    In order to use this FRITZ!Card driver, a couple of kernel modules are required: 
    capi.o, capiutils.o, kernelcapi.o and capifs.o. The source code for these modules 
    is part of the linux kernel in directory /usr/src/linux/drivers/isdn/avmb1 and 
    will be compiled with the kernel if the following settings are found in the 
    kernel configuration:

        CONFIG_EXPERIMENTAL=y

        CONFIG_ISDN_CAPI=m
        CONFIG_ISDN_DRV_AVMB1_VERBOSE_REASON=y
        CONFIG_ISDN_CAPI_MIDDLEWARE=y
        CONFIG_ISDN_CAPI_CAPI20=m
        CONFIG_ISDN_CAPI_CAPIFS_BOOL=y
        CONFIG_ISDN_CAPI_CAPIFS=m
        CONFIG_ISDN_CAPI_CAPIDRV=m

    For "make menuconfig" go to "ISDN subsystem", "Active cards" and select:

        ...
        <M> CAPI2.0 support
            [*]   Verbose reason code reporting (kernel size +=7K)
            [*]   CAPI2.0 Middleware support (EXPERIMENTAL)
            <M>   CAPI2.0 /dev/capi support 
            [*]     CAPI2.0 filesystem support
            <M>   CAPI2.0 capidrv interface support
        ...

    In addtion to these entries, please enable entry "Prompt for development 
    and/or incomplete code/drivers" in the very first menu named "Code maturity 
    level options".

    After the kernel's compilation, all CAPI modules can be found in directory 
    /lib/modules/`uname -r`/kernel/drivers/isdn/avmb1/
