IO.SYS
is an essential part of MS-DOS and Windows 9x. It contains the default MS-DOS device drivers (hardware interfacing routines) and the DOS initialization program. Boot sequence In the PC bootup sequence, the first sector of the boot disk is loaded into memory and executed. If this is the DOS boot sector, it loads the first three sectors of into memory and transfers control to it. then: # Loads the rest of itself into memory. # Initializes each default device driver in turn (console, disk, serial port, etc..). At this point, the default devices are available. # Loads the DOS kernel and calls its initialization routine. The kernel is stored in with MS-DOS and in with Windows 9x. At this point, "normal" file access is available. # Processes the file with Windows 9x. # Processes the file, in MS-DOS 2.0 and higher and Windows 9x. # Loads (or other operating system shell if specified). # Displays the bootsplash in Windows 9x. If is present, it is used as the bootsplash. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Architecture Of Windows 9x
The Windows 9x series of operating systems refers to the kernel which lies at the heart of Windows 9x. Its architecture is monolithic. The basic code is similar in function to MS-DOS. As a 16-/32-bit hybrid, it requires support from MS-DOS to operate. Critical files Windows 95 boots using the following set of files: 32-bit shell and command line interpreter: * SHELL.DLL and SHELL32.DLL – Shell API * EXPLORER.EXE – Windows shell and file manager * COMMAND.COM – command line shell executable Windows 95 Core: * KERNEL32.DLL and KRNL386.EXE – Windows API for Windows resources * ADVAPI32.DLL Functionality additional to the kernel. Includes functions for the Windows registry and shutdown and restart functions * GDI32.DLL and GDI.EXE - Graphic device interface * USER32.DLL and USER.EXE - GUI implementation * COMMCTRL.DLL and COMCTL32.DLL - Common controls (user interface) * DDEML.DLL Dynamic Data Exchange Management Library (DDEML) provides an interface th ...

MS-DOS
MS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system. IBM licensed and re-released it in 1981 as PC DOS 1.0 for use in its PCs. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility, syntax, and capabilities. Beginning in 1988 with DR-DO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DR DOS
DR-DOS (written as DR DOS, without a hyphen, in versions up to and including 6.0) is a disk operating system for IBM PC compatibles. Upon its introduction in 1988, it was the first DOS attempting to be compatible with IBM PC DOS and MS-DOS (which were the same product sold under different names). DR-DOS was developed by Gary A. Kildall's Digital Research and derived from Concurrent PC DOS 6.0, which was an advanced successor of CP/M-86. As ownership changed, various later versions were produced with names including Novell DOS and Caldera OpenDOS. History Origins in CP/M Digital Research's original CP/M for the 8-bit Intel 8080- and Z-80-based systems spawned numerous spin-off versions, most notably CP/M-86 for the Intel 8086/ 8088 family of processors. Although CP/M had dominated the market since the mid-1970s, and was shipped with the vast majority of non-proprietary-architecture personal computers, the IBM PC in 1981 brought the beginning of what was eventual ...

List Of DOS System Files
MS-DOS / PC DOS and some related disk operating systems use the files mentioned here. System Files: *IO.SYS (or IBMBIO.COM): This contains the system initialization code and builtin device drivers. * MSDOS.SYS (or IBMDOS.COM): This contains the DOS kernel. Command-line interpreter (Shell): *COMMAND.COM: This is the command interpreter.

Windows 9x
Windows 9x is a generic term referring to a series of Microsoft Windows computer operating systems produced from 1995 to 2000, which were based on the Windows 95 kernel and its underlying foundation of MS-DOS, both of which were updated in subsequent versions. The first version in the 9x series was Windows 95, which was succeeded by Windows 98 and then Windows Me, which was the third and last version of Windows on the 9x line, until the series was superseded by Windows XP. Windows 9x is predominantly known for its use in home desktops. In 1998, Windows made up 82% of operating system market share. Internal release versions for versions of Windows 9x are 4.x. The internal versions for Windows 95, 98, and Me are 4.0, 4.1, and 4.9, respectively. Previous MS-DOS-based versions of Windows used version numbers of 3.2 or lower. Windows NT, which was aimed at professional users such as networks and businesses, used a similar but separate version number between 3.1 and 4.0. All vers ...

SYS (DOS Command)
In computing, sys is a command used in many operating system command-line shells and also in Microsoft BASIC. DOS, Windows, etc. SYS is an external command of Seattle Computer Products 86-DOS, Microsoft MS-DOS, IBM PC DOS, Digital Research FlexOS, IBM/ Toshiba 4690 OS, PTS-DOS, Itautec/ Scopus Tecnologia SISNE plus, and Microsoft Windows 9x operating systems. It is used to make an already formatted medium bootable. It will install a boot sector capable of booting the operating system into the first logical sector of the volume. Further, it will copy the principal DOS system files, that is, the DOS-BIOS ( IO.SYS or IBMBIO.COM) and the DOS kernel (MSDOS.SYS or IBMDOS.COM) into the root directory of the target. Due to restrictions in the implementation of the boot loaders in the boot sector and DOS' IO system, these two files must reside in the first two directory entries and be stored at the beginning of the data area under MS-DOS and PC DOS. Depending on version, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Remote Program Load
Remote Initial Program Load (RIPL or RPL) is a protocol for starting a computer and loading its operating system from a server via a network. Such a server runs a network operating system such as LAN Manager, LAN Server, Windows NT Server, Novell NetWare, LANtastic, Solaris or Linux. RIPL is similar to Preboot Execution Environment (PXE), but it uses the Novell NetWare-based boot method. It was originally developed by IBM. IBM LAN Server IBM LAN Server enables clients (RIPL requesters) to load the operating systems DOS or OS/2 via the 802.2/ DLC-protocol from the LAN (often Token Ring). Therefore, the server compares the clients' requests with entries in its RPL.MAP table. Remote booting DOS workstations via boot images was supported as early as 1990 by IBM LAN Server 1.2 via its PCDOSRPL protocol. IBM LAN Server 2.0 introduced remote booting of OS/2 stations (since OS/2 1.30.1) in 1992. RPL and DOS For DOS remote boot to work, the RPL boot loader is loaded into the ...
