There's a web page mentioning this board (note: entirely Japanese) -- http://iktaka.dyndns.org/node/11 The bottom part of the page states that Linux's lm_sensors 3.0.2 can successfully monitor temperatures, voltages, and fan RPMs on that board, very likely via SMBus. Ideally I should be able to track down technical details by looking at that code. I'd feel much more comfortable asking Intel and having them provide necessary registers and offsets, though; I prefer to avoid reverse-engineering things if possible (less mistakes). -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
