3  Prerequisites
================

The prerequisites for compilation, loading and patch creation of the
sk98lin driver are:

- Any device using the sk98lin kernel module needs to be closed.

- The old sk98lin kernel module needs to be unloaded.
  Per default the installation script will do this automatically
  (if "user mode" installation is selected). 
  If you want to shutdown and unload the old sk98lin kernel module
  manually, run the script in "expert installation" mode.

- Your system has to be equipped with a supported network card. 
  Without a card the full driver functionality cannot be checked.

- The kernel source and kernel version have to be consistent. 
  For instance, it might be, that you run kernel version 2.4.20, but 
  the header files the kernel module will be compiled with refer to 
  kernel version 2.4.21. If you don't have the same kernel version, 
  install the sources and compile a new kernel. It's not possible to 
  mix different kernel versions!



	






4  Preparing the Driver Installation Package
============================================

Before the sk98lin driver installation script can be invoked, the 
installation package needs to be unpacked:

1.  Login as 'root'.
2.  Unpack the driver installation package using the command

    # tar xfvj install-???.tar.bz2
    or
    # bunzip2 -c install-???.tar.bz2 | tar xfv -



	





5  Driver Installation
======================

1. After the driver installation package is unpacked, type the following
   commands to start the sk98lin driver build process:

   # cd DriverInstall
   # ./install.sh

2. Select the driver installation mode (see following subchapters).
3. Wait for the driver build process to finish.
   Depending on the installation mode you selected, the driver is either 
   compiled and installed or a kernel patch is generated.



	





5.1  User Installation Mode
---------------------------

Selecting this installation mode the driver sources shipped
with the install package are compiled and the resulting driver 
module object file is installed to a suitable location (usually somewhere
below directory /lib/modules/...).

No source files of the driver are installed into a kernel directory.
Only the driver module object file and the man page of the driver are 
installed onto your system permanently. 
            
The term "user installation" reflects the fact that the build
process runs automatically without any user interaction. In case
of installation problems, the driver installation script autonomously
tries to solve the problem (if this is possible). 

After compilation has finished, the initial system state and 
configuration is recovered and all (possibly) backed-up system 
files are restored from the initial configuration.

There is a version mismatch between the compiler that was used
to build the current running kernel and the compiler which you
intend to compile the kernel module with. In most of the cases,
this is no problem, but there are cases in which this compiler-
mismatch leads to unexpected system crashes

If you know what you are doing and want to override this
check, you can do so by setting IGNORE_CC_MISMATCH system
variable:
Example: export IGNORE_CC_MISMATCH=1
