Active Protection System
Linux support is so far not available.
Note that this feature definitely depends on software and there is no hardware or BIOS only way of making it work. A statement from IBM clearifies this: "The APS system will require APS software to be installed on the computer before it activates the harddrive parking . This means it will not work on systems preloaded with Linux."
However, IBM made general (unofficial) statements that they are willing to release the specifications of the hardware sensor and its API to the linux community or some developers, but they in fact, never did. Also some linux developers actively tried to contact with IBM about the issue but were unable to make progress.
|March 2004||Wyrfel||asked IBM representatives at CeBIT 2004 about state of linux support||got promise that specifications will be released, but nothing actually happened|
|May 9th, 2004||Sam Hocevar||Wrote to the IBM France Linux Marketing Program manager about who to contact to get specs||email was forwarded on May 10th to to at least 6 additional IBM people, but no answer so far|
- Quoted from NewScientist.com: The latest Apple PowerBook laptops can be controlled with a gentle shake. Programmer Amit Singh has written code that lets him use the sensor to control software on the computer. The code is published at www.kernelthread.com/software/ams/.
- There is a fairly detailed article about reverse engineering the APS accelerometer interface by Mark Smith from IBM Research. Apparently they even have a prototype Linux driver working, but cannot release the full source yet.
- There is a mailing list dedicated to developing and testing a driver and user space program. More info on this mailinglist and the archive at .
