Pentium III On-Die Thermal Diode
The Pentium III processor incorporates an on-die diode that may be used to monitor the die temperature (junction temperature). A thermal sensor located on the baseboard, or a stand-alone measurement kit, may monitor the die temperature of the Pentium III processor for thermal management or instrumentation purposes.

Abit so far the first and only board with CPU-core temp. monitoring
For those of you who were not watching the Abit Newsgroup, you missed out on watching one of the great motherboard fixes go down in real time. While I have no way of knowing for certain how many motherboards were affected, all (that I have heard of) of the Abit BX6R2 version 2.02 and a couple of the revision 2.01 boards are missing 2 important components which allow the monitoring of the internal thermal diode found in the PII's, PIII's, and Celerons.
At this point, I do not know why the components - a 30k resistor and a .0033 µf (3300 pico farad) capacitor - were removed by Abit. There have been some reports that the temperatures were not as accurate as Abit had hoped for, so they dropped support for monitoring the internal diode.
It has been suggested that the problem may lie in the BIOS's ability to correctly read the diode. This may be correct, as with the circuit working and the CPU diode monitoring turned on in the BIOS (using Modbin), the temp reads too high (like many of the 3rd party temp reading programs). Note: Using Modbin to add the diode temperature into the BIOS has no effect on whether the temp can be read by third party software. The thermal diode located on the CPU can be read with the W83782D Winbond chip. Abit follows Winbond's schematic and places the resistor and the capacitor as follows: The VREF is the Winbond reference voltage, GNDA is the analog ground, and T2 is the thermistor 2 input on the Winbond chip. The 0603 package size capacitor and resistor in this application have no orientation toward + or - voltage. The component location on the BX6r2 is as follows: complete story
