In the device tree I've found the via-pmu, and under this is a node called 'power-mgt'. A property of this is called 'thermal-info'. As far as I know this must be related to the temp sensor in the Pismo because the G4 chip I have in it doesn't have the thermal assist temp diode on the chip enabled. To check that this was specific to the Pismo I found the same 'power-mgt' property on a Digital Audio G4, which had everything listed the same, apart from the 'thermal-info', which was missing. I've now hit a problem. There are 4 values of data encoded in open firmware for the 'thermal-info'. I believe they are the limits for the fan, as they do not change from boot up o when the computer is definitely toasty. I can write one value by using the following command: [code]12345678 encode-int " thermal-info" property[/code] However, I need to be able to write all 4 values - and I don't know the open firmware commands to do this... could anyone help? Thanks (and sorry for the rambling post), James. _______________________________________________ Do not post admin requests to the list. They will be ignored.
