About DOS/32 Advanced DOS Extender

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.



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.

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.

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.
