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. Computers are very easy to use providing you establish a routine with a few basic disciplines[...]

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. Remember that the monitor has its own power co[...]

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. It cannot be undone afterwards !. Inexperienced or new users should take a f[...]

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. ‘Standby?[...]

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 only thing you need to know is the name of the program on the disk that does the [...]

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). • To turn off the computer, simply press the P OWER bu t[...]

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 system unit • Occasionally wipe the system unit with a soft, slightly damp, lint-free c[...]

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. 4. If a solid object drops between the keys, turn the keyboard upside down and [...]

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. (See the Hard disk section of the chapter ‘System drives’ ). D[...]

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. Using the floppy disk drive The floppy disk drive is usually configured in the system BIOS as drive A: , wit[...]

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. Avoid opening the metal window on the disk as this exposes the magnet[...]

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. Using a CD-ROM drive Unless either a second hard drive has been installed, or t[...]

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. If a fault occurs, call an authorised maintainer. Keep CDs well away from dust, moisture and temperatu re extremes and avoid touching the surface of th[...]

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. Do not attempt to move the computer while a CD is in the drive, as serious damage may be caused to both the CD and the drive, especially if the drive is acti[...]

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’. More details on directories a[...]

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. See the Windows 95 HELP for details[...]

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). You can extend the capabilities of the comp[...]

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. The chosen settings MUST be registered in the [...]

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. Some interrupts are fixed, other[...]

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. DMA Default[...]

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. They are unavailable for use. 1F0h-1F7h Hard disk drive controller 200h-207h Game I/O 278h-27Fh Parallel port 2 2B0h-2DFh Alternate VGA 2F8h-2FFh Serial port 2 378h-37Fh Paralle[...]

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”. The final digit of a [...]

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. 4. First decide in which of the available slots you wish to install [...]

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. 9. Slide the card into the slot ensuring that the card edge connector engages correctly wit[...]
