IBM computers had BASIC 1.1 in ROM, and IBM's versions of BASIC used code in this ROM-BASIC, which allowed for extra memory in the code area. BASICA last appeared in IBM PC DOS 5.02, and in OS/2 (2.0 and later), the version had ROM-BASIC moved into the program code. Microsoft released GW-BASIC for machines with no ROM-BASIC. Some OEM releases ...
An optional return code can be given, otherwise 0 is assumed. RMSIZE (OS/2 [nb 3] only, ignored under DR-DOS 7.02 and higher) Defines the real mode memory size. RUN (OS/2 [nb 3] only) Similar to CALL, loads programs in CONFIG.SYS. Similar to INSTALL under DOS and CALL under OS/2, but loads programs in background concurrently. SAVENAME (PTS-DOS ...
When the DOSBox application is opened, it automatically mounts to a virtual, permanent [24] Z: drive that stores DOSBox commands and utilities. [28] The reasons for the virtual drive are related to security, [ 29 ] but the user can mount a different drive letter in the emulator to a directory, image file, floppy disk drive, or CD-ROM drive on ...
FreeDOS can be booted from a floppy disk or USB flash drive [7] [8] and is designed to run well under virtualization or x86 emulation. [ 9 ] The FreeDOS project began under Jim Hall in 1994, and the first stable version was released in 2006.

A DOSBox window pops up when I run the game and it seems likely that some of the other EA/Origin classic games--such as the Ultima series--also uses DOSBox. With the popularity of classic games doing well on things such as Nintendo's Virtual console, it looks like even more PC game developers are jumping on the classic game bandwagon.
[26] [27] DOSBox is designed for legacy gaming (e.g. King's Quest, Doom) on modern operating systems. [17] [26] DOSBox includes its own implementation of DOS which is strongly tied to the emulator and cannot run on real hardware, but can also boot MS-DOS, FreeDOS, or other DOS operating systems if needed.
Novell DOS 7, Caldera OpenDOS 7.01 and DR-DOS 7.02 and higher provide a functional equivalent to MSCDEX named NWCDEX, which also runs under MS-DOS and PC DOS.It has more flexible load-high capabilities, also allowing to relocate and run in protected mode through DPMS on 286 and higher processors, thereby leaving only a 7 KB stub in conventional or upper memory (in comparison to MSCDEX, which ...
