Eliminate DOS's 640KB Memory Limit in Your 32-bit Programs

A DOS extender is a program that provides your DOS program with almost unlimited main memory by running your program in Intel's protected mode. Your program can transparently access all of the memory in today's PCs.
DOS/4G is the most widely used 32-bit DOS extender, designed to allow 32-bit DOS programmers to solve memory limitations by breaking the 640KB barrier and addressing all the memory on Intel Pentium (386 and above) machines in MS-DOS, PC-DOS, DR-DOS, the DOS boxes of Windows 3.1, 95, 98, ME, NT, 2000, XP and OS/2, and under dosemu in Linux.
Easy to use: most applications are converted in one day.

Eliminate DOS's 640KB Memory Limit in Your 16-bit Programs

DOS/16M is the premier 16-bit DOS extender, designed to allow 16-bit DOS programmers to solve memory limitations by breaking the 640KB barrier and addressing all the memory on Intel 286, Intel Pentium (386 and above) machines in MS-DOS, PC-DOS, DR-DOS, the DOS boxes of Windows 3.1, 95, 98, ME, NT, 2000, XP and OS/2, and under dosemu in Linux.
Easy to use: most applications are converted in less than a day.
