Summary	0001137: System powers off on speedfan startup during SMBus scan
Description	When speedfan starts up without /nosmbscan it causes the system to power off. When run in debug mode, it picks 2 SMBuses and a collection of devices. It can scan the first one ok, all registers but as soon as the second one is scanned at $2E $00 the system powers off.
Steps To Reproduce	Start speedfan with SMBus scanning enabled

alfredo 2008-05-13 22:15 manager ~0003545	Please, send me an email and I will send you a beta specific for your hardware.

alfredo 2008-05-13 22:21 manager ~0003546	By the way: do you know if other, similar, tools find any useful device at address $2E on the SMBus on your motherboard?

alfredo 2008-05-13 23:56 manager ~0003547	Beta sent.

alfredo 2008-05-14 19:31 manager ~0003561	Did you receive the beta?

ateeq 2008-05-15 00:58 reporter ~0003575	Beta received and installed. It doesn't shutdown the PC but is't showing any temperatures or fans either (other than CPU temps). I've just run SEND REPORT and I think it's sent the output to you.

alfredo 2008-05-15 01:03 manager ~0003576	Ok. So, this issue is fixed. How can the hardware monitor chip be reached is still a mistery to me on your motherboard. It looks like DELL used a SMSC chip with a disabled hardware monitor subsystem. I hope to be able to find how to access whatever this motherboard is using.
