Chris, I contacted SMSC but they won't give out the datasheets since those are DELL specific components and I'm an HP person :-) The only other thing I can suggest is to take register dumps (i2cdump) when the machine is idle and when the CPU is busy and the fans spinning (faster). Then we can take a look at what register values changed and compare it with currently supported chips to find a possible compatible match. ...juerg On Mon, Jun 30, 2008 at 2:43 PM, Chris Friedline <chris at friedline.net> wrote: > Juerg, > > Unfortunately, I can't do Windows on this box at this time.
