Ok but it should be possible to say "intercept" the event of a tap, double tap, drap with appropriate coordinates and do something usefull with them. I'm thinking of something like logitech wheel mouse drivers for OS X. I know they use USB which is fairly more simple than low level firmware stuff but eh! i'm just beginning my investigation;) thank you. Julien On Wednesday, Aug 14, 2002, at 03:55PM, David A.

To my knowledge, you can't add functionality to the trackpad hardware
using drivers. To do that, you would have to add capabilities to the PMY
firmware, AFAIK, a procedure that is undocmented. The problem is if you
screw that firmware up (which is highly likely, since it's undocumented
bytecode), you won't be able to boot your system to undo the damage, and
you'd basically have to replace the main logic board in your laptop....
In other words, it's not a very good idea to try this.
Later,
