Two options: If you can derive from the documentation of your Acer laotop if it is _compatible_ to one of the implementations provided by the system, use that instead. You can do "trial & error" to see if one of the modules works, even though the name is different. In worst case, load them all (by using * wildcard) and check with "kldstat". -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
