You can get the stable/final 7.10 version (original Narech Koumar release), as wll as the new development/beta 8.00 version. 5 | 6 | 7 | About DOS/32 Advanced DOS Extender 8 | DOS/32 Advanced DOS Extender is a state-of-the-art, high-performance, high-speed, true "Plug&Play" replacement of the world's most popular DOS Extender, DOS/4GW, created by Tenberry Software (formerly Rational Systems Inc.) for WATCOM C/C++ and FORTRAN 77 compilers which allow DOS Extended applications to run in a 32-bit flat protected mode environment. 9 | DOS/32 Advanced DOS Extender provides full compatibility with WATCOM C/C++ and OpenWatcom C/C++ featuring one of the most complete software emulations of DOS/4GW, thus allowing the users to "plug" DOS/32 Advanced into the protected mode programs which use DOS/4G, DOS/4GW, DOS/4GW Professional and any other compatible DOS Extenders without the need in modifying a single line of code. 10 | DOS/32 Advanced has been designed and optimized to be the fastest, most flexible and highly compatible with other software DOS Extender. It performs mode translating operations, such as Protected to Real and Real To Protected mode switching, as fast as machine's hardware allow, and while being compatible with DOS/4GW, it is the fastest DOS Extender that supports WATCOM C/C++ at this time! A large number of configuration options allow DOS/32 Advanced to be configured in hundreds different ways, either by a special environment variable or by an external setup program, giving its users the ability to manually adjust the number of allocated selectors, callbacks, virtual stacks, turn off the exception handling, change the size of DOS transfer buffer and much, much more. Compatibility with "Clean" (also known as "Raw" or INT 15h), XMS, VCPI and DPMI system softwares allows DOS/32 Advanced DOS Extender to run on different machines with various operating systems installed. Additionally, availability of such features as Null-Pointer Protection, Extended Memory Blocks Checking and support for built-in Debug Mode turns DOS/32 Advanced into a powerful tool for protected mode programmers who want to make their 32-bit protected mode applications error-free. 11 | 12 | 13 | About DOS/32 Advanced Team 14 | The newly founded DOS/32 Advanced Team is coordinated by Javier Gutierrez, and is open to any developer that want to contribute to the project. 15 | Its intention is to improve the excellent DOS/32 Advanced DOS Extender in order to be freely available to OpenWatcom users, and also to the Watcom C/C++ legacy users by giving them a fast, small and free DOS Extender replacement for the DOS4/GW family. 16 | -------------------------------------------------------------------------------- /examples/asm_1/hello.asm: -------------------------------------------------------------------------------- 1 | ; 2 | ; Copyright (C) 1996-2002 Supernar Systems, Ltd.

As of 2022-01, the original host website at [dos32a.narechk.net](http://dos32a.narechk.net/) is no longer available, but is archived on the [Wayback Machine](https://web.archive.org/web/20210726190857/https://dos32a.narechk.net/index_en.html). 4 | 5 | The binary (dos32a-912-bin.zip) and source (dos32a-912-src.zip) archives have been unzipped over the contents of DOS/32A v8.00 Liberty Edition, retrieved from [Sourceforge.net](https://sourceforge.net/projects/dos32a/), which contains documentation, examples, and other files not included with the v9.12 release. The v8.0 release appears to have been independant of the original author, with the "press.txt" file advertising the _newly founded DOS/32 Advanced Team is coordinated by Javier Gutierrez_. 6 | 7 | DOS/32A is Copyright © 1996-2006 by Narech Koumar. 8 | 9 | ## Overview 10 | 11 | DOS/32 Advanced DOS Extender is a drop-in replacement for the popular DOS/4GW DOS Extender and compatibles. During 1990'es many software applications and games were developed using Watcom C/C++ and Fortran compilers which allowed DOS applications to run in 32-bit flat protected mode environment, e.g. be "DOS Extended." This functionality was provided by the DOS/4GW DOS Extender from Tenberry Software, a middleware product which at the time was bundled with Watcom tools. While being royalty-free, DOS/4GW was big, slow and lacked many important features, all in favour of its commercial (and rather expensive) siblings. To remedy the situation a number of independent projects set out to create a replacement of DOS/4GW that could match and exceed it in terms of features, performance and price. DOS/32A is the result of such a project. 12 | 13 | DOS/32 Advanced DOS Extender provides full compatibility with Watcom C/C++ and features one of the most complete software emulations of DOS/4GW, thus allowing the users to "plug" it into the protected mode programs which use DOS/4G, DOS/4GW, DOS/4GW Professional and any other compatible DOS Extenders without the need to modify a single line of code. 14 | 15 | DOS/32 Advanced DOS Extender has been designed to be fast, flexible and reliable. It features very fast mode translation and interrupt servicing, ability to configure and bind the DOS Extender to applications, protected mode executable compression, support for allocation of up to 2 GB of memory, Null-pointer protection and more. 16 | 17 | DOS/32 Advanced DOS Extender has been commercially available since 1996 and has been used in numerous projects targeting many different segments of software market including research, aviation, antivirus, embedded systems and dedicated real-time mission-critical software. In May 2002 DOS/32 Advanced DOS Extender was released to the public in the form of "Liberty Edition" which included the complete set of the latest binaries, documentation manuals and the complete source code of the DOS Extender and its tools under a special Apache-like license allowing unrestricted, royalty-free distribution and use of the released materials in any software projects including commercial products. 18 | 19 | ## License 20 | 21 | Redistribution and use in source and binary forms, with or without 22 | modification, are permitted provided that the following conditions are 23 | met: 24 | 25 | 1.

An additional segment, _STACK, 12 | is used by the DOS Extender as a local stack. 13 | 14 | The _ID32 segment contains DOS/32A built-in configuration which can be 15 | changed by SUNSYS Setup Utility. The segment is located at 0080h by default, 16 | and is 128 bytes long including the copyright message and time-stamp. 17 | 18 | _ID32 is followed by the _KERNEL segment, which contains DOS/32A built-in DPMI 19 | Kernel and initialization routines that determine CPU, FPU, System type 20 | (INT 15h, XMS, VCPI or DPMI) etc. It is from here DOS/32A provides DPMI 21 | services through INT 31h. 22 | 23 | _TEXT16 segment, which follows the _KERNEL, contains the main code of the DOS 24 | Extender. This segment includes initialization routines, configuration 25 | routines and entry points for extended INT 10h, INT 21h and INT 33h. It also 26 | contains the LE/LX/LC loader. 27 | 28 | When the documentation refers to "Kernel" it acually means the _KERNEL segment, 29 | likewise "Client" means the _TEXT16 segment. 30 | 31 | 32 | 33 | DOS/32A Memory Map Layout 34 | ************************* 35 | 36 | This diagram shows what the memory looks like when the DOS Extender is loaded 37 | and executed by the Operating System: 38 | 39 | 40 | Memory Area Description Length Comment 41 | ======================= ====== ======= 42 | 43 | +-----------------------+ 44 | | PSP | 0200h - Program Segment Prefix 45 | +-----------------------+ 46 | +-----------------------+ 47 | | ID32 | 0080h - DOS/32A ID32 Header 48 | +-----------------------+ 49 | *[1] | | xxxxh - DOS/32A built-in ADPMI host 50 | | Kernel | 51 | | | 52 | +-----------------------+ 53 | | | xxxxh - DOS/32A DOS Extender client 54 | | Client | 55 | | | 56 | +-----------------------+ 57 | *[2] |- Stack -| 0800h - DOS/32A internal stack 58 | +-----------------------+ 59 | | RM INT Table | 0400h - copy of Real Mode Interrupts 60 | +-----------------------+ 61 | *[3] | DPMI host data | xxxxh - present DPMI host private data 62 | // // 63 | | | 64 | +-----------------------+ 65 | | DOS Transfer Buffer | xxxxh - DOS Transfer Buffer 66 | // // 67 | | | 68 | +-----------------------+ 69 | +-----------------------+ 70 | | Free DOS Memory | xxxxh - Free DOS memory available for 71 | | | DOS programs 72 | // // 73 | | | 74 | | | 75 | +-----------------------+ 76 | 77 | 78 | 79 | [1] Kernel Note 80 | *************** 81 | 82 | When DOS/32A has recognized the system software to be DPMI, it will remove 83 | its own built-in DPMI from memory by copying the Client code (the whole 84 | segment) to the upper memory location overwriting Kernel, to free up some 85 | conventional memory.
