I don't know of a generic way. OpenVortex people did this: http://mail.gnu.org/archive/html/openvortex-dev/2003-10/msg00036.html Obviously the process of finding the proper symbols and using them to intercept hardware access will need custom work. This will only let you trap hardware access as far as you can determine where the code is doing it, i.e. you can't setup a fault to drop you into your own code afaik. -- Ryan Underwood, <[EMAIL PROTECTED]>
