2.1.6 PCCARD Support
On many modern hosts, PCCARD devices can be configured to route their
interrupts via either the ISA or PCI interrupt paths. The pcic(4)
<http://www.FreeBSD.org/cgi/man.cgi?query=pcic&sektion=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 /boot/loader.conf, may fix the
problem:
 hw.pcic.intr_path="1"
    hw.pcic.irq="0"
When installing FreeBSD on such a system, typing the following lines to the
boot loader may be helpful in starting up FreeBSD for the first time:
 ok set hw.pcic.intr_path="1"
ok set hw.pcic.irq="0"


PCCARD ejection can sometimes result in a hang; a workaround for these cases
is to perform a:
 # pccardc power 0 slot
