5.7.1 Compiling and Installing the Kernel

When you are finished editing your kernel configuration file, you must prepare your new kernel for installation. First execute the command ``config ISDN4BSD'' where ISDN4BSD is the name of the kernel configuration file we just edited. Running this command must produce no error messages and the final message must be: ``Kernel build directory is ../../compile/ISDN4BSD''.

Now you can compile your new kernel; change your working directory to the just created kernel build directory by executing ``cd ../../compile/ISDN4BSD'' and execute ``make depend''. This step is mandatory because it initializes all dependencies in the source tree. It may take a while until it is finished. After that you are ready to actually compile your new kernel. Execute ``make'' - this may also take a while. After it has finished you are ready to install your kernel by executing ``make install''.

In case you are running FreeBSD >= 5.0, don't forget to update your /boot/device.hints file in case you are using an ISDN card for the ISA bus !

Now you should do a reboot by executing ``shutdown -r now''.
