Ramcram.Txt MEMORY MANAGEMENT for CD-ROM WORKSTATIONS
ramcram.txt MEMORY MANAGEMENT FOR CD-ROM WORKSTATIONS by Peter Brueggeman Scripps Institution of Oceanography Library University of California San Diego "Memory management for CD-ROM workstations, Part II", CD-ROM PROFESSIONAL, 4(6):74-78, November 1991. "Memory management for CD-ROM workstations, Part I", CD-ROM PROFESSIONAL, 4(5):39-43, September 1991. The nature of the memory in IBM compatible microcomputers can be confusing to understand and worse to manage. If you are lucky, everything runs fine on the CD-ROM workstation or network and an article on memory management will be interesting but lack immediacy. Try to load other software concurrent with CD-ROM software or to implement network access and you may be due for a crash course in DOS memory, its limitations, and management. Running CD-ROM software usually demands considerable memory resources. Software in general has become more memory-hungry with time, and CD-ROM software have a reputation for being very hungry. Many CD-ROM products state that 640K RAM memory is required; this is not the exact memory requirement of the CD-ROM software. The CD-ROM software itself uses some of the 640K RAM as does DOS. Rarely will the exact memory requirement of a CD-ROM software be readily accessible. Sales representatives usually will not know it and only experienced technical support staff may know. CD-ROM workstation/network managers should try to learn the exact memory requirement of their CD-ROM software. Knowing their memory requirement helps greatly in selecting the level of solution(s). Addressing memory shortfalls may involve considerable tinkering and patience and involve seemingly endless rebooting. -
Bill Gates' Original Dream When He Created Microsoft Was to Have
Bill Gates’ original dream when he created Microsoft was to have “a computer on every desk and i n every home, all running Microsoft software.” Clearly, he accomplished that goal. Depending on whose statistics you want to believe, Windows has a market share in the high 80% - low 90% rang e. So, unless you run Linux or prefer Mac OS X, chances are you’re a Windows user. When it comes to desktop operating systems, your choices are really pretty narrow. You either run Windows, or you do some Unix-like OS. There are the 12,000 different Linux distributions. There’ s always FreeBSD if you prefer your Unix without a Finnish flavor. You could go the vendor route and run AIX or HP-UX. Sun has Solaris, and as much as you might want to, you can’t forget SCO. And of course, there’s always Mac OS X. Although it may sound like variety when it comes down to it, it’s still Windows vs. Unix. There are other options, or at least there USED to be. Here are a list of five of the best operating s ystems that you probably never used. OS/2 No discussion can be had of Microsoft alternatives without mentioning OS/2. Until Microsoft ship ped Windows 2000 Professional, OS/2 4.0 was probably my desktop OS of choice. For the purpos es of this section, I’m referring to OS/2 2.0 and later, not IBM and Microsoft’s ill fated OS/2 1.x s eries. IBM billed OS/2 as being a “Better DOS than DOS” and a “Better Windows than Windows”. -

The new standard requires faster timing speeds, and runs faster than PCI. Most DOS software packages would support it as a de facto display standard , but DOS provided no graphics support, so every program manipulated the board's registers and video memory directly via special drivers. The operating system distribution software also included a relocating assembler and linker. Users said they don't need its large disk partitions, can't afford to update their existing machines, and are wary of problems with how DOS 4. Linux Today. You can find it on GitHub. Brand New. IBM had sued companies that simply copied the code. Market reaction to IBM's Enhanced Graphics Adapter has not been overwhelming, partly because the EGA's complexity—five custom chips and 12 modes—has slowed software development and the board's price tag has been a damper for many, but the EGA is emerging as the next graphics standard. Text mode is required to avoid incompatibilities video conflicts while running many popular TSR programs in graphics mode. By moving video cards from the 8-MHz, bit ISA expansion bus to the CPU's bit local bus running at full clock speed, vendors may improve high-resolution graphics performance on based PCs. -

Learn how you can Test Connection The Proof of the Pudding… by Michael Bolton The first job in which I was called a software tester was at Quarterdeck, but I was a tester there long before I had the official title. I worked in the technical support department. The company produced two interrelated products, DESQview and the Quarterdeck Expanded Memory Manager (QEMM-386). They were marketed separately, as well as together under the name DESQview 386. The age of DOS on the Intel 386 processor family was as unruly as the Wild West. Applications could write directly to the display hardware, grab control of the mouse and the keyboard by using BIOS GETTY IMAGES calls instead of going through the oper- ating system, and allocate all of the especially considering all the applica- problems with a program, we could install memory on the system without so much tions, hardware, and (non-)standards and run that program under DESQview as saying, “Excuse me.” There were a that it had to support—plus it sold like while we were on the phone, even with dozen software interfaces for accessing hotcakes, suggesting that customers all of our other programs open.
