First edit /etc/capi.conf to match your configuration.

here an example for the AVM B1 PCI card:

    # card   file    proto   io    irq    mem   cardnr  options
    b1pci    b1.t4   DSS1    -     -      -     -

First option is the name of the kernel driver, second is the firmware
file which will be uploaded to the card. All firmware files for active
ISDN controllers have to be placed in /lib/firmware.

The 'cardnr' option can be left '-' if you only have one card.
Otherwise fill in the card number you want to assign to this card.

'options' is a list of options which are passed via 'modprobe' to
the card driver. You can also set them somewhere in /etc/modules.d
but this is only recommended for USB based cards, where capi.conf
is normally not used/needed.

Then you should check /etc/conf.d/capi and change it to your needs.

Now you can start the CAPI with

    /etc/init.d/capi start

It should show the loaded drivers/cards after the initialization.
You can check the CAPI with the 'capiinfo' command.

So, if all runs smoothly, then fixate it

    rc-update add capi boot

You can now install the package net-dialup/isdn4k-utils if you
want to use all the legacy ISDN apps, such as 'isdnlog'.


modules oder static?
~~~~~~~~~~~~~~~~~~~~
In general it's ok to compile all ISDN/CAPI stuff into the kernel.
But I suggest to compile at least all card drivers as a module.
That includes the 'capidrv' driver! That way it's much easier to
change a card and/or unload the driver if needed. 


hotplug or hardwired?
~~~~~~~~~~~~~~~~~~~~~
Gentoo supports hotplug for CAPI-Cards. Just plug in your card,
wait for the beep (if enabled in /etc/conf.d/capi) and check with
'capiinfo' if your card is available to the CAPI subsystem.

If you have more than one card and/or depend on services like
'capi4hylafax' or 'isdnlog', it's better to disable hotplug in
/etc/conf.d/capi and configure your card(s) in /etc/capi.conf.

You can always check what card(s) are loaded with

    /etc/init.d/capi info

If you stopped CAPI with

    /etc/init.d/capi stop

you have to unplug all USB-cards to re-initialize them again.
Ok, reboot is another option. ;-) Using only hotplug, you can
plug in and out your card as often as you want.


pppdcapiplugin
~~~~~~~~~~~~~~
please read the README and have a look at the examples.
You obviously need net-dialup/ppp to make this work.


rcapid
~~~~~~
if you want to use 'rcapid' (remote capi daemon), then install
sys-apps/xinetd and configure it in /etc/xinetd.d/rcapid
and read the rcapid documentation.
