DPMI stands for DOS Protected Mode Interface. It is an API that allows a program to run in protected mode on 80286 series and later processors, and do the calls to real mode without having to set up these CPU modes manually. DPMI also provides the functions for managing various resources, notably memory.This allows the DPMI-enabled programs to work in multi-tasking OSes, allowing an OS kernel ...
DPMI Vocational Institute, popularly known as DPMI works under the aegis of PMTS of India & is registered in Delhi under the SR Act 1860, Section XXI. The Institute has successfully completed 27 years in the field of imparting skill based technical education. The core intent of DPMI is to promote Paramedical Health Education, Hotel Management ...
A DOS extender is a program that "extends" DOS so that programs running in protected mode can transparently interface with the underlying DOS API.This was necessary because many of the functions provided by DOS require 16-bit segment and offset addresses pointing to memory locations within the first 640 kilobytes of memory.Protected mode, however, uses an incompatible addressing method where ...
the DPMI Committee and formulate an industry-wide standard for protected-mode DOS applications. The Committee released the first public DPMI Specification, Version 0.9, in May 1990. (See Appendix A: Glossary for the definitions of DPMI, DPMI client, DPMI host, Expanded memory, Expanded memory emulator, EMS, Extended memory, and VCPI.) 5
A DPMI host (either a Windows DOS box or CWSDPMI.EXE) provides these functions for your programs. Selectors and descriptors Descriptors are a bit like real mode segments; they describe (as the name implies) a memory area in protected mode. A descriptor contains information about segment length, its base address and the attributes of it (i.e ...

DPMI provides an interface between protected mode and real mode programs. DPMI consists of a set of protected mode functions which allow a DOS application to enter protected mode, allocate real mode memory, simulate real mode interrupts and function calls, intercept real mode interrupt vectors, etc. By using these calls, an application running ...
The DOS Protected Mode Interface (DPMI) Specification version 0.9 was created by the DPMI Committee in 1990, and extended to version 1.0 in 1991. From the introduction to the DPMI 1.0 spec, "The DOS Protected Mode Interface (DPMI) allows DOS programmers to access the advanced features of 80286, 80386, and 80486-based PCs in a well-behaved ...
Apart from DPMI testing package I met just one game optionally using it (Ultima 8 ). I tested one 16 bit DPMI client - the one probided with Borland DOS based Compilers (Borland C, Borland Pascal). It consists of about six files (DPMI*.*, RTM, RTMRES.EXE). I tested it by DPMI testing utilities after starting it by RTMRES.EXE and it seemed ok.
DPMI and VCPI enabled a program to run in extended memory. See VCPI, XMS and DOS extender. Advertisement. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.
