Chapter 1 Hardware Configuration 7
Safety precautions
Follow these simple precautions to protect yourself from harm and
your PC from damage.
1. To avoid electric shock always disconnect the power from your PC
chassis before you work on it. Don’t touch any components of the
CPU card or other cards while the PC is on.
2. Disconnect power before making any configuration changes. The
sudden rush of power as you connect a jumper or install a card may
damage sensitive electronic components.
3. Always ground yourself to remove any static charge before you
touch your CPU card. Be particularly careful not to touch the chip
connectors. Modern integrated electronic devices, especially CPUs
and memory chips, are extremely sensitive to static electric
discharges and fields. Keep the card in its anti-static packaging
when it is not installed in the PC and place it on a static dissipative
mat when you are working on it. Wear a grounding wrist strap for
continuous protection.
Jumper settings
This section tells how to set the jumpers to configure your card. It
gives the card default configuration and your options for each jumper.
After you set the jumpers and install the card, you will also need to run
the BIOS Setup program (discussed in Chapter 5) to configure the
serial port addresses, floppy/hard disk drive types and system operat-
ing parameters. Connections, such as hard-disk cables, appear in
Chapter 3.
Card default settings
We set the card’s jumpers at the factory for the most popular configu-
ration. If this configuration matches your needs, you may not need to
change the jumpers at all. The default configuration is as follows:
• CPU clock: 33 MHz. (J2, J3, J4, J5)
• Color display is attached (J6)
