OWNER’S HANDBOOK General advice This computer is designed to be used in a normal home or office environment. Here are a few hints for choosing a suitable site: ♦ Place the system unit flat on a sturdy, level surface, free from vibration. ♦ Site the computer away from moisture, direct sunlight, and extremes of heat and cold. Avoid situations in which the surrounding temperature or humidity may change rapidly.
OWNER’S HANDBOOK Backing-up the pre-installed software Apricot PCs arrive with a pre-installed copy of Windows 95. Additional software may be preinstalled 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.
OWNER’S HANDBOOK 2 DISKETTES and CDs Diskette drive Your Apricot PC is fitted with a 1.44 Mbyte diskette drive. This accepts either 1.44 Mbyte (HD) or 720 Kbyte (DD) diskettes. Each diskette has a rigid plastic cover, with a metal shutter that guards the disk surface. Never touch the exposed surface under the shutter – you could deform the disk or leave a fingerprint that might make the diskette difficult to read.
OWNER’S HANDBOOK Ejecting a diskette Write-protecting a diskette ♦ ♦ Wait until the drive’s activity indicator is unlit, then press the EJECT button. If a diskette becomes stuck in the drive, perhaps because its label has peeled back, do not attempt to remove it with tweezers or any similar implement; you risk damaging the drive. Call an authorised maintainer. A diskette can be write-protected by sliding a tab towards the edge of the diskette to expose the small hole beneath it (see illustration).
OWNER’S HANDBOOK CD-ROM drive The CD-ROM drive can retrieve multimedia data from CD-ROM discs and multi-session Photo-CD discs. It can also play normal music CDs (the drive has its own headphone jack and associated volume control). 1 T COMPAC 2 3 4 5 Keep CDs well away from dust and moisture, and avoid touching the surface of the CD. Avoid extremes of temperature and exposure to direct sunlight as these may cause the disc to warp.
OWNER’S HANDBOOK Inserting a compact disc Ejecting a compact disc 1. Press the EJECT button on the front of drive. ♦ 2. Place the CD centrally, printed side up, on the platter. 3. Push the EJECT button again, or gently push the front of the platter to draw it back into the drive. COMPACT 2/4 Diskettes & CDs Ensure that the drive’s activity indicator is not showing ‘busy’, then press the EJECT button.
OWNER’S HANDBOOK 3 MULTIMEDIA Your Apricot MS Series computer has sophisticated on-board video and audio systems and a range of ports and sockets for multimedia applications (some available only on enhanced models).

OWNER’S HANDBOOK Headphones Although this stereo audio socket is intended for headphones it could also be used for output to a personal cassette recorder. When you plug something into this socket, the external speakers are automatically muted. Microphone This mono audio socket provides phantom power for electret-type microphones. Speakers Use this socket to connect the external stereo speakers. These speakers may also be used together with the optional DeepSound sub-woofer.
OWNER’S HANDBOOK MIDI The Musical Instrument Digital Interface is a standard way of connecting musical instruments, synthesisers, computers and other devices. More than merely digitised sound, MIDI encoding provides a complete musical description of a composition and its performance. To connect your computer to other MIDI devices, you’ll need a port adapter to provide separate MIDI In and MIDI Out ports. A MIDI adapter can be obtained from most good music equipment stores.
OWNER’S HANDBOOK 4 EXPANSION CARDS PCI (half length) PCI (half length) Multimedia ports 4 PCI (full length) 1 ISA (full length) 2 ISA (half length) 3 5 6 This diagram shows the layout of the five expansion slots in your PC (as viewed from the rear). Slot 2 is usually occupied by a factory-fitted modem. The sixth “slot” is reserved for multimedia ports. Important This system complies with the CE Marking Directive and its strict legal requirements.
OWNER’S HANDBOOK 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. Most modern PCI cards employ a feature called “Plug and Play” (PnP). This allows Windows 95 – and other PnP-aware operating systems – to configure the card automatically the first time you turn on the computer after installing the card. However, many ISA cards (and some PCI cards) require manual configuration.
OWNER’S HANDBOOK 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. Your PC has interrupt levels numbered IRQ0 to IRQ15, many of which are needed for components on the computer’s motherboard. There are two ways round this. ♦ ♦ Many motherboard components are Plug and Play (PnP) devices.
OWNER’S HANDBOOK Base memory address More about memory addresses 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). 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).
OWNER’S HANDBOOK 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. Always shut down the computer and unplug all power cords before removing the top cover. The only tool required is a small cross-head screwdriver. 1. Turn off the computer and unplug all power cords. 2. Take suitable anti-static precautions and remove the system unit cover.
OWNER’S HANDBOOK Caution Be careful how you use the AMC connector. Some pins carry +5 V power which could damage the expansion card if it is incorrectly attached. 4/6 5. If the card you are installing is configured by the means of jumpers or switches, check that it is correctly configured before proceeding. 6.
OWNER’S HANDBOOK Reserving ISA legacy resources If the computer does not automatically detect the new expansion card the first time you turn it on, start the BIOS Setup utility, go to the Advanced menu and change the Reset Configuration Data item to “Yes”. If you have just installed an ISA card, you may also want to reserve or exclude the legacy resources (that is, the interrupts and UMB regions) used by the card.
OWNER’S HANDBOOK Telling Windows about the new hardware Windows 95 and Windows NT 4.x (or later) should automatically detect and configure cards that support “Plug and Play”. In other cases you may have to tell Windows that you have installed new hardware, as follows: 4/8 1. Click the Start button in the taskbar, then Settings, then Control Panel. 2. Double-click on Add New Hardware. 3. Follow the instructions in the Add New Hardware Wizard.
OWNER’S HANDBOOK 5 MOTHERBOARD FEATURES AND UPGRADES This chapter describes the features of the computer motherboard and gives step-by-step instructions for adding more system or video memory, upgrading the processor, and replacing the configuration battery. Details of all relevant motherboard connectors and jumper settings are included. The Welcome chapter tells you how to remove the system unit cover.

OWNER’S HANDBOOK Motherboard jumper settings There are only a few jumpers on the motherboard that you may need to alter. All others are set at the factory and should not be changed. On the motherboard, pin 1 of each jumper block is indicated by a small triangular marking. Do not change jumper settings unnecessarily Do not alter any jumpers or switch settings other than those identified in this chapter, unless told to by your Mitsubishi Electric PC supplier or an authorised maintainer.
OWNER’S HANDBOOK On-board video disabling (J50) If you install a video adapter expansion card, the computer should automatically detect this and disable the on-board video adapter. If for some reason this does not happen, and you experience problems with a newly-fitted card, you can manually disable the onboard video adapter by moving the jumper in block J50 to pins 2-3. Audio disabling (J80) The on-board audio codec can be disabled by moving the jumpers on jumper block J80 to pins 2-3.

OWNER’S HANDBOOK Base Input/Output (I/O) port addresses The following table lists addresses used by components on the motherboard. Any ports between 100h and 3FFh that are not listed may be used by an expansion card.
OWNER’S HANDBOOK Adding more memory You can give your PC more memory by adding or replacing memory modules called “DIMMs”. The motherboard’s two DIMM sockets accept DIMMs of up to 128 Mbytes in any combination (giving a maximum memory capacity of 256 Mbytes). Technical note The DIMMs you use must have the following specification: gold contacts, 3.3V, 64-bit, unbuffered, SDRAM-type with Serial Presence Detect (SPD) and a CAS latency of 2 at 66 MHz.
OWNER’S HANDBOOK Removing a DIMM If you need to start by removing a DIMM, follow the diagrams on the left, depending on what type of socket you have. If you have this type of socket, press the tabs on both of the socket’s end clips at the same time. This releases the DIMM and lifts it partly out of the socket. Hold the DIMM by its ends and avoid touching the metal contacts. Place the DIMM in suitable antistatic packaging.
OWNER’S HANDBOOK Inserting a DIMM When you take the DIMM out of its anti-static packaging, hold it by its ends and avoid touching the metal contacts. Follow the diagrams on the right to insert the DIMM, depending on what type of socket you have. In either case, there are asymmetrical indents along the connector edge that prevent the DIMM being fitted into the socket the wrong way round. If you have this type of socket, the DIMM is inserted vertically and held in place by the clips at each end.
OWNER’S HANDBOOK Adding more video memory Video memory is memory reserved for use by the onboard video controller. More video memory can provide more colours or higher resolutions to an extent determined by the capabilities of your monitor. 5. Insert the SODIMM into the socket as shown below. 6. Replace any expansion cards you removed earlier and refit the system unit cover.
OWNER’S HANDBOOK Upgrading the processor The ZIF (zero insertion force) “Socket 7” processor socket on the motherboard is designed to accept a variety of Pentium/MMX processors. You may wish to upgrade your processor by replacing it with one of higher performance. 1. Turn off the computer and unplug all power cords. 2. Take suitable anti-static precautions and remove the system unit cover.
OWNER’S HANDBOOK 5. Unplug the power cable of the processor’s fansink from the motherboard. Note where the cable plugs in because you will need to re-attach it later. 6. Press down on the fan-sink’s retention clip to release it (A) then unhook the clip from the other side of the ZIF socket (B). 7. Release the lever (C) from the side of the ZIF socket and raise it to the upright position, at right-angles to the motherboard.
OWNER’S HANDBOOK Warning When you remove the fan-sink there will be a residual deposit of thermal bonding compound on the bottom of the fan-sink and the top of the processor. This compound can cause skin irritation and stain clothing. Avoid prolonged or repeated contact with skin. Wash your hands thoroughly with soap and water after handling. Avoid contact with eyes and inhalation of fumes. Do not ingest. A B 10. Ensure that the securing lever on the ZIF socket is still in the upright position. 11.
OWNER’S HANDBOOK 15. Reconnect the fan-sink’s power cable to the motherboard. Caution If the fan-sink power cable is not reconnected properly, the processor may run slowly or not at all, and there is a risk that it may overheat and be permanently damaged. 16. Adjust the processor bus speed selection jumpers in block J10 as described at the start of this chapter. D When you have finished, replace any expansion cards you needed to remove, then refit the system unit cover. E 13.
OWNER’S HANDBOOK Replacing the configuration battery 3 The computer keeps a record of its current hardware configuration in a CMOS memory chip which is sustained by a small battery. This battery has a life of up to 5 years. If you find that you have to reconfigure the computer every time you turn it on, the battery is probably failing and needs to be replaced. To replace the battery 1. Turn off the computer and unplug all power cords. 2.
OWNER’S HANDBOOK 5. Check that the replacement battery looks the same as the battery you have removed. 6. Taking care not to touch the top or bottom surface of the battery, pick up the replacement with the positive (+) terminal upwards. Press the battery into the holder using a non-conductive implement. 7. Replace any expansion cards you removed earlier and refit the system unit cover. 8. Dispose of the discharged battery in accordance with the battery manufacturer’s instructions.
OWNER’S HANDBOOK 6 HARD DISK UPGRADES This chapter describes how to add a second hard disk to your computer. 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. 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.
OWNER’S HANDBOOK Configuring the drive Your computer can accommodate two E-IDE hard disk drives, known as the master and slave drives. The first drive, which contains the operating system, is always configured as the master. The second drive must be configured as the slave. Hard disk drives are normally configured as master or slave by using jumpers on the drive itself. Configuration details vary from drive to drive. Most drives are supplied with documentation describing how to configure the drive.
OWNER’S HANDBOOK Installing the drive B B A 1. Turn off the computer and unplug all power cords. 2. If there is a diskette in the diskette drive, remove it. 3. Take suitable anti-static precautions and remove the system unit cover. For more information see “Anti-static precautions” in the Safety & Regulatory Notices at the start of this manual. 4. Disconnect the power and signal (ribbon) cables from the rear of the diskette drive. Take careful note of how they are fitted. 5.
OWNER’S HANDBOOK 7. Loosen the four screws labelled (B) in the diagram. Slide the drive assembly towards the rear of the system and lift it out. 8. Fit the new (slave) hard drive into the drive assembly using the special screws provided (see below). Try not to touch any drive’s electronics. T COMPAC B A 9. Put the drive assembly back into the system unit and tighten the (B) screws to secure it to the chassis. 10. Re-attach the HDD signal cable to the master and slave drives.
OWNER’S HANDBOOK Partitioning and formatting the drive If the computer does not automatically detect the new drive the first time you turn it on, start the BIOS Setup utility, go to the Advanced menu and change the Reset Configuration Data item to “Yes”, then restart the computer. The new drive will initially be blank. Before you can use the drive, you must partition and format it.
OWNER’S HANDBOOK 7 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). BIOS Setup is a helpful utility that forms part of the BIOS program.
OWNER’S HANDBOOK BIOS Setup 7/2 Starting BIOS Setup If BIOS Setup starts on its own To start the BIOS Setup utility: BIOS Setup might start on its own for three reasons: 1. Turn on or restart your computer. ♦ 2. Wait until the Mitsubishi Electric logo appears on the screen. The power-on self-test (POST) detects a configuration error or fault. This may be signalled by one or more POST error messages.
OWNER’S HANDBOOK Press To Control keys F1 View a general help topic. Press ESC to close the help window. Exit the current menu. Select a different menu. Select fields on the current menu. Select the next value for the current field. Select the previous value for the current field. Execute a command or enter a submenu. Move the cursor to the top or bottom of the current menu. Move the cursor to the next or previous page of the current menu. Restore the default settings for all menus.
OWNER’S HANDBOOK Getting help in BIOS Setup Reserving ISA legacy resources You can at any time get general help about the control keys by pressing the F1 key. To reserve interrupts and upper memory block (UMB) regions for ISA expansion cards, go to the Advanced menu, select PCI Configuration, then select PCI/PNP ISA IRQ Resource Exclusion or PCI/PNP ISA UMB Region Exclusion as required. The help window on the right-hand side of each menu displays help text for the currently-selected field.
OWNER’S HANDBOOK Diskette drive A error Drive A: is present but fails the POST diskette tests. Check that the drive is defined correctly in BIOS Setup. If necessary, open the system unit and check that the drive’s signal (ribbon) cable is connected. System/Extended/Shadow RAM failed at offset: xxxx Failing bits: yyyy System, extended or shadow memory is not working, or not configured properly, at offset xxxx. The hexadecimal number yyyy is a map of the bits at the address which failed the memory test.
OWNER’S HANDBOOK Previous boot incomplete - default configuration used The previous POST did not complete successfully. POST loads default values and offers to start BIOS Setup. If the failure was caused by incorrect values and they are not corrected, the next boot will likely fail too. System CMOS checksum bad - run Setup System CMOS has been corrupted or modified incorrectly, perhaps by an application program that changes data stored in CMOS.
OWNER’S HANDBOOK Code Beeps Test which failed Terminal POST errors and beep codes 16 1-2-2-3 BIOS ROM checksum 20 1-3-1-1 DRAM refresh. 22 1-3-1-3 8742 keyboard controller 2C xxxx 1-3-4-1 RAM failure on address line xxxx. 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. The most usual errors are listed in the table on the left.
OWNER’S HANDBOOK 8 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.
OWNER’S HANDBOOK Problems when starting If you suspect a blown fuse Power-on self-test (POST) In the United Kingdom, and some other countries, AC plugs contain fuses. If the fuse in the system’s unit AC plug blows when you turn on the computer, this may be caused by an AC power surge, but is more often a symptom of problems with the computer or its peripherals.
OWNER’S HANDBOOK Diskette read failure The diskette is either not formatted or defective. Either remove it, or replace it with a system diskette, and press F1. No boot sector on fixed disk The hard disk has no active, bootable partition or is not formatted. If you are still using the original master hard disk drive supplied with your computer, this is a serious problem requiring the attention of a service engineer.
OWNER’S HANDBOOK Common problems If you encounter a problem with the computer the following sections suggest checks to make before you alert your supplier, authorised maintainer or support organisation. The checks listed cover the causes of common problems. Monitor Connections If you have fitted a new video controller expansion card and subsequently encounter problems try disabling the on-board video controller by removing a jumper from the motherboard.
OWNER’S HANDBOOK Keyboard Expansion cards If the keyboard response is poor, something may be trapped under the keys. Turn the keyboard upside down and shake it; do not probe between the keys as this may cause further damage.
OWNER’S HANDBOOK Diskette drive Overheating If you have problems accessing a diskette, check that it is inserted correctly, that it has been correctly formatted, that it is not write-protected, and that the diskette drive controller is enabled. Some application software also may not allow you to read or write to diskettes during certain other operations, or until you are about to exit the program.
