If the chosen option is successful, write it to the variable PCMCIA_CORE_-

OPTS in /etc/sysconfig/pcmcia to use it permanently:

PCMCIA_CORE_OPTS="do_apm=0"

Checking free I/O areas may lead to problems if other hardware compo-

nents are disturbed by this. Avoid this by using probe_io=0.

If several options should be used, separate them by spaces:

PCMCIA_CORE_OPTS="do_apm=0 probe_io=0"

If errors occur while loading the i82365 module, refer to the manual page

of i82365. A problem in this context is a resource conﬂict — if an inter-

rupt, I/O port, or memory area is occupied twice. Although the module

i82365 checks these resources before they are made available to a card,

sometimes just this check leads to problems. Checking the interrupt 12

(PS/2 devices) on some computers leads to the mouse or keyboard hang-

ing. In this case, the parameter irq_list=<List of IRQs> can help.

The list should contain all IRQs to use. For example, enter the command

modprobe i82365 irq_list=5,7,9,10 or permanently add the list of

IRQs to /etc/sysconfig/pcmcia:

PCMCIA_PCIC_OPTS="irq_list=5,7,9,10"

In addition, there are /etc/pcmcia/config and /etc/pcmcia/

config.opts. These ﬁles are evaluated by card manager. The settings

made in them are only relevant when loading the driver modules for the

PCMCIA cards. In /etc/pcmcia/config.opts, IRQs, I/O ports, and

memory areas can be included or excluded. The difference from the option

irqlist is that the resources excluded in config.opts are not used for a

PCMCIA card, but are still checked by the base module i82365.

Improperly Functioning or Nonfunctioning PCMCIA Card

Here, there are basically three variations: the card is not detected, the driver

cannot be loaded, or the interface made available by the driver is set up

incorrectly. Determine whether the card is managed by the card manager

or hotplug. For external PCMCIA, card manager always takes control. For

kernel PCMCIA, card manager manages PC card cards and hotplug man-

ages CardBUS cards. Here, only card manager is discussed.
