Eys devi ce=xans i . sys Commands to load the drivers for disk caching (VX-386) and EMS and silicon disk (VX and AX) are not present. However, the system disk contains two files, CONFIG.0OI for VX-386 models and CONFIG.002 for VX and AX models, which do contain commands for these drivers. These files are backup copies of the CONFIG.SYS on your winchester. If required, the appropriate file can be copied onto your winchester and renamed as CONFIG.SYS. 1 Mb VX and AX Models If you have a I Mb VX or AX and you want to use OS/2, Windows/386 (VX only), or other software which can make use of memory above I Mb, we advise you to contact your supplier for details of memory upgrades. EMS on the VX-386 EMS on the VX-386 is provided by installing an EMS device driver called EMM386.SYS which conforms to the Lotus, \-. Intel, and Microsoft (LIM) Expanded Memory Specification (EMS) 4.0. Release Information Note EMM386.SYS is a device driver which allows MS-DOS programs on 80386 systems to emulate expanded memory in extended memory. Installing EMM386.SYS Make sure that EMM386.SYS is loaded before any other programs that use expanded memory, such as Microsoft RAMDrive. To install EMM386.SYS, include the following command line in your CONFIG.SYS file: DEVICE=td:I tpathlem3S6.sys [size] [X:rnnm'nnrn] tl{xl [size] Specify the amount of extended memory (in Kb) for EMM386.SYS to use. The recornmended amount is 512 Kb and the default is 256 Kb. [X:mmmm-nnnn] Specify a range of memory which is not to be used for locating the EMM386.SYS page frame or other mappable pages. Only use this option if a conflict occurs; for example, if another card is using addresses between A0000 and E0000. A conflict is not likely to occur as the EMM386.SYS driver automatically searches through addresses 40000 and E0000 and can detect most cards which are using memory between these addresses. EMM386.SYS excludes the memory addresses used and does not load the page frame at these addresses. Release Information Note When EMM386.SYS finds a contiguous block of 64 Kb of free memory, it loads the EMM386.SYS page frame segment. Free memory is memory not occupied by BIOS, EGA adapters, or cards. lMxI Specify where the page frame is to be placed in memory. Only use this option to place the page frame at a specific address. EMM386.SYS automatically places the page frame for you. If EMM386.SYS detects a conflict between itself and an option card at the address you specify, a message appears. To select an address, choose a value from the following list that does not conflict with any cards that you have previously installed: Value of x Start address 0 c0000 I C4000 2 C8000 3 CC000 4 D0000 5 D4000 6 D8000 7 DCOOO E E0000 When installation finishes, a message displays the amount of expanded memory available and the address where the EMM386.SYS page frame is located. The amount of expanded memory available is the sum of the extended memory and the system memory EMM3E6.SYS has reclaimed. Release Information Note If installation is unsuccessful, EMM386.SYS displays messages describing what has happened as follows: 'Invalid parameter specified' The command line contains an option which has not been accepted. Check that you have entered the correct options (see earlier). nSize of expanded memory pool adjusted' You have requested more than the available memory using the [size] option. 'WARNING - Option ROM or RAM detected within page framen A card is using the address you have specified with the [Mx] option. 'EMM386 not installed - insufficient memoryn You need more extended memory to install EMM386.SYS. 'EMM386 not installed - unable to set page frame base address" EMM386.SYS cannot find a range of 64 Kb of free memory in the 640 Kb to I Mb range to load its page frame. 'EMM386 already installed' You cannot install EMM386.SYS twice. I Release Information Note EMS on the VX and AX YX and AX computers have built-in EMS (LIM EMS 3.2) and the driver XEMM.SYS. (Future versioni of XEMM.SYS will conform to LIM EMS 4.0.) Running XCONFIG When running the XCONFIG utility and you select the Disk parameters help text, be aware that: r You should ignore the reference to MEMM.SYS and refer to the Handbook and this release note for details of the EMS driver. r Setting the size of the silicon disk applies to XDISK.SYS and does not apply to a silicon disk created using RAMDRIVE.SYS. Using RM Mode You may see the following error message when attempting to switch your computer into RM Mode: xirhs Pc rDode driver linh,rs.sys rrct instatted or invatid driver version. This message can be produced in one of three ways: r The line ndevice=nimbus.sys'or the line ndevice=xansi.sysn is missing from CONFIG.SYS. r You are using an old version of NIMBUS.SYS which was not supplied with your computer. Release Information Note r You have attempted to enter RM Mode with your computer's built-in PVGA display adapter disabled. RM Mode and SmartDrive You are provided with the Microsoft SmartDrive disk cache utility SMARTDRV.SYS. This significantly speeds up the performance of applications by caching frequently-used data from disk into RAM and reducing the number of disk accesses required. Howevcr, you rhould rct up a diel cachc uring SmartDrivc only if you intend to opcratc your computer in IBM Mode. Do not uae SMARTDRV.SYS if you intend to urc RM Modp rincc R.lv{ Modc docc not rupport disk caching. Also, it is possible for you to damage or lose data on disks if you switch from IBM Mode to RM Mode while the SmartDrive disk cache is set up. If you wish to use RM Mode, first disable the disk cache. Note: VX-386 models are preconfigured with a I Mb disk cache. If you have one of these and wish to use RM Mode, delete the line: devi ce=smartdrv. sys I 024 from CONFIG.SYS before adding the commands to load the RM Mode drivers NIMBUS.SYS and XANSI.SYS. rc Release Information Note Memory Parity Checking ln XSETUP, if you select "Memory options' (F5) this allows you to set nMemory Parity' (Fl0) as enabled or disabled.

  • The Flashback Project: Rescuing Disk-Based Content from the 1980S to the Current Day
    IDCC16 | Research Paper The Flashback Project: rescuing disk-based content from the 1980s to the current day. Maureen Pennock Peter May Michael Day The British Library The British Library The British Library Kevin Davies Simon Whibley The British Library The British Library Akiko Kimura Edith Halvarsson The British Library The British Library Abstract This paper introduces the British Library’s Flashback project, a proof-of-concept that explored the practical challenges of preserving digital content stored on physical media (magnetic and optical disks) using a sample of content from hybrid collection items dating from between 1980 and 2010. It describes some of the activities undertaken by the project, including: the initial collection profiling and sampling of content, the extraction of content from the disks, and the project team’s experiments with identifying and applying preservation approaches to the content, which included both emulation and migration. It concludes with some general observations on the approaches taken and looks forward to the second phase of the project. Introduction The British Library is the UK’s national deposit centre for published content. Its collections are vast and comprise everything from books and journals, to maps, newspapers, electoral registers, and patent specifications, in both hard-copy and electronic form. It also contains one of the largest collections of recorded sound in the world. The Library’s digital preservation team has been working on strategies to preserve the digital elements of the collections since around 2005. Recently, attention has turned to digital content acquired before this date, content that is typically still stored on its acquisition media, with examples in the Library’s collections dating back to the 1980s.

DESCRIPTORS *Computer Assisted Instruction; Computer Networks; Computer Software Selection; Computer System Design; *Curriculum Development; Educational Needs; Foreign Countries; *Instructional Design; *Interdisciplinary Approach; Microcomputers; Secondary Education; *Urban Education IDENTIFIERS British National Curriculum; *United Kingdom ABSTRACT The program for City Technical Colleges (CTCs) draws on ideas and resources from government, private industry, and education to focus on the educational needs of inner city and urban children. Mathematics, science, and technology are at the center of the CTCs' mission, in a context which includes economic awareness and a commitment to enterprise and wealth creation. This discussion addresses the question of computer provision in the context of the need for children to learn skills in the technologies now central to their existence, and their need for sufficient access to relevant equipment through their learning experiences at school if they are to develop such skills. This paper presents a rationale for providing information technology (IT); a discussion of how subject areas in the National Curriculum, ranging from science to dance, can be enhanced by its use; suggestions for staffing and administering IT programs; and a discussion of issues concerned with system purchase, support, and maintenance.
