Clean and as dust free as possible.

♦

Well ventilated and away from sources of heat includ-

♦

ing direct sunlight.

Well away from sources of water or damp.

♦

Stable and protected from sources of vibration or

♦

physical shock.

◊

during an electrical storm.

Power Supply

Checking the Input Voltage Setting

A 200 watt (peak) power supply is integrated into the chassis
to provide power for the motherboard, add-in cards, and
peripheral devices. A switch on the back panel can be used to
set the power supply to operate at:

115 V AC (in the range of 90 - 127 V AC), or

♦

230 V AC (in the range of 180 - 255 V AC)

♦

To verify that your system has the correct setting for your
environment, check the input power selection switch. This
should already be correctly set for the country of sale.

achieved simultaneously.

Before Installing Optional Items

Before installing other items, such as drives, add-in cards,
etc., connect a keyboard and a monitor to the system, switch
on and let the power-on self test (POST) run. This will be
followed by initialisation of the pre-installed Operating
System software, during which you will be asked to enter
personal registration details.

Once this has been fully completed, you can shut down the
operating software, turn the power off, then install any
drives, add-in cards, or upgrades, the instructions for which
are given in the following chapters.

This is to allow ‘Plug and Play’ add-in cards and their special
features to be correctly detected and configured.

1/6 LS700 HANDBOOK

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.

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.

System motherboard

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 3/9

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.

WWAARRNNIINNGG

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.

5. With your fingers, gently pry the battery free from its
socket. Note the "+" and "-" orientation of the battery.

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

♦

NNOOTTEE

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.

NNOOTTEE

The board has a connector for an optional off-board speaker.
When installing an off-board speaker (refer to chapter 2) you
must remove the jumper that enables the onboard 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 only tin-lead,

♦

72-pin, 50 or 60 ns EDO DRAM.

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.

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.

NNOOTTEE

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.

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

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

Sets the status of the IRQ. The options are:

♦

Available (default)

Used By ISA Card

♦

The PCI auto-configuration code looks here to see if these IRQs
are available for PCI add-in cards. If an IRQ is available, the PCI
auto-configuration code can assign the IRQ to be used by the
computer. If your computer has an ISA add-in card, select Used
By ISA Card for one of these IRQs.
