Welcome 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.
Welcome Connecting the components Use the following guidance to connect the components together. It is important that you take each step in the order indicated. 1. 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. 2. Connect the components’ signal cables to their respective ports on the system unit: keyboard, mouse, monitor, audio (where appropriate) and any other peripherals.
Welcome place or ‘pre-installed’ on the hard disk, so that the operating system is ready for you when you turn on the computer. NOTE If a diskette is in the diskette drive when the computer is turned on, the computer will attempt to boot using that diskette. This will succeed only if the diskette is a ‘system diskette’; that is, one bearing at least the rudiments of an operating system. Shutting down the PC To shut down the computer safely, do the following: 1.
Welcome Emergency shut down In exceptional circumstances, you can put your PC into Off [red] mode without shutting down the operating system. To do this, press and hold down the POWER button for at least four seconds. This should be only a last resort, as some operating systems create temporary files as part of their procedure and these are deleted during a normal shutdown. They would remain on your hard drive in an emergency shut down and will require manual deletion.
Welcome ♦ The Microsoft Create System Disks utility or the Disk Maker utility (Windows NT) allows you to create installation diskettes from disk images pre-installed on the hard disk. ♦ To back up other pre-installed software (and your own files) use the Backup tool in Windows. You could also use other software backup utilities supplied with optional hardware you may have chosen, such as a DAT tape drive.
Welcome If your hard disk is larger than 2 gigabytes If you have Windows NT, the first 2 Gbytes are formatted (using FAT) as a primary partition. The rest of the disk is untouched. You can repartition and reformat the disk using the Disk Administrator tool in the Administrative Tools (Common) folder. CAUTION Take great care when creating and formatting new partitions not to damage, delete or format your existing ‘boot’ partition.
2 REMOVABLE MEDIA DRIVES Diskette drive Your FT1200 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 – you could deform the disk or leave a fingerprint that might make the diskette difficult to read. Inserting a diskette 1.
Removable media drives Ejecting 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.
Removable media drives 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). Do not attempt to move the computer while a CD is in the drive, especially if the CD is being played at the time.
Removable media drives Inserting 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 Ejecting a compact disc ♦ Ensure that the drive’s activity indicator is not showing ‘busy’, then press the EJECT button.
Removable media drives 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. The drive can be obtained from your supplier as an upgrade kit. A brief installation guide is give in the chapter, ‘Drive upgrades’. Operating system software can be easily reinstalled from the master software disks or CD-ROMs, but created data from a multitude of server users can not be easily replaced.
Removable media drives Inserting a DAT tape COMPACT 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. The dust cover will swing open allowing the tape cassette to enter. Push firmly home. With some models of drive, the cassette does not enter the drive completely. The ‘Cassette engaged’ green light should come on.
3 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.
Expansion Cards 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.
Expansion Cards 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. ♦ You can disable certain motherboard components either by means of the BIOS Setup utility or else by changing jumper settings on the motherboard.
Expansion Cards 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). In order that this memory can be recognised by the system processor, it must be mapped somewhere within the computer’s own address space. By setting the “base memory address” you specify where the card’s memory begins within the address space.
Expansion Cards 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. 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.
Expansion Cards 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. CAUTION Be careful how you use this connector. Some pins carry +5 V power which could damage the expansion card if it is incorrectly attached. 4-2 7. Position the expansion card alongside the slot in which you wish to install it.
Expansion Cards 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 need to reserve or exclude the legacy resources (that is, the interrupts and UMB regions) used by the card.
4 SCSI DRIVES This chapter describes installation of and support for SCSI devices, how to configure them and how to use the SCSISelect utility. SCSI Device Support The motherboard has an Adaptec AIC-7895 dual-channel SCSI controller chip integrated as a PCI bus master. The controller supports data path widths of 8-bit (narrow SCSI) at a data transfer rate of up to 20 MB/sec and 16-bit (wide SCSI) at a data transfer rate of up to 40 MB/sec.

SCSI drives Installing in the forward drive bay To install a second hard disk drive in the forward drive bay: 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 all the system panels. 4. Carefully remove the plastic bezel blanking insert from the lowest front drive slot by pushing it out from the rear with a blunt instrument (for example, the end of a rubber-tipped pencil).
SCSI drives Installing in the rear drive bay The rear drive bay has a cooling fan for the processors mounted on the rear. This has a power connection to the motherboard. 1. Turn off the computer and unplug all power cords. 2. Take suitable anti-static precautions and remove the system side panel. 3. If the rear drive bay already contains a SCSI drive, unplug the SCSI ribbon (signal) cable and power cable from that drive. 4.
SCSI drives Partitioning and formatting the drive The new drive will initially be blank. Before you can use the drive, you must partition and format it. Although drives can be formatted using Windows, it is recommended to use the SCSISelect utility described later in this chapter. CAUTION Take great care when creating and formatting new partitions not to damage, delete or format your existing ‘boot’ partition.
SCSI drives 4. Pull out the metal blanking plate from the front of the internal drive bay metalwork. 5. Carefully slide the new drive into the bay from the front and secure it on both sides using the special screws provided with the drive. 6. Attach a spare power cable to the drive (it does not matter greatly which of the available power cables you choose). 7.
SCSI drives Using the SCSISelect Utility The SCSISelect Utility enables you to: ♦ Modify the SCSI controller's configuration (including termination) ♦ Change SCSI device settings that conflict with other device settings ♦ Perform a low-level format on SCSI devices connected to the motherboard To enter the utility To enter the SCSISelect Utility, boot the computer and when the following message appears: press Press for SCSISelect(TM) Utility! The table below provides an overview
SCSI drives SCSI Disk Utilities When selected, this brings up the SCSI Disk Utilities Menu. Configuration Menu NOTE In the utility, an asterisk (*) indicates the default setting for a field. Host Adapter SCSI ID Specifies the SCSI ID of the host adapter. The options are ID 0–15. The default is ID 7. SCSI Parity Checking Enables or disables parity checking. When enabled, the host adapter checks parity when reading from the SCSI bus to verify the correct transmission of data from the SCSI devices.
SCSI drives Boot Device Configuration Boot Channel Specifies the SCSI channel from which the computer should boot. The options are: ♦ A First (default) ♦ B First Boot SCSI ID Specifies the SCSI ID of the device from which you wish to boot. The options are ID 0–15. The default is ID 0. The SCSI ID selected here must correspond to the ID configured on the boot device.
SCSI drives Enable Disconnection Sets whether the motherboard allows SCSI devices to disconnect from the SCSI bus. Enabling disconnection allows the motherboard to perform other operations on the SCSI bus while the SCSI device is temporarily disconnected. If two or more SCSI devices are connected to the host adapter, select Yes. The options are: ♦ Yes (default) ♦ No Initiate Wide Negotiation Specifies whether the motherboard attempts 16-bit instead of 8-bit data transfer.
SCSI drives Include in BIOS Scan Specifies whether a device is included in the SCSI BIOS scan at boot. Selecting No removes the device from the scan. The device will not be assigned a SCSI ID. This option can be useful when changing boot order or if a device has not been responding properly. The options are: ♦ Yes (default) ♦ No Advanced Configuration Options Plug and Play SCAM Support Enables or disables support for SCAM Level 1 and Level 2 SCSI devices.
SCSI drives Use Extended BIOS Translation only with MS-DOS 5.0 or higher. You do not need to enable this option if you are using another operating system such as NetWare, Windows NT, or UNIX. When you partition a disk larger than 1 GB, use the MS-DOS fdisk utility as you normally would. Because the cylinder size increases to 8 MB under extended translation, the partition size you choose must be a multiple of 8 MB.
SCSI drives ♦ All Disks (All removable-media drives supported by the BIOS are treated as hard disk drives) ♦ Disabled (No removable-media drives are treated as hard disk drives. In this situation, software drivers are needed because the drives are not controlled by the BIOS) Display Message During BIOS Initialization NOTE This option does not affect your ability to access the SCSISelect Utility. It only toggles the prompt.
SCSI drives Using the SCSI Disk Utilities To enter the SCSI Disk Utilities, select the SCSI Disk Utilities option from the SCSISelect menu. When you select this option, SCSISelect scans the SCSI bus (to determine the devices installed) and displays a list of all SCSI IDs and the devices assigned to each ID. When you select a specific ID and device, a small menu appears, displaying two options: Format Disk and Verify Disk Media. Format Disk CAUTION A low-level format destroys all data on the drive.

6 BIOS SETUP AND MENUS The motherboard’s system BIOS is contained in a flash memory device on the motherboard. The BIOS provides the power-on self test (POST), the BIOS Setup program, the PCI and IDE autoconfiguration utilities, and the SCSISelect Utility. The BIOS is always shadowed.

7 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.
Troubleshooting 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. If POST detects a hardware fault, one or more POST error codes or messages may be displayed. See the BIOS Setup & POST chapter for more information and advice.
Troubleshooting 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. 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.
Troubleshooting 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. Turn the keyboard upside down and shake it; do not probe between the keys as this may cause further damage. If you spill something on the keyboard and it stops working: ♦ If the liquid is viscous, unplug the keyboard and call your supplier or an authorised maintainer.
Troubleshooting 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. Remember that with a conventional CD-ROM drive you cannot write to a CD.
EQUIPMENT LOG Use this equipment log to record information about your PC. You may wish to cut it out and keep it in a safe place. Manufacturer’s data You should record the model codes and serial numbers of the system components. You can update this with information about any expansion cards fitted.
