THE BEGINNING 1/1 1 T H E BEGINNING . . . You should read this chapter even if you do not read any other. It provides important basic information to help you in using your computer. It is the minimum you nee d to know in order to sta rt work straight away.
THE BEGINNING 1/2 Turning on and booting the computer Turning the power on If you have a TV card fitted, check the chapter ‘Multimedia’ for important information. To turn on the computer, press the lower P OWER button. The green POWER ON light should come on to show that the system unit is powered.
THE BEGINNING 1/3 Caution Changing or splitting the partition on a hard disk totally erases all the programs and data recorded on that disk. Always make a backup copy of the contents of the hard disk before you start to make any serious alterations to the hard disk set-up.
THE BEGINNING 1/4 stop and then the hard drive will spin down, etc. In this mode the computer system consumes very little power at all, typically below 20W. To restart the system, press the violet ‘Standby’ button on the facia. As the monitor is in a controlled ‘off’ state, it may take a mom ent or two to fully return to normal.
THE BEGINNING 1/5 Some manufacturers still only supply their software on 3.5 inch floppy disks and these would of course have to use the floppy disk drive. Guidance on using either the CD drive, or the floppy drive, is given in chapter 2 ‘ The system drives’ .
THE BEGINNING 1/6 will close down all your applications in an orderly manner and will prompt you to save any unsaved work in the process. • You should always turn off any attached peripherals first. However, there is no need to turn off the monitor (if it is powered from the system unit).
THE BEGINNING 1/7 Do not use aerosols or sprays near any part of the system, in particular , air vents or grills, ports, or removable-media drives, as microscopic droplets can remain in the air for some time and then penetrate and cause irreparable damage.
THE BEGINNING 1/8 3. If the liquid is thin and clear, try unplugging the keyboard, turning it upside down to let the liquid drain out, and drying it for at least 24 hours at room temperature. If the keyboard does not work, call your supplier or an authorised maintainer.
THE BEGINNING 1/9 Transporting the computer Use common sense when handling the computer. Hard disks in particular can be damaged if the computer is dropped or handled roughly. As a precaution, back up you r data from the hard disks to tape or floppy disks before moving the computer.
THE SYSTEM DRIVES 2/1 2 T H E SYSTEM DRI VES This chapter contains useful information abou t the drives that are currently fitted in your computer, either behind the front drop-down panel or, in the case of the Hard drive, inside the system.
THE SYSTEM DRIVES 2/2 Disks should always be kept away from bright sunlight, dust, moisture and any strong magnetic fields, e.g. do not place them on the monitor, printer, or near a telephone. It is common to store them in a lockable “disk-box”, away from the computer itself.
THE SYSTEM DRIVES 2/3 4. The system should now be able to access the disk and the information it may contain. While the system is accessing the disk, the “drive in use” LED should be lit. Pressing the button, when the drive is not in use, will eject the floppy disk.
THE SYSTEM DRIVES 2/4 Warning The laser beam inside the CD-ROM drive is harmful to the eyes if looked at directly. Do not attempt to remove the drive cover or otherwise disassemble the CD-ROM drive.
THE SYSTEM DRIVES 2/5 To remove a compact disc, press the eject button and then lift out the CD. It is best to close the draw, to prevent dust getting in, unless you intend to put in a new CD.
THE SYSTEM DRIVES 2/6 The primary hard drive Your Apricot computer is supplied with one internal or ‘primary’ hard drive (HDD) designated as the C: drive. Windows 95 will normally be installed on this drive. Data is stored on the HDD in Directories and Subdirectories, now referred to in Windows 95 as ‘folders’.
THE SYSTEM DRIVES 2/7 DriveSpace It is possible, as an alternative to the expense of fitting a second HDD, to use disk utility software such as DriveSpace within Windows 95, which increases the usable capacity of your HDD. It can more than double the usable size of the drive using software compression technology.
SYSTEM EXPANSION 3/1 3 SYSTE M EXPANSION Your computer can accept various Expansion cards or boards. Most are simple to install with the benefit of the ‘Plug and Play’ features, explained in the guide to Windows 95. (Look out for the ‘Plug and Play’ symbol on the packaging of these add-in boards).
SYSTEM EXPANSION 3/2 Configuring the card Part of the installation procedure for many expansion cards involves setting up or configuring the card so it works correctly in the system. To configure, you assign values to various settings on the card, which enable the card to communicate with the computer.
SYSTEM EXPANSION 3/3 ISA Interrupt request level (IRQ) The interrupt request level or IRQ (the two terms are u sed interchangeably) is the line over which the expansion card sends a signal to get the attention of, or interrupt, the processor. Many of these are reserved for components on the computer’s motherboard.
SYSTEM EXPANSION 3/4 Direct memory access (DMA) channel Some hardware devices can use a DMA channel to access system memory without directly burdening the processor. Computers have DMA channels numbered DMA0 to DMA7. The following table lists the DMA channels used by the computer and shows which are available for use by expansion cards.
SYSTEM EXPANSION 3/5 I/O ports Default assignment All addresses below 100h are used by the system board for various fixed system components and chipset controller settings.
SYSTEM EXPANSION 3/6 Note Memory addresses are always written in base 16 or hexadecimal notation. Unlike the ten digits of the decimal system (0-9), hexadecimal uses sixteen digits (0-9 and A-F, where A=10, B=11, C=12 and so on up to F=15). Hexadecimal numbers are denoted either by the suffix “h” or by the prefix “0x”.
SYSTEM EXPANSION 3/7 3. At the rear of the system u nit are metal blanking plates, one for each expansion card slot. Opposite the blanking plates, at the front of the system unit, there are card guides. Th ese ensure that the front edge of a full-length card is supported securely.
SYSTEM EXPANSION 3/8 8. Position the expansion card alongside the slot in which you wish to install it. Align the rear of the card with the slot in the rear of the system unit, and, if the card is full length, align the front of the card with the card guide.
MEMORY UPGRADES 4/1 4 M E M O R Y UP GRADES Read this chapter before purchasing any memory upgrade and if in any doubt consult your supplier. T hen, if having read the relevant instructions, you still do not feel confident about installing the upgrade, you may wish to have your supplier or service organisation install it for you.
MEMORY UPGRADES 4/2 Either bank can be used first. A normal specification of 32-Bit SIMMs having an access time of 70ns for a 5V power supply applies. Parity checking (36-Bit) SIMMs are not necessary. The Electronic Data Output (EDO) type SIMMs are fully supported and will give enhanced performance, more noticeably if L2 cache is low or not fitted.
MEMORY UPGRADES 4/3 Caution If you are unfamiliar with the recommended anti-static precautions and/or the process of removing the system unit cover, refer to Appendix A, “The System Unit”.

MEMORY UPGRADES 4/5 3. The SIMMs are of the correct type It may be necessary to refit the original memory SIMMs to check if there is a problem with your new SIMMs.
MEMORY UPGRADES 4/6 Caution If you are unfamiliar with the recommended anti-static precautions and/or the process of removing the system unit cover, refer to Appendix A, “The System Unit”. 3. Identify the cache memory socket see appendix B ‘ System Motherboard’ , in conjunction with the picture below.
MEMORY UPGRADES 4/7 8. Refit and secure the system unit cover, reconnect the system and switch on. 9. Check the BIOS sign-on message to see the new value of cache memory is displayed. Adding more video memory Video memory is memory reserved for use by the on-board EVGA controller.
MEMORY UPGRADES 4/8 to touch the metal pins. These m emory chips are particularly static sensitive. Handle with extreme caution. 6. It is extremely important that the chips are fitted the right way round . Each chip has a notch at one end or small bevel at one corner, corresponding to the notch or bevel on the socket corner.
