News: A new linux driver has been released with support for the linux 2.6 kernel: apanel-linux-1.3. You can find it at the download page.

The notebook Fujitsu C-4110 lifebook has an application panel (if you want to know what it is, look at Fujitsu C-4110 description). This works in windows, but what if you want to use it from another operating system? Since Fujitsu wasn't very helpful in this respect, I had to find it out myself.

I found out some i/o sequences that could be implemented in drivers for other platforms. After some time, I found out that the i/o sequences looked a lot like smbus commands and after trying it out on my laptop, I rewrote the technical details and wrote a new driver which should support most models. After that I found specs for some of the ic's that are used. They also tell how the driver could be made interrupt-driven. But that still has to be done (a pre-alpha test version works!).

Go to the download page to download the drivers. Currently, FreeBSD and linux are supported. Of course it's all open-source.

I want to thank Martijn Coenen en Leon Schrijvers for their TLP Project with which it all started, and Jochen Eisinger for writing the linux driver.
