Hardware Monitoring?

[Cyberkiller6]

I have an Asus P2B with latest bios, I have a p2 333mhz and a p3 500mhz, I cannot get the cpu temperature for either of them. In the BIOS it says N/A and PC Probe says N/A. The mothboard supports hardware monitoring, I can get the mobo temp but not the cpu temp. Any ideas on howto fix this?

Thanks,

got it working using an external diode, but its readnig anywhere from 70-78 degrees celsius on my p3 500. Seems a bit high to me. I am using latest version of pc-probe.
