USING YOUR COMPUTER
This chapter provides useful information on the correct operation of
the drives fitted to your computer.
Using the 3.5" diskette drive
The floppy disk drive is usually configured in the system BIOS as
drive A:, with a capacity of 1.44 Mbytes.
Inserting a diskette
A diskette is inserted into the diskette drive slot shutter-foremost,
and with its label side facing up. Some diskettes have a small arrow
on the face of the diskette; this must point towards the drive when
you insert the diskette.
COMPACT
Push the diskette all the way in until it engages with the drive
mechanism. When the drive’s eject button pops out, the diskette is
fully engaged.
FT1200 OWNER’S HANDBOOK
2/1
Using your computer
Removing a diskette
Before attempting to remove a diskette, make sure that the drive is
not currently in use (the diskette activity indicator, opposite the
drive’s eject button must be unlit). Press the eject button on the
drive. The drive mechanism disengages and the diskette is ejected
half-way out of the drive.
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.
The BIOS Setup utility can be used to bar access to the diskette
drive. See ‘System BIOS and Setup’ for further details.
Care of floppy diskettes
Keep diskettes well away from dust, moisture, magnetic objects, and
equipment that generates magnetic fields (such as telephones or
monitors). Also, avoid extremes of temperature and exposure to
direct sunlight.
Make sure that diskette labels are secure before using the diskette
and do not leave diskettes in the drive when the computer is
switched off or not in use.
Do not open the metal shutter or touch the disk surface,
fingerprints can easily destroy the delicate surface. Store diskettes in
a safe place, or locked away in secure storage container.
Using the 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 audio CDs.
Warning
The laser beam inside the CD-ROM drive is harmful to the eyes. Do
not attempt to disassemble the CD-ROM drive. If a fault should occur
it is advisable to contact an authorised maintainer.

Care of CDs
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 disk to warp.
Always store CDs in their original cases wherever possible.
Replacement cases are readily available in the larger record stores.
CD storage racks are useful as you will find the majority of new
software is now supplied in CD format.

Using your computer
Optional DAT tape drive
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.
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. The common backup
method is to use two or three tapes in rotation, either weekly, daily
or even twice daily for large organisations with complex networking.

Removing a DAT tape
Wait until the amber drive active light goes out and all activity has
ceased, then press the Eject button. The cassette will move outwards
and is easily lifted clear.
Care of DAT cassettes
Always store cassettes in their original dust tight cases. Keep them
away from dust, moisture, magnetic objects, and equipment that
generates magnetic fields (such as telephones or monitors). Avoid
extremes of temperature and exposure to direct sunlight.
FT1200 OWNER’S HANDBOOK
2/7
Using your computer
Make sure that labels are secure before use and do not leave cassettes
in the drive when the computer is switched off or not in use.
Cleaning your drives
Cleaning a floppy drive
Do not insert cotton buds or other implements into the drive door.
If you think the drive needs cleaning, obtain a specialist cleaning kit
from a reputable supplier. It will come with instructions for its
correct use. It looks like a floppy disk, but has a special head
cleaning surface inside which removes dust and fluff from the
reading heads and the mechanism. They should be used only once
and then discarded.
Cleaning the CD-ROM
It is recommended that you occasionally use a specialist CD
cleaning disk to clean the lens in the drive as it may become dusty
and fail to operate. Similar rules apply as for the floppy drive.
Cleaning the DAT drive
The tape transport mechanism and the read/write head should be
inspected periodically for dust and debris. Full cleaning is
recommended after every 12 hours of use. As with floppy and CD
drives, a special cleaning cartridge is available from reputable
suppliers, which will be supplied with full instructions for use.

guaranteed. Any damage caused by fitting non approved drives will not
be covered by the system warranty.
SCSI hard drives
If you do not feel confident about the procedure you could have
your supplier or service organisation complete it for you.
Your computer can support several SCSI devices, hard drives, tape
drives etc. It is possible to install as many devices as there are spaces
for. However, if a tape drive is fitted below the CD-ROM drive,
only one additional hard drive can be fitted within the main drive
bay, in the space above the existing drive.
FT1200 OWNER’S HANDBOOK
3/1
Adding new drives
Second hard drive
1.
Turn off the computer and unplug all power cords. Take
suitable anti-static precautions and remove the system side
panels. Detailed instructions for this are given in chapter 1.
Caution
If you are unfamiliar with the recommended anti-static precautions,
refer to the antistatic section at the rear of this handbook.
2.
Carefully remove the front bezel blanking insert by pushing it
off from the rear with a blunt point. A hole for this is provided
inside the system, alongside the main drive bay.
3.
Pull out the metal blanking plate on the front of the internal
drive bay metalwork.
◊ Additional SCSI drives, of whatever type, all need to be set
to have a different ‘ID’ number. The first or bootable drive
is usually set to device ‘0’. The information supplied with
the drive should give details on the setting of ‘ID’ jumpers.
Caution
If you are using a RAID (Redundant Array of Independent Disks)
configuration. Altering the settings on any of your existing drives, risks
losing all the data on all of your hard disk drives.
3.
Remove any fitted drive mounting brackets from the drive bay
and put to one side if not required for the new drive.
4.
Slide the new hard drive, (with the drive mounting brackets
fitted if required) into the drive bay from the front and secure
it with screws into the space immediately above the existing
hard drive.
◊ Take great care not to touch the exposed circuit board.
Note
A new drive will usually require mounting brackets to fit into the main
drive bay, but the drive caddy is the correct size for half height drives.
5.

Connect a power cable from one of the available unused ones.
FT1200 OWNER’S HANDBOOK
Adding new drives
6.
Connect the hard disk ribbon cable to the new drive. The
ribbon is striped to indicate pin 1, which usually goes to the
end nearest the power connector.
7.
Refit the system side panels, metal plate and bezel insert.
It will now be necessary to run the disk preparation utilities to
partition and format the disk to your requirements. Your software
guide or the operating system HELP should provide information on
this topic.
Further drives will have to be installed in the auxiliary hard drive
bay above the power supply, which can accommodate two drives.
This is easily removed and drives should be fitted into it with their
connectors facing the front of the system.
Fitting front drives/accessories
There is sometimes a requirement to fit extra components into the
system, such as the DAT drive (described in the previous chapter),
extra CD-ROM drives etc.
The drive or accessory you are about to install should have fixing
and installation instructions with it, making it a fairly simple task. If
you do not feel confident about the procedure you could have your
supplier or service organisation complete it for you.
1.
Turn off the computer and unplug all power cords. Take
suitable anti-static precautions and remove both of the system
side panels. It may also be necessary to remove the top panel.
Detailed instructions for this are given in chapter 1.
Caution
If you are unfamiliar with the recommended anti-static precautions,
refer to the antistatic section at the rear of this handbook.
2.
Carefully remove the front bezel blanking insert by pushing it
off from the rear with a blunt point. A hole for this is provided
inside the system, alongside the main drive bay.
3.
Pull out the blanking plate on the front of the internal drive
bay metalwork.
FT1200 OWNER’S HANDBOOK
3/3

4.
Check before sliding the device into the system, that any
device jumpers have been correctly set, for example, SCSI ‘ID’.
5.
Carefully slide the new device into the bay from the front and
secure it with screws on both sides. Make sure that the front of
the device is aligned as close as possible to the front bezel.
6.
Fit any control card into an appropriate expansion slot.
◊ Information is given in the following chapter about the
correct method of installing cards.
7.
Connect a suitable power cable from one of the available
unused ones.
8.
Follow any additional instructions provided as regards to signal
cables etc.
◊ A DAT drive may require a long ribbon cable to reach the
controller card fitted into a riser board slot.
9.
After checking that no other cables have become dislodged or
trapped, refit the system panels.
10. Follow any additional installation instructions as given in the
units manuals, such as software or configuration requirements.

EXPANSION CARDS
If, having read the following installation instructions, you do not
feel confident about installing expansion cards yourself you may
wish your supplier or service organisation to fit the card for you.
The only tool required is a small cross-head screwdriver.
Warning
Never carry out any work on the equipment with power applied. Always
switch off at the supply and remove the power lead from the equipment
before starting work.
Configuring the card
The documentation accompanying the card should tell you what is
required. Remember to check any diskettes supplied with the card
for README or other help files, before you start. If you are in any
doubt consult the supplier or manufacturer.
If manual configuration is required, usually with ‘Industry Standard
Architecture’ (ISA) cards, then you will probably need to specify at
least two of the following:
♦
Interrupt request level (IRQ)
♦
Direct memory access (DMA) channel
♦
Base input/output (I/O) port address
♦
Base memory address
The important thing to understand is that the settings used by the
card must be different from the settings used by the other hardware
in the computer, whether another card or a component on the
motherboard, the settings must not conflict.
Some settings are done by jumpers and/or switches on the card and
are best done before installation, others are configured by running
installation software after installation. Some cards use a mixture of
both methods. Cards often come with pre-configured or default
settings. It is best to rely on these settings as much as possible, and
change them only if they conflict with other devices.
FT1200 OWNER’S HANDBOOK

Expansion cards
Caution
This system complies with the CE marking directive and its strict legal
requirements. Use only Apricot tested and approved parts. Failure to do
so may result in invalidating both the compliance and your warranty.
All expansion cards or upgrade components must carry CE marking.
ISA Interrupt request level (IRQ)
The interrupt request level or IRQ is the line over which the
expansion card sends a signal to get the attention of, or interrupt,
the processor. Many of these are reserved for components on the
computer’s motherboard. Some of these interrupts are fixed, others
can be re-assigned, or freed by disabling the component with BIOS
Setup, as shown in the following table:

Expansion cards
Do not disable either one unless you have no intention of using the
affected port. Similarly, if you have no intention of using the
parallel port, you can disable it with the BIOS Setup utility,
completely freeing IRQ7 for use by an expansion card.
Direct memory access (DMA) channel
Some hardware devices can use a DMA channel to access system
memory without directly burdening the processor. Computers have
DMA channels numbered DMA0 to DMA7. The following table
gives details of which ones may be available:

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
4/4
FT1200 OWNER’S HANDBOOK
Expansion cards
where the card’s memory begins within the address space. Typically,
an expansion card’s memory must be mapped onto the addresses
between C8000h and DFFFF in upper memory. With most
modern expansion cards this is fully automatic.
The card’s documentation should list its possible base memory
addresses. You will also need to know how much memory the card
has, so that you can leave the right gap between this card’s base
address and the next.
Cards often come with pre-configured or default settings. It is best
to rely on these settings as much as possible, and change them only
if they conflict with other devices.
Installing a card
Installing expansion cards can be one of the most difficult
operations you may ever perform within your computer. If you are
in any doubt, or come into difficulties you are unable to resolve,
contact the supplier of the expansion card or ask your Apricot dealer
for advice or assistance.
1.
Turn off the computer and unplug all power cords. Take
suitable anti-static precautions and remove the system side and
top panels, detailed information is given in chapter 1.
Caution
If you are unfamiliar with the recommended anti-static precautions,
refer to the antistatic section at the rear of this handbook.
2.
At the rear of the system unit are metal blanking plates, one for
each expansion card slot. To ensure the front edge of a full
length card is securely supported you will find card guides on
the front of the machine, on the back of the fan assembly.
3.
First decide in which of the available slots you wish to install
the card. Not all slots will accept the same type of card.
4.
Remove the blanking plate of the chosen slot by removing its
securing screw, then sliding the blanking plate out of its slot.
Keep the screw, it will be needed later to secure the card.

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 and connectors inside the computer when fitting
expansion cards, or upgrading the motherboard, or indeed anything
that may require temporary removal of the system cover.
If in doubt
Turn off the computer and unplug the power cord before consulting
your supplier or maintenance provider. Make a note of any of the
symptoms, error codes, display messages etc., before calling.
Problems when starting
If you suspect a blown fuse
In the United Kingdom, and some other countries, AC plugs
contain fuses. Your Apricot computer is initially supplied and fitted
with the correct supply cable and fuse for operation in the country
in which it is sold. 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. Follow these steps:
1.
Turn off the computer and unplug all power cords.
2.
Unplug all peripherals.
3.
Try to discover the cause of the fault. If none is apparent,
replace the blown fuse with one of the same rating, reconnect
the system unit power cord and try to turn it on again.
4.
If the replacement fuse blows, call your supplier or
maintenance provider.
5.
If the replacement fuse does not blow, reconnect one
peripheral at a time and switch it on. Repeat this step for each
peripheral in turn.

Troubleshooting
Power-on self-test (POST)
Whenever the computer is turned on, the power-on self-test
(POST) routine tests various hardware components, including
memory, and compares the actual configuration of the computer
with that recorded in configuration (CMOS) memory. During this
time, BIOS sign-on and POST messages are displayed.
A configuration discrepancy could arise if you have just installed or
removed a hardware option (for example, if you have added or
replaced memory). In this case you may be diverted directly into the
BIOS Setup utility.
If POST detects a hardware fault, one or more POST error codes
and messages are displayed. A full list of these is given at the end of
‘System BIOS and Setup’. You may also be prompted to “Press the
F1 key to continue” or “Press any key when ready”.
Your first action should be to turn off the computer, wait 20 to 30
seconds, and then turn it on again to see if the error is transitory or
persistent. Persistent POST errors may indicate a fault in the system.
♦
Check that all external cables are securely connected.
♦
Try running the BIOS Setup utility to reconfigure the system.
♦
Open up the system unit and check that all internal signal and
power cables are securely connected.
If the problem persists, call your supplier or authorised maintainer.
Failure to boot
On completion of POST, the computer attempts to boot from a
system diskette or bootable hard disk partition. The table below lists
some of the messages that might appear during the boot sequence.
Boot failure message
Explanation
Non-system disk or disk error
The diskette drive contains a non-system diskette. Replace it
with a system diskette and press F1.
Diskette read failure
The diskette is either not formatted or defective. Replace it
with a system diskette and press F1.

formatted. Insert a system diskette, press F1, and format the
hard disk as described in your operating system manuals.
Fixed disk read failure
The hard disk may be defective. Press F1 to retry. Make sure
the drive is correctly specified in the BIOS setup utility. If the
problem persists, insert a system diskette, press F1, backup the
data held on the defective hard disk and try reformatting it.
No boot device available
This may indicate a fault in the diskette or hard disk drive, or
perhaps a damaged system diskette. Press F1 to retry, using
another system diskette, if possible. Make sure that the Startup
Devices option is correctly specified with the BIOS Setup
utility. If the problem persists contact your supplier or
authorised maintainer.
Troubleshooting checklist
If you encounter a problem with the computer the following
sections suggest checks to make before you alert your dealer,
authorised maintainer or support organisation. The checks listed
cover the causes of common problems.
Connections
Check that all power and signal cables are securely connected to the
correct port on the computer.
The keyboard and mouse are particularly easy to connect into the
wrong port. Although the connectors are identical, the keyboard
will not work if plugged into the mouse port, and vice versa.
The two serial ports also appear identical. If you have a problem
make sure that the cable is connected to the port you are trying to use.
Power
Check that the AC power supply is switched on, and that the fuse
in the AC plug (if any) has not blown. If the system still does not
seem to be getting power, obtain another power cord from your
supplier.
FT1200 OWNER’S HANDBOOK

Troubleshooting
Monitor
If there is no display check that the monitor is turned on, and the
brightness and contrast controls are not too low.
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. See the
chapter ‘System motherboard’ for more information.
Expansion cards
If an expansion card does not work, check that all internal cables are
securely connected, that the card is configured correctly, that its use
of system resources does not conflict another card or motherboard
component, and that legacy resources (if it is an ISA card) are
properly declared in the BIOS setup utility. Check also that the
software which drives or uses the card is correctly configured. Check
in the chapter, ‘Expansion Cards’ for information, and in ‘System
BIOS and Setup’ to see whether your chosen settings are useable.
System BIOS
Check finally the system BIOS to ensure that it has not been
disturbed from the original settings. If the settings appear to have
altered, there may be a fault with the CMOS battery. See ‘System
motherboard’ and ‘System BIOS and Setup’.
The system’s disk drives
Refer also to Chapter 2, ‘Using your computer’.
Floppy disk drive
If you have problems accessing a diskette or floppy disk, check that
it is inserted correctly, that it has been correctly formatted, that it is
not write-protected, and that the permissions assigned by the BIOS
allow the intended access. Some application software also may not
allow you to read or write to floppy disks during certain other
operations, or until you are about to exit the programme.
5/4
FT1200 OWNER’S HANDBOOK
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.
Hard disk drive
SCSI drives
If you have just fitted a new SCSI drive, or device, check that you
have used a valid ‘ID’ that does not conflict with other SCSI drives
or devices is the system. Look in any documentation for
information.
On boot up, just after POST, a list is displayed of the devices
attached to the SCSI interface, which shows the device, its
parameters and the set ‘ID’.

Replacing the CMOS battery
The battery is a 3 volt lithium type (CR2032 or equivalent)
typically used in calculators, watches and other small, batterypowered electronic items. The average battery life is between 3
and 5 years.
Read carefully the following instructions before commencing work.
1.
Turn off the computer and unplug all power cords. Take
suitable anti-static precautions and remove the system unit
cover.
2.
Identify the battery holder, identified at position ‘17’ on the
motherboard diagram.
3.
Carefully disconnect and remove any expansion cards that may
obstruct easy access to the battery. Take note of any cable
positions before removal.
Warning
Do not use a metal or other conductive implement to remove the
battery. If a short-circuit is accidentally made between its positive and
negative terminals, it may cause the battery to explode.
4.
Lift the edge of the battery far enough to clear the base of the
holder, then slide the battery from under the contact spring.
5.
Taking care not to touch the top or bottom surface of the
battery, pick up the replacement with the positive (+) terminal
upwards and slide the battery into the holder from the same
side the old battery was removed.
6.
Replace any expansion cards you had to remove in step 4 and
replace the system unit cover.
7.
Dispose of the old battery according to the makers
instructions.
When you next turn on the computer you will have to run the
BIOS Set-up utility to enter the hardware configuration. See
‘System BIOS and set-up’ for guidance.

Upgrading the motherboard
Caution
Care must be taken in the purchase of upgrade parts to ensure both
compatibility with the system and the compliance with appropriate
approvals and certification, e.g. CE marking within Europe. Using
non-approved parts may invalidate your warranty and system approvals.
The only tool required to complete the installation of the upgrades
is a small cross-head screwdriver.
Read all the instructions through carefully before starting. The tasks
are not difficult, but if you do not feel confident about the work
involved, you may wish to have your supplier or service organisation
complete it for you.
Warning
Never carry out any work inside the computer with AC power applied.
Turn off the computer and unplug all power cords before starting work.
Adding more memory
DIMM specification
Memory can be fitted in three vertical DIMM sockets which must be
populated with gold contact, 3.3V, 72-bit unbuffered EDO type
DIMMs having 60 ns timing.
The three DIMM slots accept DIMMs of 16, 32 and 64 Mbytes
in any combination, to the maximum of 192 Mbytes.
Fitting and removing DIMMs
Note the indents along the connector edge, they prevent the
DIMM from fitting into the socket the wrong way round.

To remove a DIMM
1.
Gently press the tabs on both of the end clips at the same time.
This will release the DIMM and lift it out of its socket.
2.
Lift the module clear of its socket. Hold it by its ends and
avoid touching the metal contacts.
3.
Place the DIMM in suitable anti-static packaging.
When you have finished, replace and reconnect the drive module
you removed earlier, then refit and secure the system unit cover.
The first time you turn on the computer after adding or removing
memory, the change will be automatically detected by the system
BIOS, if an error message occurs check that you have:
♦
Correctly fitted the DIMMs in their slots.
♦
Installed DIMMs of the correct type.
It may be necessary to refit the original memory to check if there is
a problem with your new modules. If in any doubt contact your
supplier. Remember that all new DIMMs must carry the
appropriate approval markings etc. to avoid invalidating the system
certifications.
Upgrading the processor
The ZIF (zero insertion force) ‘type 8’ processor socket on the

suitable anti-static precautions and remove the main system
side panel. Detailed instructions for this are given in chapter 1.
Caution
If you are unfamiliar with the recommended anti-static precautions,
refer to the antistatic section at the rear of this handbook.
2.
If there are any expansion cards in the way, you may have to
remove them. Disconnect any cables connected to the cards,
remove the securing screws at the rear of the system unit, then
remove the cards.
◊ If the system was in use just before starting this procedure,
the processor will be hot, wait at least 15 minutes for it to
cool down.
3.
If there is no processor fan, a strong spring clip secures the
large heatsink to the processor. Release the end of the spring
from the hook on the front of the ZIF socket with care and
slide the heatsink clear.
◊ Handle carefully as there may be heat transfer compound
on the heatsink face.
◊ There may be a power lead for the fan if the processor has
one fitted. Take note of the fan power lead polarity before
releasing it from its board connection.
4.
A lever attached to the ZIF socket secures the processor in the
socket. Unhook the lever from under the clip in the locked
position. Lift it upright (at right-angles to the motherboard).
There may be a little stiffness at the beginning and end of the
lever’s movement.

ensure that the processor is installed in the correct orientation.
(The pin pattern is totally different at one end.) It will only fit
into the socket one way.
3.
Place the processor in the socket, making sure that it is
correctly aligned and that you do not bend or otherwise
damage the pins. Do not use excessive force.
4.
Move the ZIF socket lever to the locked position. Apply just
enough pressure to overcome the resistance offered by the
lever. Ensure that it is firmly hooked into its down position.
5.
Refit the heatsink if the new processor was supplied without
one and secure correctly the retaining spring. Ensure the
heatsink is central on the processor and is securely held.
◊ If the spring is no longer required, remove it completely by
disengaging it from its hook on the rear of the ZIF socket.
◊ The upgrade processor may have a fan power lead to be
connected to the pins on the board (PL73). The ‘overdrive’

SYSTEM BIOS AND SETUP
The basic input-output system (BIOS) is permanently encoded in
an area of read-only memory (ROM). It can be modified or
upgraded if necessary, but this is recommended to be undertaken by
an authorised engineer. It requires specialist software.
BIOS Setup is a utility within the computer BIOS. Its main
purpose is to allow you to view and alter the computer hardware
configuration. It is also used to configure various security and
power-saving options.
The current configuration is kept in a special area of memory, called
CMOS memory, and maintained by a small battery, so the
configuration is preserved while the computer is switched off, along
with other settings like the date and time.
Caution
The BIOS has been set in our factory for the optimum system
performance and operation. It is not advisable to alter any settings

Not long after turning on your computer, the Mitsubishi symbol
appears at the top right hand side of the screen:
While this symbol is displayed and the memory is counting, you can
press the F1 key to enter the BIOS Setup utility. You can only enter
the setup utility at this time and by this method. It will take a few
seconds for the utility to load.
Hint
A page is provided at the end of this chapter to make a note of your
current BIOS settings.

System BIOS and Setup
If Setup runs on its own
This can happen for three reasons:
♦
Power on self test (POST) detects a configuration error or
fault. This will result in either a BEEP code or one or more of
the error messages listed at the end of this chapter. If a fault
persists, make a note of error messages and the current
configuration settings before calling an authorised maintainer.
♦
The CMOS battery may be running down. You may get
spurious error messages. If this happens every time you turn on
the computer, you may have to change the battery,
instructions for this are given in the ‘Motherboard’ chapter.
♦
The configuration may have been changed, for example by the
addition of more system memory, a new hard drive, or an
expansion card. In this case you may have to define and check
the new configuration.
In any areas where the POST has detected changes, or there is some
contentious issue, the BIOS setup menu’s buttoned items will
change to show an arrowhead symbol. This can be followed down
through any further levels of menu until you arrive at the screen
with the change on it.
Control keys
A number of keys are used within the BIOS Setup utility, to select
items on the screen, and change the settings. The two lines at the
bottom of the screen indicate what you can do at any given time.
The following are the keys and their function:

System Summary
This page cannot be edited, but gives a summary of the system main
settings. Changes made in other pages will be reflected here. Make a
note of the information on this page before you progress any
further, or make any changes.
Devices and I/O ports
Serial ports A & B (COM1 & COM2)
This allows you to select the I/O ports and interrupts used by the
two serial ports. The system will normally auto-configure, so it is
best to leave these at the default settings.
Parallel port
This allows you to set the I/O port and interrupt used by the
parallel port. It should be left at ‘Auto-configure’ unless required to
be set to one of the following:
Parallel Port Mode
Standard
Extended
7/4
Description
Used for output only.
Bi-directional
Simple two-way data.
EPP
Enhanced Parallel Port mode.
ECP
Extended Capabilities Port mode.
FT1200 OWNER’S HANDBOOK
System BIOS and Setup
Any parallel port devices that you may wish to attach, such as a tape
streamer or external hard drive etc., should have full instructions
supplied with them that will tell you if the port capabilities need to
be manually altered to one of the extended options listed.
Mouse
This option enables the use of a mouse. The actual presence of the
mouse can then be detected by POST. You should not normally
disable this setting.
Diskette Controller
This option enables the use of the 3.5” floppy diskette drive. You
should not normally disable this setting.
Floppy disk drives
This lets you specify what diskette and floppy disk drives are fitted.
Diskette drive A which is fitted by default, is invariably a 1.44
Mbytes 3.5” drive. You will not be required to change this setting.
Video Setup
If selected this opens a screen which details the video controller and
the size of the video memory.
IDE Controller
This must be ‘enabled’ if the system is supplied with an IDE CDROM, but may be disabled if all drives are exclusively SCSI.
IDE Drives Setup
The motherboard has two IDE/ATA (Integrated Drive electronics
AT-Attachment) interfaces, supporting two drives on each.
However, the computer itself can accommodate only two IDE hard
disk drives, on the primary interface, so any removable-media
drives, typically a CD-ROM drive, should be connected to the
secondary interface.
FT1200 OWNER’S HANDBOOK
7/5
System BIOS and Setup
Hard disk drives
Hard disk size, type and mode, is auto-detected when the computer
is turned on, and the most suitable mode will have been selected.
Do not alter this mode as it may cause your hard disk to be
inaccessible, or the data to be lost.
Choosing any of the displayed drives opens a screen giving further
details of the drive.
Date and Time
Use this to adjust the motherboard’s Real Time Clock (RTC). This
clock is maintained by the CMOS battery.
Time
The time is in 24-hour format. Use the ‘control keys’ to move
around and change settings.
Date
The date is in the UK Day / Month / Year format. The procedure for
setting the date is the same as for the time.

Power-on Password
This option allows you to set a password that is required every time
the computer is turned on or rebooted. Only people who know the
password will be able to use the computer. The password can be up
to seven characters long.
To define a power-on password:
1.
In the Power-on Password dialog, type the password in the
‘Enter Power-on Password’ box, then press the DOWN
ARROW key.
◊ To preserve confidentiality, the password is not displayed
as you type it.
2.
7/6
Type the password once more in the ‘Enter Power-on
Password Again’ box.
FT1200 OWNER’S HANDBOOK
System BIOS and Setup
3.
If you want the computer to ask for the power-on password,
ensure that Password Prompt is set to “On”. If this option is
set to “Off”, the computer will still require the password but
will not ask for it.
◊ If you do not enter the password on start-up, the keyboard
is inoperative! To get round this you may have to boot
from a floppy disk in the A: drive.
When the computer is next turned on or rebooted, the user is
required to enter the password. If the Password Prompt is set ‘On’,
the following prompt will be displayed:
Type your password, then press Enter.
If the Password Prompt option is set to ‘Off’, the user is not
prompted at all but will wait for the user to type the password and
press ENTER. It is important that authorised users of the computer
are told to expect this, or they may think that the computer has
stopped working.
The user is allowed three attempts to enter the correct password. If
they fail the computer is locked and must be switched off. Turning
the computer on again restarts the sequence.
To change or delete the password, select the appropriate option.
You may be asked for the existing password to allow any change or
deletion.
Administrator Password
The administrator password can be set up in the same way as a
power-on password. If you define both an administrator and a
power-on password, the computer will only allow you to enter
Setup by using the Administrator’s password.
Start Options
Certain features can be set or enabled automatically when the
computer boots.
FT1200 OWNER’S HANDBOOK
7/7
System BIOS and Setup
Keyboard Numlock State
If set to ‘On’ (default), the keys on the numeric keypad (on the
right-hand side of the keyboard) will produce numbers when
pressed. If ‘Off’, these keys provide cursor control functions instead.
Keyboard speed
This sets the speed (frequency) at which a pressed key will repeat;
either ‘Fast’ (default) or ‘Normal’.
Disketteless Operation
If this is ‘Disabled’, POST will look for and test the diskette drive,
and report an error if the drive is faulty or missing. If ‘Enabled’,
POST will omit the test and continue, provided that another boot
device is available (i.e. the hard disk drive).
Displayless Operation
If this option is ‘Disabled’, POST will look for an attached monitor
and report an error if it is faulty or missing. If ‘Enabled’, POST will
allow the computer to start without a monitor.
Keyboardless Operation
If this option is ‘Disabled’, POST will look for an attached
keyboard and report an error if it is faulty or missing. If ‘Enabled’,
POST will allow the computer to start without a keyboard.
Start-up Devices
These options allow you to specify where the BIOS looks for an
operating system when it boots. If the computer cannot locate an
operating system on the First Startup Device, it tries the Second
Startup Device.
Note that if the First Startup Device is set to ‘Disabled’, the
computer will be unable to boot.
By default, the First Startup Device is ‘Diskette Drive 0’ and the
Second Startup Device is ‘Hard Disk 0’. this should not normally
need to be changed.
7/8
FT1200 OWNER’S HANDBOOK
System BIOS and Setup
Power On Self Test
The POST can be selected to either run only a ‘Quick’ set of tests
or a more thorough (but longer) ‘Enhanced’ set.
Virus Detection
If this option is ‘Enabled’, each time the computer boots the BIOS
will check the startup device to find if a boot sector virus has crept
in. This is not an infallible check against the newer types of viruses,
but it can help.
Advanced Setup
Any settings changed here, if incorrect, may cause the system to halt or
may cause your software to malfunction. A warning about this appears
on the screen when you choose Advanced Setup from the menu.
Cache Control
A simple dialog allows you to enable or disable the computer’s
memory cache. Some older software is speed sensitive and on rare
occasions you may need to disable the cache.
ROM Shadowing
To shadow ROM means to copy its contents into the computer
system or random-access memory (RAM). ROM has longer access
times and the processor can access RAM faster than ROM. Also, the
contents of RAM can be cached for even greater performance. All of
the computer system BIOS ROM is shadowed.
The ROM Shadowing option allows you to shadow video BIOS
and up to three 32 Kbytes areas of expansion card ROM (that is,
ROM fitted on ISA or PCI expansion cards) addressed between
C8000h and DFFFFh.
Caution
Shadowing is only appropriate for expansion card ROM. It must not be
enabled for expansion card RAM.
FT1200 OWNER’S HANDBOOK

System BIOS and Setup
PCI Settings
The only configurable PCI setting is Palette Snooping. This can be
‘Enabled’ or ‘Disabled’ and should be enabled only for PCI video
expansion cards that specify it as being required.
Universal Serial bus (USB)
This is available for future use as more USB devices become
available. Leave set to ‘enabled’.
Memory settings
This page sets the level of memory testing. The available settings
are, ‘Disabled’, ‘Correction’, ‘Checking and Correction’. The
default setting is for ‘Correction’.
Pentium Pro features
The only setting is for BU Enable and this should be left ‘Enabled’.
Plug and Play
Enabling the Plug and Play adapter configuration will auto-configure
any Plug and Play cards but any ISA adapters which do not support
Plug and Play will require the system resources to be registered.
There is a separate option for each resource; memory, I/O ports,
DMA and interrupts. Some areas are allocated by the system and are
not shown. Each resource can be set to either Plug and Play or ISA
legacy. If shown as Plug and Play, it is assumed by the system not to
be in use by any ISA card or device and therefore will be made
available for the PCI auto-configure process.
Although many ISA cards are very simple to configure, the resources
they use, if any, must be registered in the BIOS. See the chapter
dealing with ‘Expansion’.
Error Log
Any errors reported during the POST routine will be logged in the
Error log. The log will display up to three errors detected
It can be reset, but should only be cleared after a note is made of the
faults during any diagnostic work.

Power Management
The power management features provided aim to reduce the
amount of electricity consumed by your computer if it should be
left idle. If your system has Apricot power management software the
BIOS settings should all be set to disabled as standard. That will
allow use of the software to pre-program power restore events and
operations. (incoming messages, alarm calls etc.)
The following menu is available:

‘Disable’, ‘Enable’.*
(* see warning below)
Caution
The monitor supplied with your computer is designed to work with these
energy-saving features. If you use another, or older monitor, It may not
be compatible. It may cause permanent damage.
Beep codes
No beeps. If no beeps are heard at all the speaker may be
disconnected or there may be a speaker circuitry fault.
One short beep. Marks the completion of POST and no functional
errors found. You will also get a single beep if you press an invalid
key for a power-on password.
Two short beeps. Indicates and draws your attention to an error
during POST. This should be accompanied by an error message.
Three short beeps. System memory error, normally accompanied
by code 201. Beeps are used when the video cannot display the
code.
Continuous beep. Could indicate a serious failure of the system
motherboard, or a failure of the speaker circuitry.
FT1200 OWNER’S HANDBOOK
7/11
System BIOS and Setup
Repeating short beeps. Usually indicative of a keyboard key stuck
down, but may be due to the keyboard interface failing.
One long and one short beep. POST has detected an error on the
video adapter in the system. There may be no display on the screen.
One long and two short beeps. This means that either the video
system is faulty, or that a video I/O adapter ROM is not readable.
Two long and two short beeps. The video subsystem cannot be
supported by the main system POST. This can occur when the
video subsystem is replaced or changed on site.
Many of these following codes indicate a serious fault and the

APPENDIX
Suitable antistatic precautions
Cleaning and transporting
A1
ANTI-STATIC
PRECAUTIONS
Static electricity can cause permanent damage to electronic
components. You should be aware of this risk, and take precautions
against the discharge of static electricity into the computer.
Static electricity can be generated by moving on a chair, brushing
against desks or walls, or simply walking across an ordinary carpet.
Items handed from one person to another, or being wrapped or
unwrapped, can acquire a static charge. Air conditioning systems
can also result in very high levels of static.
Clothing made of synthetic fibres is particularly likely to generate
static electricity. This static electricity is often completely unnoticed
by the wearer, but can be sufficient to cripple or destroy sensitive
electronic components in computers.
The computer is at risk from static discharge while the top cover is
off, as the electronic components of the motherboard are exposed.
Memory modules, cache upgrades and OverDrive processors are
other examples of electrostatic sensitive devices (ESSDs).
All work that involves removing the cover must be done in an area
completely free of static electricity. We recommend using a Special
Handling Area (SHA) as defined by EN 100015-1: 1992. This
means that working surfaces, floor coverings and chairs must be
connected to a common earth reference point, and you should wear
an earthed wrist strap and anti-static clothing.
It is also a good idea to use an ionizer or humidifier to remove static
from the air.
♦
When installing any upgrade, be sure you understand what the
installation procedure involves before you start. This will
enable you to plan your work, and so minimise the amount of
time that sensitive components are exposed.
♦
Do not remove the system unit cover, nor the anti-static bag or
wrapping of any upgrade, until you need to.
A1/1
Anti-static precautions
A1/2
♦
Handle static-sensitive items with extreme care. Hold
expansion cards and add-on components only by their edges,
avoiding their electrical contacts. Never touch the components
or electrical contacts on the motherboard or on expansion
cards. In general, do not handle static sensitive items
unnecessarily.
♦
Keep all conductive material, foodstuffs and especially liquids,
away from your work area and the open computer.
A2
CLEANING AND
TRANSPORTING
Cleaning the computer
Do not use solvents or abrasives, they might damage the system unit
surfaces.
Do not use aerosols or sprays near any part of the system, in
particular, air vents or grills, ports, or removable-media drives, as
microscopic droplets can remain in the air for some time and then
be sucked in when you switch on and cause irreparable damage.
Warning
Turn off the system unit and unplug all power cords before cleaning or
moving the computer.
The system unit
♦
Occasionally wipe the outside of the system unit with a soft,
slightly damp, clean cloth.
♦
Occasionally check the air vents on the rear and sides of the
system unit. Dust and fluff can block the vents and limit the
airflow. A small, clean, soft brush may be useful.
♦
Occasionally clean the removable media drives using a special
disk cleaning kit. These are available from many sources
including your Apricot dealer.
The monitor
Occasionally wipe the monitor with a soft, slightly damp, clean
cloth. It is best to use antistatic glass cleaner on the monitor screen
to help prevent dust adhesion. Do not spray glass cleaner directly
onto the screen, it could run down inside the case and damage the
circuitry.
A2/1
Cleaning and Transporting
The keyboard
When necessary, clean the keycaps with a slightly damp clean cloth
and a minimum amount of a non-abrasive cleaning agent.
Regularly check the keyboard cable for wear and tear, particularly
near table or shelf edges.
Take care not to spill any liquid or drop small objects, e.g. paper
clips or staples, onto the keyboard. Follow these steps if this should
happen to the keyboard and it stops working:
1.
Switch off and unplug the keyboard.
2.
If the liquid is sticky or viscous, unplug the keyboard and call
your supplier or an authorised maintainer.
3.
If the liquid is thin and clear, try unplugging the keyboard,
turning it upside down to let the liquid drain out, and drying
it for at least 24 hours at room temperature. If the keyboard
does not work, call your supplier or an authorised maintainer.
4.
If a solid object drops between the keys, turn the keyboard
upside down and shake it gently. Do not probe between the
keys as this may cause serious damage.
The mouse
The mouse tends to be used heavily and so is susceptible to damage,
but a little care should minimise this.
Dust and fluff often accumulates in the ball tracking mechanism of
the mouse and should be checked for regularly. To clean the mouse
follow this procedure:
A2/2
1.
Unplug the mouse, turn it upside down and locate the plastic
cover that holds the ball in place. Depending on the model,
the plastic cover can be removed either by rotating it counterclockwise or by sliding it forward slightly.
2.
Remove the cover and set it aside. Then cupping one hand
over the underside, turn the mouse back the right way up. The
ball should drop into your hand.
3.
Blow gently into the mouse to remove any dust that has
collected there.
Cleaning and Transporting
4.
Inside the mouse there are three small rollers. Using a cotton
swab moistened with a solvent cleaner, gently wipe off any oil
or dust that has collected on the rollers, rotating them to reach
all of their surfaces.
5.
Use clear water, or water with a mild detergent, to clean the
ball. Then dry it with a clean, soft cloth.
6.
Put the ball back in its socket and replace the plastic cover. It
should click into place.
The mouse cable should also be regularly checked for wear and tear,
especially near table or shelf edges.
Transporting the computer
Use common sense when handling the computer. Hard disks in
particular can be damaged if the computer is dropped or handled
roughly.
Do not transport the computer with either a floppy disk or a CDROM left in the drives, as they may cause damage both to the
media and to the drive.
Do not attempt to pick up the computer using either of the drives
as a lifting point.
Do not try to move the computer while it is plugged into the AC
power supply or with any other cables, (network, printer etc.), still
attached and especially with the monitor on top.
If you need to transport the computer any great distance, use the
original packing materials.
Warning
The computer is correctly set up to operate with the AC supply in the
country in which it first sold. If you wish to use the computer in another
country it may not be suitable. Consult your supplier or an authorised
Apricot dealer.
