Windows 2.1x
Windows 2.1 is a release of Microsoft Windows. It was released to manufacturing on May 27, 1988, as a successor to Windows 2.0. It was released with two different variants with differing CPU compatibility, also known as Windows/286 and Windows/386, so the versions are considered to be similar to its predecessor. In comparison, the Windows/386 variant is considered to be better than Windows/286, since it provides support for EMS emulation and is designed to use both conventional and extended memory. Changes to the user interface did not occur in this version, and rather, its performance was increased and enhanced memory management was added. The version is also noted to be the first one to require a hard disk drive. A minor update version, Windows 2.11, was released in March 1989. Enhancements that were introduced were considered to have improved the operating environment, while the Windows/386 variant was noted to have a good level of functionality. It was considered to ...

HIMEM
HIMEM.SYS is a DOS device driver which allows DOS programs to store data in extended memory according to the Extended Memory Specification (XMS). The memory beyond the first 1 MB of address space is required by Windows 9x/ Me in order to load; therefore, these versions of Microsoft Windows require HIMEM.SYS to be loaded to be able to run. HIMEM.SYS was first included with Windows 2.1 (1988). In MS-DOS 5.0 (1991) and later, HIMEM.SYS can be used to load the DOS kernel code into the High Memory Area (HMA) to increase the amount of available conventional memory by specifying DOS=HIGH in CONFIG.SYS. In DR DOS 5.0 (1990) and 6.0 (1991), the driver is named HIDOS.SYS rather than HIMEM.SYS, like the corresponding DCONFIG.SYS or CONFIG.SYS directive HIDOS=ON. In FreeDOS, the matching file is named HIMEMX.SYS and can be loaded from the FreeDOS configuration file named FDCONFIG.SYS or CONFIG.SYS. It is also plug compatible with MS-DOS HIMEM.SYS, offering additional contr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DESQview
DESQview (DV) is a text mode multitasking operating environment developed by Quarterdeck Office Systems which enjoyed modest popularity in the late 1980s and early 1990s. Running on top of DOS, it allows users to run multiple programs concurrently in multiple windows. Desq Quarterdeck's predecessor to DESQview was a task switching product called Desq (shipped late April or May 1984), which allows users to switch between running programs. Quarterdeck revamped its package, bringing multitasking in, and adding TopView compatibility. DESQview was released in July 1985, four months before Microsoft released the first version of Windows. It was widely thought to be the first program to bring multitasking and windowing capabilities to DOS; in fact, there was a predecessor, IBM TopView, which shipped March 1985. Under DESQview, well-behaved DOS programs can be run concurrently in resizable, overlapping windows (something the first version of Windows cannot do). A simple hideable ...

SmartDrive
SmartDrive (or SMARTDRV) is a disk caching program shipped with MS-DOS versions 4.01 through 6.22 and Windows 3.0 through Windows 3.11. It improves data transfer rates by storing frequently accessed data in random-access memory (RAM). Early versions of SmartDrive were loaded through a device driver named . Versions 4.0 and later were loaded through an executable file named , which could be run at user's discretion or at boot time via . However, also includes a double-buffering driver that should be loaded through . Version 4.0 also introduced 32-bit disk access and could reduce its footprint in conventional memory (the first 640 kilobytes of memory which was critical to DOS) by running in upper memory area (the 384 kilobytes of memory located beyond the conventional memory). A cloaked variant of SmartDrive utilizing the Helix Cloaking API was available from Helix Software.

Virtual 8086 Mode
In the 80386 microprocessor and later, virtual 8086 mode (also called virtual real mode, V86-mode, or VM86) allows the execution of real mode applications that are incapable of running directly in protected mode while the processor is running a protected mode operating system. It is a hardware virtualization technique that allowed multiple 8086 processors to be emulated by the 386 chip. It emerged from the painful experiences with the 80286 protected mode, which by itself was not suitable to run concurrent real-mode applications well. John Crawford developed the Virtual Mode bit at the register set, paving the way to this environment. VM86 mode uses a segmentation scheme identical to that of real mode (for compatibility reasons), which creates 20-bit linear addresses in the same manner as 20-bit physical addresses are created in real mode, but are subject to protected mode's memory paging mechanism. Overview The virtual 8086 mode is a mode for a protected-mode task. Conseq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
