DOS/4G from Tenberry Software is the most widely used 32-bit DOS extender, designed to allow 32-bit DOS programs to eliminate the inherent DOS 640KB memory limit by addressing all the memory on Intel 386 and above machines in MS-DOS, PC-DOS, DR-DOS, the DOS boxes of OS/2, Windows, Windows NT and Windows 95 and DOS clones.

When this program is required by 32-bit DOS software, it must be placed in the same directory as the software's executable in order to run properly.

Requirements

• MS-DOS (or DOS clones), OS/2, Windows 9x/NT
• 386 processor
