Configuring expansion cards

Many expansion cards have a number of configurable options.
These options can include items such as: the interrupt used,
the DMA channel used, where any ROM on the card will
appear in the processor's memory map and which I/O ports
are used to control the card.
How to select options like this varies from card to card and
will be described in documentation supplied with the card.
Remember to check any floppy disks supplied with the card
for README or Help files.
Most ISA cards use jumpers and/or switches to select their
configuration options. If this is the case then the card should
be configured before you install it. A few cards are configured
using a software utility supplied with the card, this can only
be done after the card is installed.
PCI cards are automatically configured by a utility in the BIOS.
A PCI configuration screen is provided in SETUP. This screen
is provided for completeness and it is unlikely that you will
need to use it. A description of the options on the screen is
provided in Chapter 4 "SETUP".
If you are not familiar with the concepts of interrupts, DMA
channels, memory maps and I/O ports the following text
attempts to explain what they are, and how to decide which
option to select.
For the following explanations it should be understood that a
peripheral can be either, a subsystem on the motherboard,
or an expansion card.
