Hi,

this package contains the patches needed to Linux get support for ELSA's
2 Mbit WLAN cards, namely the AirLancer MC-2 and the AirLancer MC-2 FR 
(french version with reduced channel range).  It is also usable for the
Siemens 'twin' I-Gate M2.  Note that the WLAN card used by Siemens in the
I-Gate N2 access point uses a different card firmware and is not usable
with this driver!

What you need to get this driver running:

- the source tree of the Linux kernel you are using (usually found under
  /usr/src/linux).  Both kernels versions 2.0.x and 2.2.x should work.

- sources of the PCMCIA package.  This driver has been tested with version 
  3.0.12 and version 3.0.14, but later 3.0 versions should work either.
  
To get this driver compiled, the following steps are required:

- configure and compile the Linux kernel (you might already have done
  this...)

- copy the archive of this driver into the PCMCIA package's root directory

- unpack:

    tar xvf wl24_cs.tar.gz

- apply the necessary patches:

    patch -p0 < patch-wl24_cs

- configure and compile the PCMCIA package:

    Configure; make; make install

At this point, you should have a PCMCIA package installed with support for
the AirLancer MC-2.  See the PCMCIA package's documentation for the remaining
installation, e.g. how to automatically start things at boot-time.

What remains to be said?  To configure the network parameters, of your
WLAN, edit the options for the wl24_cs driver in /etc/pcmcia/config.opts :

--> networkname: the symbolic name of your ESS, equivalent to the WLAN
    domain set in the LANCOM Wireless access point or the AirLancer Windows
    driver.  This is an ASCII string of max. 32 characters.

--> networktype: the type of wireless network you have installed.  There
    are tho types of network:  infrastructure (networktype=0) for workstations
    connected to each other and to a LAN via an access point, and adhoc
    (networktype=1) for a number of workstation interconnected to each other
    without an access point.

--> Channel: the RF channel to be used for communication.  Valid numbers
    range from 1 to 13.  Note that for 'french cards', the card will only
    accept values between 10 and 13!  This setting is only relevant if you
    are using an adhoc network and your system is the first one on the
    ehter; in all other cases, it will accept the channel given by other
    stations or the access point since selection of the WLAN to join is
    solely based on the WLAN domain string!

In case of questions or problems, contact the ELSA support.  Note that
this driver is considered *ALPHA*, i.e. it didn't undergo extensive 
quality assurance tests.  Corrections and comments are welcome!

Happy testing and best regards

 Alfred Arnold, ELSA AG
