Linux Kernel Compilation

Note
If you are new to Linux, kernel compilation can be somehow difficult. Invalid kernel configurations can lead to inproper function of your operating system or even no function at all. The kernel should be compiled by experienced Linux users only. So, in case that you are a Linux newbie, please refer to the following readings for further information:

For enabling the Linux kernel to support the "HFC-S PCI" based card, the Linux kernel must be compiled together with the HiSax driver in the following way:

Open a shell and change to the directory containing the Linux source files, e.g.:

cd /usr/src/linux

Enter the Linux kernel configuration with

make menuconfig

Then enter the ISDN subsystem as follows:

Image ISDN Subsystem

Enable the support for "HFC PCI-Bus cards":

Image Passive ISDN Cards

Save the kernel settings and compile the kernel by:

make dep && make clean

make bzImage

make modules && make modules_install

After booting the kernel with a HiSax module including the "HFC-S PCI" support, you can load the HiSax ISDN driver with the following commands:

modprobe isdn

modprobe hisax id=HiSax type=35 protocol=2

When the HiSax module has been successfully loaded and your ISDN card has been detected in your PC, the similar messages will appear in your /var/log/messages log file:

May 2 13:17:45 linux kernel: HiSax: HFC-PCI driver Rev. 1.1.4.1 May 2 13:17:45 linux kernel: HiSax: HFC-PCI card manufacturer: CCD/Billion/Asuscom card name: 2BD0 May 2 13:17:45 linux kernel: HFC-PCI: defined at mem 0xd2863000 fifo 0xc2ab8000(0x2ab8000) IRQ 5 HZ 100 May 2 13:17:45 linux kernel: HFC_PCI: resetting card May 2 13:17:45 linux kernel: HFC 2BDS0 PCI: IRQ 5 count 0 May 2 13:17:45 linux kernel: HFC 2BDS0 PCI: IRQ 5 count 34 May 2 13:17:45 linux kernel: HiSax: DSS1 Rev. 1.1.4.1 May 2 13:17:45 linux kernel: HiSax: 2 channels added May 2 13:17:45 linux kernel: HiSax: MAX_WAITING_CALLS added

The hardware driver is now installed and ready for use. The next steps are to configure the Internet connection of your system by using tools like "isdncontrol" and "imon".

Please refer to the ISDN4Linux-FAQ to figure out, how to do this.
