saved and restored by the BIOS functions, unless
 stated otherwise. Other registers may have been spoilt (notably SI and DI in
 real mode) or not (the behaviour with respect to 32-bit extended registers is
 not specified).
