Virtual DOS machines can operate either exclusively through typical software emulation methods (e.g. dynamic recompilation) or can rely on the virtual 8086 mode of the Intel 80386 processor, which allows real mode 8086 software to run in a controlled environment by catching all operations which involve accessing protected hardware and forwarding them to the normal operating system (as exceptions).
MASM 6.1 and the 16-bit version of the Visual C++ 1.0 compiler were Win32 applications written for a beta version of Windows NT that was bound with the TNT DOS Extender. The Win32 executables referenced functions such as RtlExAllocateHeap in ntdll.dll, which did not exist in the final ntdll.dll, so if Windows even allowed you to run it (with a ...
Upon the release of Windows 10 in 2015, the ARM-specific version for large tablets was discontinued; large tablets (such as the Surface Pro 4) were only released with x86 processors and could run the full version of Windows 10. Windows 10 Mobile had the ability to be installed on smaller tablets (up to nine inches); [16] however, very few such ...
Concurrent DOS 286, Concurrent DOS 68K and FlexOS were designed by Francis "Frank" R. Holsworth (using siglum FRH). [5] [6] Like Portable CP/M, Concurrent DOS 286, Concurrent DOS 68K and Concurrent DOS V60, [1] [7] FlexOS was written in C for higher portability across hardware platforms, and it featured very low interrupt latency and fast context switching.
VM/386 is a multitasking Multi-user environment or 'control program' [1] that took early advantage of the capabilities of Intel's 386 processor. By utilizing Virtual 8086 mode, users were able to run their existing text-based and graphical DOS software in safely separate environments.
In other words, Phar Lap created an OS/2 compatibility box for DOS. A 16-bit protected-mode DOS application can be built by compiling it with Microsoft C under DOS, specifying that an OS/2 program should be built, and then executing the resulting file on DOS with the aid of 286|DOS-Extender. With Lotus and Microsoft using DOS extenders, an ...
dbDOS is software developed by dBase for Windows computers with Intel processors. dbDOS allows Intel-based PCs to run DOS Applications, such as dBASE III, dBASE IV (Version 1, 2, 3), and dBASE V for DOS in an emulated DOS environment. It is an environment configured specifically to allow the various versions of dBASE for DOS to run without any ...
Windows installs its own version of HIMEM.SYS [15] on DOS 3.3 and higher. Windows HIMEM.SYS launches 32-bit protected mode XMS (n).0 services provider for the Windows Virtual Machine Manager, which then provides XMS (n-1).0 services to DOS boxes and the 16-bit Windows machine (e.g. DOS 7 HIMEM.SYS is XMS 3.0 but running 'MEM' command in a ...
