W e l c o m e 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.
W e l c o m e Connecting the components Use the following guidance to connect the components together. It is important that you take each step in the order indicated. Before connecting any components, ensure that the AC power supply is switched off or disconnected, and that the system unit, the monitor, and any peripherals are turned off.
GETTING STARTED You should read this chapter even if you do not read any other. It provides important information to help you to use your Apricot server safely and efficiently. Turning on the PC To turn on the computer, simply press the P button.
G e t t i n g S t a r t e d Power saving Use the P button to turn the computer on and change power OWER modes. The colour of the Power Mode indicator shows the current power mode: [red] Off.
G e t t i n g S t a r t e d Manual power saving If you press the P button while the PC is On [green] and OWER running either Windows 95 or Windows for Workgroups, the PC goes into Suspend [yellow] mode.
G e t t i n g S t a r t e d Shutting down the PC To shut down the computer safely, do the following: Wait until all the activity indicators on the front bezel show ‘not busy’. Turn off any attached peripherals, except for the monitor and other peripherals that are designed to be kept on permanently.
G e t t i n g S t a r t e d Using the computer for the first time First time with Windows 95 or Windows NT The first time you turn on your computer you must tell Windows your name (and the name of the company for which you work, if applicable) and agree to the legal terms and conditions of the Windows Licence Agreement.
G e t t i n g S t a r t e d Electronic Fingerprinting Electronic Fingerprinting allows you to ‘brand’ your computer by storing personal information in its permanent memory. If you include your name, address and phone number this will aid the police if your computer is stolen.
Apricot PCs arrive with a pre-installed copy of Windows 95, Windows NT or Windows for Workgroups. 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.
G e t t i n g S t a r t e d Display settings in Windows 95 or Windows NT The monitor setting is changed by using the Settings tab of the ’ Display Properties dialog. See Windows Help for instructions on changing display settings.
REMOVABLE MEDIA DRIVES Diskette drive Your Apricot Server 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 –...

R e m o v a b l e m e d i a d r i v e s DAT tape drive (option) It is recommended to regularly make a backup of the software on the system hard drives. A DAT tape drive is one of the simplest and most convenient methods.
R e m o v a b l e m e d i a d r i v e s Inserting a DAT tape COM PACT Hold the cassette with its metal plate downward and the open tape edge towards the computer. Without using undue force, press the cassette against the drive tape slot.
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.
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.
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.
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).
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.
E x p a n s i o n C a r d s feature cable into the motherboard before you install the card; otherwise, the card may get in the way of the connector. See the Motherboard Features & Upgrades chapter to locate the VESA/AMC connector.
E x p a n s i o n C a r d s 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”.
E x p a n s i o n C a r d s 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: Click the Start button in the taskbar, then Settings, then...
CAUTION Do not alter any jumpers or switch settings other than those identified here, unless told to by your Mitsubishi Electric PC supplier or an authorised maintainer. Otherwise, you may damage the system processor, the motherboard, or both.
M o t h e r b o a r d F e a t u r e s & U p g r a d e s Motherboard jumper settings There are only a few jumpers on the motherboard that you may need to alter.

M o t h e r b o a r d F e a t u r e s & U p g r a d e s BIOS upgrade and recovery (PL11, PL3) These jumpers should not normally be changed except by a service engineer or at the direction of a service engineer.
M o t h e r b o a r d F e a t u r e s & U p g r a d e s Adding more memory You can give your PC more memory by adding or replacing memory modules called “DIMMs”.
M o t h e r b o a r d F e a t u r e s & U p g r a d e s Pushing gently on its top corners, press the DIMM into the socket and make sure the two end clips snap into place. Do not use excessive force.
M o t h e r b o a r d F e a t u r e s & U p g r a d e s Upgrading the processor The ZIF (zero insertion force) “Socket 7” processor socket on the motherboard is designed to accept a variety of processors (see the table earlier in this chapter).
M o t h e r b o a r d F e a t u r e s & U p g r a d e s Lift the processor (with fan-sink) clear of the system unit and place it on an anti-static surface. Hold the processor by its edges and avoid touching any of the metal pins.
M o t h e r b o a r d F e a t u r e s & U p g r a d e s CAUTION If the processor is misaligned it will not go into the socket, and any attempt to force it will damage the processor, the socket or both.

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-inch or 5.25-inch form factor. These may be E-IDE drives, or SCSI drives if you have a SCSI host bus adaptor expansion card.
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.
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.
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.
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.
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’).
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.
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).
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.
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.
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.
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. ♦...
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.
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.
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.
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.
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.
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.
T r o u b l e s h o o t i n g 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.
