ISA/EISA expansion cards are invariably fitted with links which provide
selection of base addresses (see Figure 13.33). These links
must
be configured
so that no conflicts occur. This precaution is particularly important when new
or replacement cards are fitted to a system. This is, perhaps, a rather obvious
precaution but it is nevertheless one which is easily forgotten! PCI cards are
usually plug-and-play and therefore there is less risk of links, and DIP switches
being incorrectly set. However, it is still important to check that board settings
are correct for the address range and hardware configuration in which the board
is used. This is even more important where several boards are fitted since default
(factory) settings may be identical.
