<para>On many modern hosts, PCCARD devices can be configured to
route their interrupts via either the ISA or PCI interrupt paths.
The &man.pcic.4; driver has been updated to support both interrupt
paths (formerly, only routing via ISA was supported). In most
cases, configuration of PCMCIA devices in laptops is simpler and
more flexible. In addition, various Cardbus bridge PCI cards
(such as those used by Orinoco PCI NICs) are now supported. Some
hosts may experience problems, such as hangs or panics, with PCI
interrupt routing; they can frequently be made to work by forcing
the older-style ISA interrupt routing. The following lines,
placed in <filename>/boot/loader.conf</filename> or typed to the
boot loader may fix the problem. &merged;</para>
