FLI4L is a Linux-based ISDN-, DSL- and Ethernet router, which only needs ONE floppy disk to work. Sufficient hardware would be a 486 PC with 16 MB of RAM.
The boot disk, which is essential for FLI4L, may be generated under Unix, Linux or Windows. You will not need any knowledge of Linux itself to do so - but it大 no fault to have any knowledge about Linux or Unix. Base knowledge about networking, TCP/IP, DNS and routing should be available. If you want to enlarge the functionality of FLI4L with your own development, you will need a working Linux system and additionally knowledge about/of Unix/Linux.
Since version 2.0 FLI4L "officially" supports other boot media than floppy disks. Now it大 possible to install more software packages on the FLI4L router; more than there would have been if only a floppy disk can be used.
Before you begin to create a FLI4L installation for hard disk or compact flash media, you should already have successfully installed a "standard" floppy disk configuration as a base installation.
Most optional software packages (OPT packages) may already be available if only a floppy disk installation had been created. Therefor it may only be necessary to use a hard disk if you want to install the whole software palette, available for FLI4L.

For control/status display of the FLI4L router there is another tool: the client imonc. This program is available fo Windows (windows/imonc.exe) and also for Linux (unix/gtk-imonc).
And now...
Have lots of fun with fli4l!
