Configuring the card

EXPANSION CARDS

If, having read the following installation instructions, you do not
feel confident about installing expansion cards yourself you may
wish your supplier or service organisation to fit the card for you.
The only tool required is a small cross-head screwdriver.
Warning
Warning
Never carry out any work on the equipment with power applied. Always
switch off at the supply and remove the power lead from the equipment
before starting work.
The documentation accompanying the card should tell you what is
required. Remember to check any diskettes supplied with the card
for README or other help files, before you start. If you are in any
doubt consult the supplier or manufacturer.
If manual configuration is required, usually with 'Industry Standard
Architecture' (ISA) cards, then you will probably need to specify at
least two of the following:
Interrupt request level (IRQ)
Direct memory access (DMA) channel
Base input/output (I/O) port address
Base memory address
The important thing to understand is that the settings used by the
card must be different from the settings used by the other hardware
in the computer, whether another card or a component on the
motherboard, the settings must not conflict.
Some settings are done by jumpers and/or switches on the card and
are best done before installation, others are configured by running
installation software after installation. Some cards use a mixture of
both methods. Cards often come with pre-configured or default
settings. It is best to rely on these settings as much as possible, and
change them only if they conflict with other devices.
