  • Page 21: Using The Computer For The First Time

    Mitsubishi PCs arrive with a pre-installed operating system or ‘Software’. Additional software may be pre-installed at the factory or by your Mitsubishi Electric PC supplier. We strongly recommend that you copy or ‘back-up’ any pre-installed software soon after setting up the system. This is particularly important for systems that are supplied without installation diskettes for the software on the hard disk.

    Windows is sure to display correctly whatever monitor you have. Most modern monitors, including Mitsubishi Electric monitors, can display higher resolutions than standard VGA. You can change the setting to one that more closely matches your own monitor, to get the best performance from it.

  • Page 30: Expansion Cards

    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 31: Configuring The Card

    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 32 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 33 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 34: Installing The Card

    IMPORTANT This system complies with the CE Marking Directive and its strict legal requirements. Use only parts tested and approved by Mitsubishi Electric PC Division. Failure to do so may result in invalidating both the compliance and your warranty. All expansion cards, drives and peripherals must carry the CE mark to ensure continued compliance.

    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.
