Older Operating Systems
Older Operating Systems Class Notes # 14 Computer Configuration November 20, 2003 The default configuration of DOS, which may be adequate for many users, is intended to work with the greatest number of systems. DOS also allows users to take full advantage of their computers features. We could configure our computer to operate more efficiently. There are two general ways of making our computers efficient: • Add or replace hardware • Use software to attain an optimal configuration for existing hardware resources DOS falls in the second category. With DOS we can manage our memory more efficiently and we can also use special device drivers and utility programs to enhance the performance of our hardware and software. Device Drivers Device drivers are software programs, which is used by DOS to control hardware devices. Most device drivers are loaded at boot time by including the device driver in your CONFIG.SYS. The DEVICE command tells DOS to load a device driver and uses the following syntax: DEVICE = driver /switches The driver is the actual software for the device, and the /switches are any switches that the device driver software needs. For example, the mouse device driver (MOUSE.SYS) is loaded in the CONFIG.SYS file with this command: DEVICE = C:\DRIVERS\MOUSE.SYS The DEVICE = command tells DOS that the program file name MOUSE.SYS stored in the \DRIVERS directory on drive C is a TSR needed to drive the mouse device. You may also load certain device drivers in AUTOEXEC.BAT. For example, the mouse device driver can also be loaded from the AUTOEXEC.BAT file. -

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.
