Our ISDN PCI card IA-128P use either "Winbond 6692"
or "Cologne HFC-S PCI" chipset.

Linux kernel 2.2.13 or later have built-in its driver.
In general, you should recompile the kernel to add its
driver to the kernel.  For example, run "make xconfig" 
in X windows to add its driver then compiles the kernel 
to use.
(Under the ISDN subsystem, enable "Hisax Support for 
Winbond W6692" or "HiSax Support for HFC PCI-Bus cards")

By the way, you can also use command "ismod hisax type=35" 
for HFC-S PCI card or "ismod hisax type=36" for Winbond 
6692 card to insert the hisax driver module.

After the hardware is now installed, and you can go on 
configuring your system to use that hardware.
The best way to figure out how to do this, is the
