DR DOS 5.0 vs. MS-DOS 5 Upgrade 様様様様様様様様様様様様様様様� Digital Research is well-known for pioneering standards in operating systems for microcomputers. With the introduction of DR DOS 5.0 in May 1990, Digital Research again introduced a leading-edge technology DOS with major features that both add value and enhance any system's performance. The following is a comparison of DR DOS 5.0 and the recently announced and available MS-DOS 5 Upgrade. The following tables provide an objective analysis of the features of these products. They highlight memory management and overall system optimization, ease of use, disk management and optimization and data security and file sharing.
