NetWare Loadable Module
A NetWare Loadable Module (NLM) is a loadable kernel module (a binary code module) that can be loaded into Novell's NetWare operating system. NLMs can implement hardware drivers, server functions (e.g. clustering), applications (e.g. GroupWise), system libraries or utilities. NLMs were supported beginning with the Intel 80386-based NetWare version 3.x. Prior versions of NetWare had a monolithic kernel, and significant hardware or functionality changes required re-linking the kernel from object modules. Due to stability issues with early third-party NLMs, they never became popular for server application programming, with few exceptions like antivirus programs, backup programs and certain database products. Functionality Upon loading, a NLM requests resources, such as memory and process threads, from the NetWare kernel. The NetWare kernel tracks such requests, and can identify memory and other resources assigned to a specific NLM. NLMs may auto-load other NLMs upon which ...

Novell
Novell, Inc. was an American software and services company headquartered in Provo, Utah, that existed from 1980 until 2014. Its most significant product was the multi- platform network operating system known as Novell NetWare. Under the leadership of chief executive Ray Noorda, NetWare became the dominant form of personal computer networking during the second half of the 1980s and first half of the 1990s. At its high point, NetWare had a 63 percent share of the market for network operating systems and by the early 1990s there were over half a million NetWare-based networks installed worldwide encompassing more than 50 million users. Novell technology contributed to the emergence of local area networks, which displaced the dominant mainframe computing model and changed computing worldwide. Novell was the second-largest maker of software for personal computers, trailing only Microsoft Corporation, and became instrumental in making Utah Valley a focus for technology and softw ...

Abnormal End
An abnormal end or abend is an abnormal termination of software, or a program crash. This usage derives from an error message from the IBM OS/360, IBM zOS operating systems. Usually capitalized, but may appear as "abend". Some common ABEND codes are ABEND 0C7 (data exception) and ABEND 0CB (division by zero).List of ABEND codes on madisoncollege.edu Abends can be "soft" (allowing automatic recovery) or "hard" (terminating the activity). page 352 Errors or crashes on the network operating system are usually called ABENDs.

Extended Memory
In DOS memory management, extended memory refers to memory above the first megabyte (220 bytes) of address space in an IBM PC or compatible with an 80286 or later processor. The term is mainly used under the DOS and Windows operating systems. DOS programs, running in real mode or virtual x86 mode, cannot directly access this memory, but are able to do so through an application programming interface called the ''Extended Memory Specification'' (XMS). This API is implemented by a driver (such as HIMEM.SYS) or the operating system, which takes care of memory management and copying memory between conventional and extended memory, by temporarily switching the processor into protected mode. In this context, the term "extended memory" may refer to either the whole of the extended memory or only the portion available through this API. Extended memory can also be accessed directly by DOS programs running in protected mode using VCPI or DPMI, two (different and incompatible) method ...

Protected Mode
In computing, protected mode, also called protected virtual address mode, is an operational mode of x86-compatible central processing units (CPUs). It allows system software to use features such as virtual memory, paging and safe multi-tasking designed to increase an operating system's control over application software. When a processor that supports x86 protected mode is powered on, it begins executing instructions in real mode, in order to maintain backward compatibility with earlier x86 processors. Protected mode may only be entered after the system software sets up one descriptor table and enables the Protection Enable (PE) bit in the control register 0 (CR0). Protected mode was first added to the x86 architecture in 1982, with the release of Intel's 80286 (286) processor, and later extended with the release of the 80386 (386) in 1985. Due to the enhancements added by protected mode, it has become widely adopted and has become the foundation for all subsequent enhancem ...

DOS Protected Mode Services
DOS Protected Mode Services (DPMS) is a set of extended DOS memory management services to allow DPMS-enabled DOS drivers to load and execute in extended memory and protected mode. Not being a DOS extender by itself, DPMS is a minimal set of extended DOS memory management services to allow slightly modified DOS resident system extensions ( RSX) such as device drivers or TSRs (as so called ''DPMS clients'') to relocate themselves into extended memory and run in 16-bit or 32-bit protected mode while leaving only a tiny stub in conventional memory as an interface to communicate with the conventional DOS environment. The DPMS clients do so through DPMS services provided by a previously loaded ''DPMS server''. The necessary size of the remaining stub depends on the type of driver, but often can be reduced to a few hundred bytes for just the header even for complex drivers. By executing the driver in extended memory and freeing up conventional memory, DPMS not only allows very large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Open Data-Link Interface
The Open Data-Link Interface (ODI), developed by Apple and Novell, serves the same function as Microsoft and 3COM's Network Driver Interface Specification (NDIS). Originally, ODI was written for NetWare and Macintosh environments. Like NDIS, ODI provides rules that establish a vendor-neutral interface between the protocol stack and the adapter driver. It resides in Layer 2, the Data Link layer, of the OSI model. This interface also enables one or more network drivers to support one or more protocol stacks.

NetWare DOS Client
NetWare Lite and Personal NetWare are a series of discontinued peer-to-peer local area networks developed by Novell for DOS- and Windows-based personal computers aimed at personal users and small businesses in the 1990s. NetWare Lite In 1991, Novell introduced a radically different and cheaper product from their central server-based NetWare product, NetWare Lite 1.0 (NWL), codenamed "Slurpee", in answer to Artisoft's similar LANtastic. Both were peer-to-peer systems, where no dedicated server was required, but instead all PCs on the network could share their resources. Netware Lite contained a unique serial number in the EXE files that prevented running the same copy on multiple nodes within a single network. This basic copy protection was easily circumvented by comparing files from different licenses and accordingly editing the serial number bytes. The product was upgraded to NetWare Lite 1.1 and also came bundled with DR DOS 6.0. Some c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Codewarrior
CodeWarrior is an integrated development environment (IDE) published by NXP Semiconductors for editing, compiling, and debugging software for several microcontrollers and microprocessors (Freescale ColdFire, ColdFire+, Kinetis, Qorivva, PX, Freescale RS08, Freescale S08, and S12Z) and digital signal controllers (DSC MC56F80X and MC5680XX) used in embedded systems. The system was developed by Metrowerks on the Macintosh, and was among the first development systems on that platform to cleanly support both the existing Motorola 68k and the new PowerPC (PPC). During Apple's transition to the PPC, CodeWarrior quickly became the ''de facto'' standard development system for the Mac, rapidly displacing Symantec's THINK C and Apple's own Macintosh Programmer's Workshop. The purchase of NeXT in 1996 led to a decline in CodeWarrior's relevance as Mac programming moved to the NeXT platform's own developer tools. Metrowerks responded by porting CodeWarrior to Microsoft Windows and introduci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metrowerks
Metrowerks was a company that developed software development tools for various desktop, handheld, embedded, and gaming platforms. Its flagship product, CodeWarrior, comprised an IDE, compilers, linkers, debuggers, libraries, and related tools. In 1999 it was acquired by Motorola and in 2005 it was spun-off as part of Freescale, which continues to sell these tools. In 2015, Freescale Semiconductor was absorbed into NXP. History Founded by Greg Galanos in 1985 as Metropolis Computer Networks in Hudson, Quebec, Metrowerks originally developed software development tools for the Apple Macintosh and UNIX workstations. Its first product was a Modula-2 compiler originally developed by Niklaus Wirth, the creator of the ALGOL W, Pascal and Modula-2 programming languages. It had limited success with this product. In 1992, it began an effort to develop development tools for Macintosh computers based on the newly announced PowerPC processor as well as legacy support for 68k chipset ...
