Strange Request: P5B BIOS Temperature Mod

[maewiotr]

I have an Asus P5B with a problem here that is common to this board and its variants. The CPU temperature reporting is buggy and reports the CPU temperature at far higher than what the actual temperature is. This is confirmed by reasing the tJunction temperature from any application or siply touching the heatsink.

There's a roundabout way if fixing this, and that's to disable TM in the CPU options which is the thermal management. This doesn't fix the problem, but rather prevents the CPU from throttling back because of the erroneous temperature reading.

The downside to this is that now you can't use TM, and also that Asus' fan sensing won't work properly because of the high temp reading.

What I would like is for someone to add a negative value of -40 to what the temperature starts out at in the BIOS.

I'm attaching the BIOS here, it's already got several updates I performed myself (OROM, Microcode, SLIC), if someone could take a look at it, I'd be very appreciative.

Thanks
