Electrical Safety
CAUTION:
Electrical current from power, telephone, and
communication cables can be hazardous. To avoid any
shock hazard, disconnect all power cords and cables as
described in the following information.
For your safety, always do the following before removing
the cover:
1. Shut down all programs as described in your
operating-system documentation.
2. Turn off the computer and any attached devices, such
as printers, monitors, and external drives.
Note: personal computer users in the United
Kingdom who have a modem or fax machine
attached to their computer must disconnect the
telephone line from the computer before unplugging
any power cords (also known as power cables).
When the computer is reassembled, users must
reconnect the telephone line after plugging in the
power cords.
2
Installing Options in Your Personal Computer
3. Unplug all power cords from electrical outlets.
4. Disconnect all communication cables from external
receptacles.
5. Disconnect all cables and power cords from the back
of the computer.
Note: Do not reconnect any cables or power cords
until you reassemble the computer and put the cover
back on.
CAUTION:
Never remove the cover on the power supply. If you
have a problem with the power supply, have your
computer serviced.
Handling Static-Sensitive Devices
Have you ever walked across a carpeted floor, then
touched an object and received a small electrical shock?
That's static electricity, and although harmless to you, it
can seriously damage computer components and options.
Important
When you add an option, do not open the
static-protective package containing the option until
you are instructed to do so.
When you handle options and other computer
components, take these precautions to avoid static
electricity damage:
Ÿ Prevent others from touching components.
Ÿ When you are installing a new option, touch the
static-protective package containing the option to a
metal expansion-slot cover or other unpainted metal
surface on the computer for at least two seconds.
This reduces static electricity in the package and your
body.
Ÿ When possible, remove the option and install it
directly in the computer without setting the option
down. When this is not possible, place the
static-protective package that the option came in on a
smooth, level surface and place the option on it.
Ÿ Do not place the option on the computer cover or
other metal surface.
Ÿ Limit your movement. Movement can cause static
electricity to build up around you.
Ÿ Always handle components carefully. Handle
adapters and memory-modules by the edges. Never
touch any exposed circuitry.

Adapters
Adding an adapter, such as a communication or audio
adapter, extends the capabilities and power of your
computer. Your computer has adapter connectors called
expansion slots, which are located on a riser card.
Riser Configurations
Ÿ PC 350 riser card
The PC 350 riser card has five 16-bit, industry
standard architecture (ISA) bus expansion slots (one
on the other side), and three 32-bit, peripheral
component interconnect (PCI) bus expansion slots.
Three of the ISA/PCI slots are shared, and two of the
ISA slots are dedicated. You can use only one ISA or
PCI adapter per shared slot.
The following information describes the expansion slots
that are available on each type of ISA/PCI riser card.

Ÿ PC 330 riser card
The PC 330 riser card has three full-length, 16-bit,
industry standard architecture (ISA) bus expansion
slots and three 32-bit, peripheral component
interconnect (PCI) bus expansion slots. All three of
the ISA/PCI slots are shared. This means that you
can use only one ISA or PCI adapter per shared slot.

Plug and Play
Configuration/Setup Utility program
Plug and Play is a technology designed to automate and
simplify the setup and configuration of your computer
when you install new options. Plug and Play adapter
support is built into the system board in your computer.
Within the Configuration/Setup Utility program, the ISA
Legacy Resources screen, shows personal computer
resources, that are typically required by adapters:
Plug and Play Adapters
Ÿ I/O port address
Ÿ Memory address
Ÿ Interrupt request (IRQ) line
PCI adapters generally support Plug and Play. Some new
ISA adapters also support Plug and Play.
A Plug and Play adapter comes with identification and
configuration specifications set in memory on the adapter
to provide installation information to the computer
during startup. This information is sensed by the
input/output (I/O) bus and interpreted by the computer
basic input/output system (BIOS). The BIOS routines then
automatically configure the adapter around the resources
already in use by other devices.
Legacy Adapters
If an adapter you install is not Plug and Play compatible,
the Configuration/Setup Utility program can help you
manually configure the adapter. Adapters that are not
Plug and Play compatible are known as legacy devices.
10
Installing Options in Your Personal Computer
Ÿ Direct memory access (DMA) channel
From the Configuration/Setup Utility program screens
you can select available resources for the adapter you are
installing. Resources not currently being used by
adapters that are already installed in your computer are
listed as [Available]. The system resources that are in
use by other devices are listed as a [System Resource].
Notes:
1. Refer to the documentation that comes with the
adapter for information on required system resources.
Then make the appropriate jumper or switch settings
on the adapter.
2. If you have a resource conflict, set the resources used
by the ISA legacy adapter to [Not available]. This
will manually configure the ISA legacy adapter to
that specific computer resource. Once Plug and Play
detects that a resource is not available, it will skip it,
and reconfigure to other available system resources.

System Memory
System Memory
You can add system memory4 to your computer and
increase your system performance by providing more
DRAM storage. Your computer has four SIMM
connectors and one DIMM connector. Be sure to install
SIMMs in matched (identical) pairs. After the memory
modules are installed, the Plug and Play feature of the
Configuration/Setup Utility program will automatically
detect the additional memory modules.
You can increase system memory in one of four ways:
Ÿ You can install matched-pair, single in-line memory
modules (SIMMs) into the vacant SIMM connectors
on the system board.
Notes:
1. Memory modules can have a maximum height of 1.2
inches.
2. Install only parity SIMMs/DIMMs to enable parity.
3. A mix of parity and non-parity SIMMs/DIMMs
will configure as non-parity.
4. A mix of EDO1 and FP2 SIMMs/DIMMs will work,
provided that matched pairs are installed in each
bank.
5. Your PC supports industry standard 72-pin tin-lead
SIMMs and 168-pin gold-lead DIMMs.
Ÿ You can replace smaller matched-pair SIMMs with
larger ones.
Ÿ You can install matched-pair, dual in-line memory
modules (DIMMs) into the vacant DIMM connector
on the system board.
Ÿ You can remove the dual in-line memory module
(DIMM) from the DIMM connector on the system
board and replace it with a larger one.

Internal Drives
Drives connect to your computer with cables. Your
computer has three types of internal drive cables:
Ÿ A four-wire power cable connects to most drives.
Two types of power cables and connectors are
provided, allowing you to add drives with different
types of connectors. One of the drive power cables
connects to the installed diskette drive. If a hard disk
drive is installed, one of the drive power cables is
attached to this drive.
Ÿ A flat-ribbon signal cable connects internal diskette
drives and certain tape drives.
– The cable for the PC 330 has two drive
connectors. A third, unique connector attaches to
the system board.
– The cable for the PC 350 has three drive
connectors. A fourth, unique connector attaches
to the system board.
The primary diskette drive installed in your computer
(usually known as drive A) must be attached to the
diskette drive connector that is at one end of the
ribbon cable. The unique connector at the opposite
end of this ribbon cable plugs into the system board.
Use the middle connectors as required for additional
diskette or tape drives.
Ÿ Another flat-ribbon signal cable (slightly wider than
the other ribbon cable) connects internal IDE drives.
– This cable has two drive connectors that connect
to IDE drives. A third, unique connector attaches
to the system board.
28
Installing Options in Your Personal Computer
– The connector on the end of the cable that
attaches to the system board might be unique.
If your computer comes with a hard disk drive
installed, one IDE connector on one end of the
flat-ribbon signal cable is attached to the hard disk
drive, and the unique connector on the other end of
the flat-ribbon signal cable is attached to the system
board. You can attach one additional IDE drive to
this cable.
Notes:
1. Ensure that the drive connector at the end of a
flat-ribbon cable is always connected to a device. This
reduces electronic noise emanating from the
computer. Ensure that the other end connector is
connected to the system board. Use the middle
connectors as required for additional devices.
2. One IDE device must be designated as the primary
(master) device and the other as the secondary (slave)
device; otherwise, some of the IDE devices might not
be recognized by the system. The primary/secondary
designation is determined by switch or jumper
settings on each IDE device.
3. To optimize performance when installing more than
two hard disk drives, be sure to attach hard disk
drives with faster data transfer speeds (Mode 1 or
higher) to the primary hard disk drive signal cable
(hard disk drives 0 and 1).
Internal Drives
4. To install more than two IDE hard disk drives, you
must purchase an additional drive signal cable. The
cable must meet the following specifications:
Ÿ Maximum length: 0.46 meters (18 inches)
Ÿ Wire size: 28 AWG
Ÿ Cable capacitive loading: 200 pF maximum
5. If you want to install more than one diskette drive,
you will need to purchase a four-wire Y-cable that
provides two power connectors.
6. To attach an external drive, you need to install an
adapter in the computer.
For help in selecting drives, cables, and other options for
your computer, do one of the following:
Ÿ Within the United States, call 1-800-IBM-2YOU

Ÿ Within Canada, call 1-800-565-3344 or 1-800-465-7999.
