Later versions of CP / M ( as well as Concurrent CP / M, Concurrent DOS, DOS Plus, Multiuser DOS, System Manager and REAL / 32 ) come with an XIOS ( Extended Input / Output System ) instead of the BIOS.

In January 1985, Digital Research previewed the Concurrent DOS 286 operating system made in cooperation with Intel.

This worked on the B-1 prototype step of the chip, but Digital Research discovered problems with the emulation on the production level C-1 step in May, which would not allow Concurrent DOS 286 to run 8086 software in protected mode.

The release of Concurrent DOS 286 was delayed until Intel would develop a new version of the chip.

In August, after extensive testing E-1 step samples of the 80286, Digital Research acknowledged that Intel corrected all documented 286 errata, but said there were still undocumented chip performance problems with the prerelease version of Concurrent DOS 286 running on the E-1 step.

Named IBM 4680 OS, IBM originally chose DR Concurrent DOS 286 as the basis of their IBM 4680 computer for IBM Plant System products and Point-of-Sale terminals in 1986.

The same limitations affected Digital Research's FlexOS 286 version 1. 0, a derivation of Concurrent DOS 286, developed in 1986, introduced in January 1987, and later adopted by IBM for their IBM 4690 OS.

Similar functions were also available under MP / M, Concurrent DOS, Multiuser DOS and FlexOS.

* L :-Dynamically assigned load drive under Concurrent DOS, Multiuser DOS, System Manager and REAL / 32.

* M :-Drive letter for optionally memory drive MDISK under Concurrent DOS., Multiuser DOS, System Manager and REAL / 32 will dynamically assign a drive letter L: to the load path of a loaded application, thereby allowing applications to refer to files residing in their load directory under a standardized drive letter instead of under an absolute path.

Linux filesystem drivers do not at present incorporate support for file / directory passwords on FAT12 / FAT16 / FAT32 volumes and multi-user world / group / owner access permissions for read / write / delete / execute rights on FAT12 / FAT16 volumes as implemented in various operating systems of the Digital Research family, including DR-DOS, PalmDOS, Novell DOS, OpenDOS, FlexOS, Concurrent DOS, Multiuser DOS, System Manager and REAL / 32.

It was originally developed by Gary Kildall's Digital Research and derived from Concurrent PC DOS 6. 0, which was an advanced successor of CP / M-86.

Digital Research fought a long losing battle to promote CP / M-86 and its multi-tasking multi-user successor Concurrent CP / M-86, and eventually decided that they could not beat the Microsoft-IBM lead in application software availability, so they modified Concurrent CP / M-86 to allow it to run the same applications as MS-DOS and PC DOS.

Initially, Digital Research developed DOS Plus 1. 2 to 2. 1, a stripped-down and modified single-user derivative of Concurrent DOS 4. 1 and 5. 0, which ran applications for both platforms.

In 1985, soon after the introduction of the Intel 80286, Digital Research introduced a real-time system, initially called Concurrent DOS 286 and subsequently FlexOS.

Digital Research also produced a multi-user multitasking operating system compatible with CP / M-86, MP / M-86, which later evolved into Concurrent CP / M-86.

An evolution of the older Concurrent CP / M-86 and Concurrent DOS operating systems, it was originally developed by Digital Research and later acquired and further developed by Novell.

Another interesting usage of LOADALL, laid out in the book The Design of OS / 2, would have been to allow running former real mode programs in 16-bit protected mode, as utilized by Digital Research's Concurrent DOS 286 since 1985 as well as FlexOS 286 and IBM 4680 OS since 1986 / 1987.

Early PC operating systems such as MS-DOS and PC DOS, did not support multitasking at all, however alternative operating systems such as MP / M-86 ( 1981 ) and Concurrent CP / M-86 did support preemptive multitasking.

Later DOS versions natively supporting preemptive multitasking / multithreading include Concurrent DOS, Multiuser DOS, Novell DOS ( later called Caldera OpenDOS and DR-DOS 7. 02 and higher ).

The DOS Plus, FlexOS and DR DOS families of operating systems started as derivations of Concurrent DOS.

It ran the VME operating systems, and supported emulation of both the earlier architectures ( 1900 Series and System 4 ), either standalone ( DME, Direct Machine Environment ) or concurrently with native-mode operation ( CME, Concurrent Machine Environment ).

Other MS-DOS / PC DOS-compatible operating systems such as DR DOS 3. 31 and higher, PalmDOS, Novell DOS, and OpenDOS, FlexOS, 4680 OS, 4690 OS, Concurrent DOS, Multiuser DOS, Datapac System Manager and IMS REAL / 32 support read / write / execute / delete file / directory access permissions on FAT volumes.

The Concurrent Versions System ( CVS ), also known as the Concurrent Versioning System, is a client-server free software revision control system in the field of software development.

* Concurrent Versions System, a revision control system for software development

It will use the Concurrent Employment component of the SAP human resource system.

Successive revisions of this system, which gradually supported MS-DOS applications and the FAT filesystem, were labelled Concurrent DOS, Concurrent DOS XM and Concurrent DOS 386.

* Concurrent Input / Output, a file systems feature introduced in JFS ( file system ) in May 2003

When an emulator was added to provide PC DOS compatibility, the system was renamed to Concurrent DOS, which later became Multiuser DOS.

As the Concurrent and countercurrent exchange mechanisms diagram shows, a concurrent exchange system has a variable gradient over the length of the exchanger.

Concurrent user licensing allows firms to purchase computer systems and software at a lower cost because the maximum number of concurrent users expected to use the system or software at any given time ( those users all logged in together ) is only a portion of the total system users employed at a company.

In 2005, Tim Harris, Simon Marlow, Simon Peyton Jones, and Maurice Herlihy described an STM system built on Concurrent Haskell that enables arbitrary atomic operations to be composed into larger atomic operations, a useful concept impossible with lock-based programming.

When Novell abandoned the system, the three Master Value Added Resellers ( VARs ) Datapac Australasia, Concurrent Controls and Intelligent Micro Software took over and continued independent development into Datapac Multiuser DOS and System Manager, CCI Multiuser DOS, and IMS Multiuser DOS and REAL / 32.

This, and the fact that some users were not moving to the new system, led ICL to develop a system called Concurrent Machine Environment ( CME ) under which VME ran DME as a subsystem, enabling 1900 and System 4 applications to be run on a 2900 or Series 39 machine alongside VME applications.
