Providing ACPI access routines for the onboard system monitoring chip(s) doesn't seem to be widely implemented. I suspect its the complications in writing ACPI code to access SMBus without stomping something else, or touching the wrong device and hanging the system. The Intel systems I work with have IPMI and you can access them that way instead of through ACPI. Looks like the P6DBU predates IPMI so the only access to the health chip is through the chipset. The only machine I have around here that provides thermal information is a HP laptop, and it has other ACPI issues. Otherwise, you can try healthd and related programs that directly access the SMBus. -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
