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.
