An EMM device driver command installation line is provided which may be easily and quickly interpreted by a user, an installation or a setup program. The physical memory is correlated to the installation line by a map of the 16 K-byte DOS memory segments from 0 to the memory segment above 1024 K-bytes. Different characters are assigned to represent the different types of parameters which may be found in DOS memory (0 to 1024 K-bytes), e.g. read only memory (ROM), or video memory. Additionally, characters may represent the page (single 16 K-byte segment and frame (4 sequential pages) locations that are usable by the EMM device driver, and informative to a user. In addition to the type of characters used, the character positions also provide usable information to the user since a one to one correspondence exists between the character position and the physical locations in DOS memory.
