I've been researching dual PII boards and have arrived at a quandry about environmental monitoring. Ideally I would like to be able to remotely query server machines to check for fan failures and overheating. At home where I have 7200rpm disks, no air conditioning and summer temperatures that often approach 40C, operating temperatures are a concern. Tyan and ASUS use the National Semiconductor LM78 for monitoring internal temperature, fan speed, etc. There is Linux support for reading this information and an ostensibly complete data sheet available from national at http://www.national.com/ds/LM/LM78.pdf. Likewise, the Intel DK440LX uses the LM79 - data sheet also available. Gigabyte has their own ACOPS technology which they claim is "supported" by all operating systems in that (the bios?) can sense (purportedly more reliably than LM78 based systems) CPU overheating conditions and "auto speed down" the system. Also, the chassis speaker sounds an audible alarm. http://www.giga-byte.com/RACOPS2.html Gigabyte MB's are cost effective and have a good reputation from people on this list; however, it would appear that contrary to their marketing rhetoric ACOPS is a closed-door solution that is a win only for MS$ users who can realize the unmitigatably overwhelming benefits of Gigabyte's bundled patented SIV application. Comments? Technical references from Gigabyte to match National's open, pro free software approach? I can't find them. -Chris To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
