+Module Parameters
+-----------------
+
+* uch_config: int Override the BIOS default universal channel (UCH)
+ configuration for channels 1-5.
+ Legal values are in the range of 0-31. Bit 0 maps to
+ UCH1, bit 1 maps to UCH2 and so on. Setting a bit to 1
+ enables the thermal input of that particular UCH and
+ setting a bit to 0 enables the voltage input.
+
+* int_mode: int Override the BIOS default temperature interrupt mode.
+ The only possible value is 0 which forces interrupt
+ mode 0. In this mode, any pending interrupt is cleared
+ when the status register is read but is regenerated as
+ long as the temperature stays above the hysteresis
+ limit.
+
+Be aware that overriding BIOS defaults might cause some unwanted side effects!

All temperature channels except temp2 are external. Temp2 is the VT1211
internal thermal diode and the driver does all the scaling for temp2 and
