Microsoft’s first operating system, MDOS/MIDAS, was designed along many of the PDP-11 features, but for microprocessor based systems. MS-DOS, or PC DOS when supplied by IBM, was designed to be similar to CP/M-80. Each of these machines had a small boot program in ROM which loaded the OS itself from disk.
