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 ...
Since the RD (RMDIR) command can not delete a directory if the directory is not empty (except in Windows NT & 10), the DELTREE command can be used to delete the whole directory. The deltree command is included in certain versions of Microsoft Windows and MS-DOS operating systems .
The environment of an EXE program run by DOS is found in its Program Segment Prefix.. EXE files normally have separate segments for the code, data, and stack. Program execution begins at address 0 of the code segment, and the stack pointer register is set to whatever value is contained in the header information (thus if the header specifies a 512 byte stack, the stack pointer is set to 200h).
Bochs runs on many host operating systems, including Android OS, Linux, macOS, PlayStation 2, Windows, and Windows CE along with its derivatives. Bochs is mostly used for operating system development (when an emulated operating system crashes , it does not crash the host operating system, so the emulated OS can be debugged ) and to run other ...

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).
DOSEMU is an option for people who need or want to continue to use legacy DOS software; in some cases virtualisation is good enough to drive external hardware such as device programmers connected to the parallel port. According to its manual, "dosemu" is a user-level program which uses certain special features of the Linux kernel and the 80386 ...
Spark is an open-source instant messaging program (based on the XMPP protocol) that allows users to communicate in real time. [4]It can be integrated with the Openfire server to provide additional features [5] such as controlling the various Spark functionalities from a central management console or integrating with a proprietary customer support service known as Fastpath which allows its ...
