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.

Cant see ACPI thermal zones on a Supermicro P6DBU

[David P. Reese Jr.]

Does anyone know a reason why i should not see any info about the thermal
zones on a Supermicro P6DBU in sysctl?  I'm not even seeing the acpi_tz's
in dmesg.  As far as i know, the board does have thermal sensors.  I can
check the cpu temperatures in bios.  If it would help, i could also provide
the output of acpidump.
