  • Page 34 EXPANSION CARDS Expansion cards (also known as expansion boards, controllers or adapters) are small self-contained circuit boards which extend the capabilities of the computer. For example, a graphics card could provide more specialised video functions than those offered by the on-board video system, or a modem card could provide a connection to the Internet via a telephone line.
  • Page 35 E x p a n s i o n C a r d s Configuring the card Part of the installation procedure for an expansion card involves setting up or “configuring” the card so it will work correctly in the computer.
  • Page 36 E x p a n s i o n C a r d s ISA Interrupt request level (IRQ) The “interrupt request level” or “IRQ” is the means by which the expansion card sends a signal to get the attention of, or interrupt, the processor.
  • Page 37 E x p a n s i o n C a r d s Base memory address Some expansion cards are fitted with memory of their own, usually read-only memory (ROM) containing functional extensions to the computer’s BIOS (basic input/output system) ROM. Some cards also have random-access memory (RAM).
  • Page 38 E x p a n s i o n C a r d s Installing the card Read all these instructions through before attempting to install any expansion card. WARNING Never carry out any work inside the computer with AC power applied.
  • Page 39 E x p a n s i o n C a r d s 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.
  • Page 40 E x p a n s i o n C a r d s Reserving ISA legacy resources If you have just installed an ISA card, your first task after turning on the computer is to run the BIOS Setup utility and reserve or exclude the legacy resources (that is, the interrupts and UMB regions) used by the card.

  • Page 57 DRIVE UPGRADES This chapter describes how to add further drives to your computer. The forward drive bay can accommodate two hard disk drives. Either drive may be of 3.5 or 5.25 form factor. These may be E-IDE drives, or SCSI drives if you have a SCSI host bus adaptor expansion card.
  • Page 58 D r i v e U p g r a d e s WARNING Never carry out any work inside the computer with AC power applied. Always shut down the computer and unplug all power cords before removing the top cover. Configuring a Hard Disk Drive (HDD) HDDs typically require configuration, perhaps by altering jumpers on the drive itself, prior to installation.
  • Page 59 D r i v e U p g r a d e s Installing in the forward drive bay To install a second (slave) hard disk drive in the forward drive bay: Turn off the computer and unplug all power cords. If there is a diskette in the diskette drive, remove it.
  • Page 60 D r i v e U p g r a d e s Installing in the rear drive bay The rear drive bay is intended for 3.5-inch SCSI hard disk drives. Turn off the computer and unplug all power cords. If there is a diskette in the diskette drive, remove it.
  • Page 61 D r i v e U p g r a d e s Windows 95 Use the MS-DOS Fdisk program to create partitions on the disk. The Fdisk program can be run in an MS-DOS window within Windows. Type Help Fdisk at the MS-DOS command prompt to find out more.
  • Page 62 D r i v e U p g r a d e s Configuring the removable media drive Removable-media drives sometimes require configuration, perhaps by altering jumpers on the drive itself, prior to installation. Configuration details vary from drive to drive: a second ATA drive needs to be configured as a slave drive, and a SCSI drive requires that its device ID number be set (the boot SCSI drive is usually drive ‘0’).
  • Page 63 D r i v e U p g r a d e s 8b. If you are fitting a second ATA device, attach the spare connector on the CD-ROM ribbon (signal) cable to the new drive. HINT If your computer does not already have a CD-ROM drive, a suitable ribbon cable should have been supplied with the new drive.
  • Page 64 BIOS SETUP & POST BIOS (pronounced “bye-oss”) stands for ‘basic input/output system’. The BIOS mediates between the computer’s hardware – the processor, memory, and so on – and its software – the operating system and your programs. The BIOS program is kept in permanent, read-only memory or ROM (although if necessary it can be upgraded by an authorised maintainer).
  • Page 65 B I O S S e t u p & P O S T BIOS Setup To start the BIOS Setup utility: Turn on or restart your computer. Wait until the Mitsubishi Electric logo appears on the screen. Press the 2 key. If you have previously defined a Supervisor password, you are prompted for it before BIOS Setup starts.
  • Page 66 B I O S S e t u p & P O S T Changeable fields are enclosed in square brackets. To select an item, use the arrow keys to move the cursor to the field you want. Then use the (+) and (–) keys to select a value for that field.
  • Page 67 PCI/PNP ISA UMB Region Exclusion as required. Multi-boot facility If you restart your computer and press the key while the Mitsubishi Electric logo is on the screen, a diagnostics screen appears, followed by a menu similar to the following: Boot Menu 1. Diskette Drive 2.
  • Page 68 B I O S S e t u p & P O S T In general, you should respond to these errors as follows: Shut down the computer, wait 20 to 30 seconds, and then turn it on again to see if the problem is still reported. Check that all external cables are securely connected.
  • Page 69 B I O S S e t u p & P O S T Keyboard error [nn] or Keyboard controller error There is a problem with the keyboard or (less likely) the standard I/O controller on the motherboard. If POST discovers a stuck key it displays its scan code.
  • Page 70 B I O S S e t u p & P O S T Terminal POST errors and beep codes There are several POST routines that shut down the computer if they fail. If possible, the BIOS displays a two-digit hexadecimal code and/or sounds a sequence of beeps to identify the point at which POST failed.
  • Page 71 TROUBLESHOOTING This chapter offers advice if you suspect a fault with your computer. It is concerned mainly with problems caused by the computer itself; problems more often arise from other sources such as your operating system or application software. It must also be remembered that it can be very easy to leave off or dislodge cables inside the computer when fitting expansion cards, or upgrading the motherboard, or indeed anything that requires temporary removal of the system cover.
  • Page 72 T r o u b l e s h o o t i n g Power-on self-test (POST) Whenever the computer is turned on, the BIOS POST routine tests various hardware components, including memory, and compares the actual configuration of the computer with that recorded in CMOS memory.
  • Page 73 T r o u b l e s h o o t i n g another system diskette, if possible. Make sure that a boot device is correctly specified with the BIOS Setup utility. If the problem persists contact your supplier or authorised maintainer.
  • Page 74 T r o u b l e s h o o t i n g grease and dust from the rollers inside the mouse with a cotton swab moistened with a solvent cleaner. Keyboard If the keyboard response is poor, something may be trapped under the keys.
  • Page 75 T r o u b l e s h o o t i n g diskettes during certain other operations, or until you are about to exit the program. CD-ROM drive If you have problems accessing a CD, check that you have allowed a few seconds for the disk to spin up to full speed, that the disk is the correct way up in the drive (printed side upwards) and that it is a data CD.
