Which just means nothing for the CPUs ;) The chipset rarely matters (I've yet to encounter any PC chipset that natively handles full fan, voltage, and temperature monitoring), but the motherboard model can tell me a lot. :-) Boards have to include an external H/W monitoring IC (such as one from National Semiconductor (LMxx), AMD, or Winbond), have thermistors placed around the board, and have the H/W IC tied into the ISA or SMBus. Sometimes the H/W monitoring IC also acts as a super I/O chip (which means it handles serial, parallel, keyboard, mouse, and floppy disks -- and sometimes IDE). I can't find anything on Intel's site that clues me in; all the PDFs are vague as far as what chips are on the board. I tried searching for a high-resolution photo of the L440GX on Google Images, but I find none which are sharp/clear enough. The best I could find was this: http://bbs.yjfy.com/UploadFile/2008-2/20082818545062073.jpg I see Intel northbridge and southbridges, a Cirrus Logic (VGA?) chip, an Intel flash chip (probably for CMOS), and an Intel NIC. Four chips I don't recognise are an Intel chip on the far right, a mystery chip at the bottom of the board (can't make out company logo), and two chips with "E" in their company logo (right of PCI slots). Possibly one of these handles H/W monitoring. If you can reboot the system and go into the BIOS, see if you can find anything that looks remotely like CPU and system temperatures, as well as voltages. If there's no such menu, the board likely has no support for such. P.S. -- You're the 2nd person I've encountered in under a week who's using 440BX/GX-based hardware in present day. I would not be surprised if the board is simply going bad/failing due to age. :-) -- | 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.
