adapter.
Warning
Always ensure that the system unit is fully
reassembled before powering it up.
10
Upgrading memory
The FT//e Pentium motherboard has eight SIMM sockets
which support a maximum of 256 Mbytes of RAM. These
eight sockets are arranged in two banks of four. If SIMMs
are installed in a bank all four SIMMs must be identical.
The eight SIMM sockets are located beneath the drive bay
as shown in the following illustration.
MM8

Installing SIMMs
Obtaining access
To obtain access to the SIMM sockets you must remove,
the side panel as described in Removing the side panel,
and the drive cradle as described in Removing the drive
cradle.
Removing SIMMs
If you wish to install an upgrade in a bank which is already
occupied you must first remove the existing SIMMs. For
each SIMM in the bank:
1. Lever the metal clips on each side of the socket
gently away from the SIMM using your forefingers.
2. Place your thumbs on the top edge of the SIMM and
move it gently towards the vertical.
3. When the SIMM has rotated through 20°, taking care
to avoid touching any of the components on the
SIMM, grip the top corners of the SIMM between
thumb and first finger and carefully pull the SIMM out
of the socket.
Inserting SIMMs
For each socket in the bank:
1. The SIMM will only install in one orientation. There
is a cutout at one end of the SIMM next to the
connector strip.
Hold the SIMM with the cutout on the left and the
metal connector strip nearest the motherboard.
13
2. Position the SIMM above the socket with the SIMM
tilted slightly towards the rear of the system unit.
3. Lower the SIMM into the socket, and ensure that
the SIMM is properly located in the connector.
4. Pushing gently on the top corners rotate the SIMM
towards the horizontal until it clips into place. Do not
use excessive force.
If the SIMM will not rotate easily remove it and start
again.
5. If the SIMM is properly located the SIMM should
remain in position held by the securing clips, and
with a small plastic lug through the holes on either
side of the SIMM.
Once you have installed all the SIMMs you can reassemble
the system.
Warning
When replacing the drive cradle, make sure that you keep
the cradle locating pins as far as possible into the cutouts
at the front of the drive cradle, while you swivel the cradle
back into place.
14
Processor upgrades
The FT//e Pentium motherboard is fitted with a Zero
Insertion Force (ZIF) processor socket, ready for higher
performance Pentium variants as they become available.
The FT//e Pentium motherboard is ready to accept any
processor with a Pentium compatible pinout, and a
maximum external clock speed of 60MHz.
15
Removing the processor
Before installing the upgrade processor you must first
remove the existing processor. The processor is at the
front left of the motherboard beneath the fan assembly.
Instructions on locating the socket and removing a
processor are given below.
1. Remove the side panel as described in Removing
the side panel.
2. Note the position of all adapter cards and adapter
cabling.
3. Disconnect all adapter cables and remove the
adapters.
4. Disconnect the fan power cable, and remove the
two screws that secure the fan assembly.

The first and last 15° of movement may require
considerable effort. Apply just enough pressure to
overcome the resistance offered by the lever.
8. Once the processor is free of its socket lift it out of
the system unit and place it on the anti-static foam
provided with the upgrade processor.
18
Installation
You are ready to install your new upgrade processor.
1. The upgrade processor and socket are keyed to
ensure that the processor can only be installed in
one orientation.
One corner of the socket has an extra hole inside
the others, the processor has a corresponding extra
pin. The processor has a small dot of paint on its
top surface to indicate the corner with the extra pin.
If the processor has a heatsink fitted the paint dot
may not be visible. Use the illustration below to help
you identify the keyed corner.

Warning
If the processor is misaligned it will not go into the
socket, and any attempt to force it will damage the
processor, or the socket, or both.
3. Gently insert the upgrade processor making sure
that it is correctly aligned with the socket and that
you do not bend or otherwise damage the pins.
4. Once you are certain that all the pins on the
processor are in the holes in the socket carefully
move the securing lever to the locked position.
The lever may require a considerable amount of
force in order to lock the processor in place. Take
care to exert no more force than is necessary.
5. You may now reassemble the system unit.
