Your computer can accept two basic types of
expansion card:
♦
ISA or Industry Standard Architecture cards
♦
PCI or Peripheral Component Interconnect
cards
You don’t need to understand what these terms mean,
but before adding a card to your computer you will
need to know whether it is ISA or PCI and possibly
its physical dimensions.
Configuring the card
Part of the installation procedure for an expansion
card involves setting up or “configuring” the card so it
will work correctly in the computer.
Most modern PCI cards employ a feature called “Plug
and Play” (PnP). This allows Windows 95 – and
other PnP-aware operating systems – to configure the
card automatically the first time you turn on the
computer after installing the card.
However, many ISA cards (and some PCI cards)
require manual configuration. If manual configuration
is required, 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
of the card you are installing must not conflict with
the settings used by other cards already in the
computer or by components on the computer’s
motherboard.
The documentation accompanying the card should
tell you whether the card supports Plug and Play, or if
not, how to configure it. Remember to check any
diskettes supplied with the card for README or
other help files.
Some cards require you to move jumpers or set
switches on the card to configure them. This is best
