System description and installation
Secondary Fan Specifications
This chassis has been tested for adherence to thermal
specifications using a single system fan and a full
complement of typical add-in cards and peripherals.
Because the power and cooling requirements for add-in card
components vary widely, this testing cannot guarantee that
every add-in card will meet its particular thermal
requirements in all possible system configurations.
If you integrate the system with add-in cards that draw
significant power, it is recommended that you install a front
cooling fan. If you add a secondary fan, it must meet these
specifications. Full installation information can be found in
chapter 2. Suitable fans can be obtained from your Apricot
supplier.

LS700 HANDBOOK
System motherboard
♦
Industry standard diskette drive controller that supports
720 KB, 1.44 MB, and 2.88 MB floppy drives (at 135
tracks per inch); and the older 360 KB and 1.2 MB drives.
BIOS Features
The BIOS, from American Megatrends Inc. (AMI), provides
ISA and PCI compatibility. The BIOS is contained in a
Flash memory device soldered to the motherboard. The
BIOS provides the POST, the Setup program, a PCI and
IDE auto-configuration utility, and BIOS recovery code. For
full information see the ‘BIOS and Setup’ chapter.
PCI Auto-configuration
The PCI auto-configuration utility works in conjunction
with the Setup program to support using PCI add-in cards
in the computer. When you turn on the power after
installing a PCI card, the BIOS automatically configures
interrupts, DMA channels, and I/O space.
Since PCI add-in cards use the same interrupt resources as
ISA add-in cards, you must specify the interrupts used by
ISA cards in the Setup program.
Expansion Slots
The
motherboard
has
two
dedicated
16-bit
ISA/AT-compatible and three dedicated PCI-compatible
expansion slots. Another expansion slot is a combination slot
that can be used for either a PCI or an ISA card. This allows
you to install a maximum of six add-in cards.
Real-time Clock and CMOS RAM
The I/O controller provides a real-time clock and CMOS
RAM. You can set the time for the clock and the CMOS
values by using the Setup program described in the BIOS
Chapter. This will need to be carried out if there is a
requirement to change the CMOS battery, as detailed over.
LS700 HANDBOOK

System motherboard
CMOS Battery
A battery on the motherboard keeps the clock and values in
CMOS RAM current when your computer is turned off.
The average battery life is between 3 and 5 years.
WARNING
The CMOS battery is a lithium type. Do not use a metal tool
to remove the battery. An accidental short circuit may cause
the battery to explode. Dispose of the battery according to the
battery manufacturers recommendations.
To replace the battery:
1.
Observe the precautions in “Before You Begin” (see
page 1 of chapter 2).
2.
Turn off all peripheral devices connected to the
computer.
3.
Turn off the computer and unplug the power cable.
4.
Remove the computer top and access covers.

USB Interface Support
The USB ports permit the direct connection of two USB
peripherals without an external hub. If more devices are
required, an external hub can be connected to either of the
built-in ports. The motherboard supports the standard
universal host controller interface (UHCI) and uses standard
software drivers that are UHCI-compatible.
Features of the USB include:
♦
Support for self-identifying, hot-pluggable peripherals
♦
Automatic device configuration
♦
Support for isochronous and asynchronous transfers
over the same set of wires
♦
Support for up to 127 physical devices
♦
Bandwidth and low latencies appropriate for telephony,
audio, and other applications
♦
Error handling and fault recovery built into protocol
NOT E
Computers that have an unshielded cable attached to the USB
port risk causing radio frequency interference (RFI). Use
shielded cable for all devices attached to either USB port.
Speaker
An optional speaker is mounted on the motherboard. The
speaker provides audible error code information (beep codes)
during the POST if the BIOS cannot use the video interface.
For beep code descriptions, see the troubleshooting chapter.
NOT E
The board has a connector for an optional off-board speaker.

How to Install Memory
The motherboard has four 72-pin, tin-lead SIMM sockets that
support from 8 MB to 256 MB of memory. The sockets are
arranged as banks 0 and 1. Two sockets make up one bank
(see figure 40).
When adding memory, follow these guidelines:
♦
When adding SIMMs, use
72-pin, 50 or 60 ns EDO DRAM.
only
tin-lead,
◊ Faster devices will not improve system performance.
♦
When you install SIMMs, you must fill both sockets of
the bank.
♦
The computer automatically detects the installed
memory, so it doesn’t matter which bank is used, as
long as both sockets in the bank are filled.
◊ Because of limited space on the motherboard, it
might be easier to install SIMMs in bank 0 first.
LS700 HANDBOOK
4/5
Upgrading
♦
Both SIMMs in one bank must be identical.
◊ For example, do not install a 4 MB SIMM in one
socket of bank 0 and an 8 MB SIMM in the second
socket of bank 0.
♦
You may use a pair of SIMMs in bank 1 that are of a
different value to those in bank 0.
NOT E
The motherboard supports parity (x36) or non-parity (x32)
SIMMs. Error checking and correction is supported with parity
and ECC SIMMs. There is no error checking and correction
with non-parity SIMMs.

CAUTION
Electrostatic discharge (ESD) can destroy components or severely
limit their working life. Follow the recommended antistatic
precautions as given in the appendix.
4.
Holding the SIMM only by the edges, remove it from
its antistatic package.
Figure 41. Installing a SIMM
5.
Position the SIMM at about a 45° angle relative to the
motherboard.
◊ Make sure the small notch in the middle of the
bottom edge of the SIMM aligns with the notch in
the SIMM socket.
6.
Insert the bottom edge of the SIMM into the SIMM
socket and make sure it is seated firmly.
◊ The SIMM is not symmetrical, so will only seat one
way in the socket.

LS700 HANDBOOK
Upgrading
7.
When the SIMM seats correctly, hold it at each end
and gently push the top edge towards the retaining clips
of the connector until the SIMM snaps into place.
◊ If the SIMM does not install correctly, gently
spread the retaining clips just enough so that you
can pull away the top edge of the SIMM and try
again.
8.
Reinstall and reconnect any parts you removed or
disconnected to gain access to the SIMM sockets.
9.
Replace the computer cover.
Memory detection is mostly automatic, but if you get an
error message, check that:
♦
You have used a supported SIMM value.
♦
Both SIMMs in the bank are the same.
How to Remove Memory
To remove a SIMM, do the following:
1.
Observe the precautions in ‘Before You Begin’ (see
page 1 of chapter 2).
2.
Turn off the computer and unplug the power cable.
3.
Remove the computer top and access covers.
4.
Gently spread the retaining clip at each end of the
SIMM socket, just enough to allow you to tilt the top
edge of the SIMM to an angle of about 45°.
5.
Holding the SIMM only by the edges, lift it away from
the socket, and store it in an antistatic package.
6.
Reinstall and reconnect any parts you removed or
disconnected to gain access to the SIMM sockets.

BIOS AND SETUP
This chapter explains how to use the BIOS Setup program.
You can use the Setup program to change the computer’s
configuration information and boot-up sequence.
Setup information is stored in CMOS random access
memory (RAM) and is backed up by a battery on the
motherboard when power to the computer is off.
Overview of the BIOS Setup Program
To enter the Setup program, turn the computer on and press
<F1> when you see the message:
Press <F1> Key if you want to run SETUP
You have about five seconds to press <F1> before the boot
process continues.
NOT E
For reference purposes, you should write down the current Setup
settings on the space provided at the end of this chapter. When
you make changes to the settings, update this record.
When you enter the Setup program, you will see the Main
screen. Listed along the top of the display are three other
screens: Advanced, Security, and Exit.
Select a screen by pressing the left <←> or right <→> arrow
keys. Use the up <↑> or down <↓> arrow keys to select
items within a screen. Use the <Enter> key to select an item
you want to change. For some items, pressing <Enter>
brings up a subscreen. After you have selected an item, use
the arrow keys to change the setting.
The following table provides first an overview of function
keys in the Setup program, then gives an overview of the

If this field is set to Disabled, the ISA Shared Memory Base
Address field (described below) will not appear.
This field should be enabled only when you are using a nonPlug and Play ISA add-in card (legacy card) that requires
non-ROM memory space. For example, video capture cards
that have video buffer memory.
By default, allocation of upper memory is as follows:
memory from C0000h-C7FFFh is automatically shadowed.
(This memory range is typically reserved for video BIOS.)
Memory from C8000h-DFFFFh is initially unshadowed.
The BIOS scans this range for any ISA add-in cards that
may be present and notes their location and size.
The BIOS will then automatically configure the PCI and
Plug and Play devices, shadowing the ROM requirements
(other than video) into the area above E0000h until that area
is full. It will then assign additional PCI and Plug and Play
add-in cards to the area between C8000h and DFFFFh. If
an ISA legacy card has non-ROM memory requirements, the
autoconfigure routine may write into an area that is needed
by the ISA add-in card.
LS700 HANDBOOK
5/23
BIOS and setup
The ISA Shared Memory Size parameter signifies to the
autoconfigure routine that this block of memory is reserved
and should not be shadowed.
Shadowing copies a block of memory from an add-in card’s
ROM to the same address in computer DRAM memory.
This improves computer performance.
ISA Shared Memory Base Address
Sets the base address for the ISA shared memory. The
options are:
♦
C8000h (default)
♦
CC000h
♦
D0000h
♦
D4000h
♦
D8000h
♦
DC000h
This setting could affect the ISA Shared Memory Size field.
The value entered in the ISA Shared Memory Size field
cannot extend to the E0000h address. For example, if a size
of 64 KB were selected, options D4000h, D8000h, and
DC000h would not appear.
If the ISA Shared Memory Size field is disabled, this field
will not appear.
IRQ 3, 4, 5, 7, 9, 10, 11, 14, 15

software guide or contact the software supplier.
Make a note of any symptoms, error codes, or display
messages before calling your supplier or maintenance
provider
Problems when starting
If you suspect a blown fuse
In the United Kingdom, and some other countries, AC
plugs contain fuses. If the fuse in the AC plug blows when
you turn on the computer, this may be caused by an AC
power surge, but may be a symptom of problems with the
computer or its peripherals. Follow these steps:
1.
Turn off the computer and unplug all power cables and
unplug and disconnect all peripherals.
2.
If no cause is apparent, replace the blown fuse with one
of the same rating, reconnect the system unit power
cable and try to turn it on again.
3.
If the replacement fuse blows, call your supplier or
maintenance provider.
4.
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.
Power-on self-test (POST)
Whenever the computer is turned on, the power-on self-test
(POST) routine tests 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.
LS700 HANDBOOK

Troubleshooting
If POST detects a hardware fault, one or more POST error
codes and messages are displayed. Your first action should be
to turn off the computer, wait at least 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. Some of the
messages that might appear during the boot sequence:

Replace it with a system diskette and press F1.
The diskette is either not formatted or defective. Replace
it with a system diskette and press F1.
The hard disk has no active, bootable partition or is not
formatted. Insert a system diskette, press F1, and format
the hard disk as described in your operating system
manuals.
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.
This may indicate a fault in the diskette or hard disk
drive, or perhaps a damaged system diskette. Make sure
that the Startup Device options are correctly specified
with the BIOS Setup utility. If the problem persists
contact your supplier or authorised maintainer.

Troubleshooting
Connections
Check that all power and signal cables are securely connected
to the correct port on the computer.
The two serial ports 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.
Monitor
If there is no display check that the monitor is turned on,
and the brightness and contrast controls are not too low.
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.
System BIOS
Check finally the system BIOS to ensure that it has not been
disturbed from the original settings. a Notes area is provided
within the ‘System BIOS and Setup’ chapter to make a note
of your current or original BIOS settings.
If the settings appear to have altered, there may be a fault
with the CMOS battery. See ‘System Motherboard’ and
‘BIOS and Setup’.

Troubleshooting
The system’s disk drives
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.
Optional 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
If you encounter problems accessing any IDE hard disk
drive, use the BIOS Setup utility to check that the drive is
correctly specified, and that the drive’s controller is enabled.
Check also that the disk has been correctly formatted, and
that the permission assigned by the operating system allow
the intended access.
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’.

ANTISTATIC 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.
1
Antistatic precautions
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.
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.
The keyboard
When necessary, clean the keycaps with a slightly damp clean cloth
and a minimum amount of a non-abrasive cleaning agent.
1
Cleaning and Transporting
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:
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.
4.
Inside the mouse there are three small rollers. Using a cotton
swab moistened with a solvent cleaner, gently wipe off any oil
Cleaning and Transporting
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.
