Installing AirJack

AirJack can be challenging to install if you’re not familiar with the configuration of the PCMCIA subsystem in Linux. The installation process consists of the following steps:

1. Obtain and unpack the latest version of AirJack from the home page.

2. Obtain and unpack the source for the version of the pcmcia-cs package used by your Linux distribution. If this is not installed, obtain the latest version from http://pcmcia-cs.sourceforge.net/.

3. Configure the pcmcia-cs package to match your existing configuration using make config.

4. Edit the AirJack makefile file to point to the pcmcia-cs directory just configured.

5. Run make in the directory as your currently logged-in user.

6. Run make install as the root (administrative) user.

This installs a device driver called airjack_cs.o into the modules directory for your Linux system. This driver isn’t loaded by default for supported cards because the PCMCIA subsystem has to be configured to load the driver for your card. You can do this by creating an airjack.conf file in your PCMCIA configuration directory (commonly /etc/pcmcia) containing the following:

device "airjack_cs"
    class "network" module "airjack_cs"

This registers the airjack_cs.o module as a valid PCMCIA device driver. To configure PCMCIA to load this driver, however, PCMCIA needs to be told to load the AirJack driver rather than other installed Prism 2 drivers.

To configure PCMCIA to load a driver for a specific card, we need to know the card identification, which we can determine ...
