SMBus is there, now what? (fan speed problem)

[Olivier Drouin]

Hello Guys

 

I tried this thread without much success on the freebsd-acpi mail list: 

http://lists.freebsd.org/pipermail/freebsd-acpi/2007-November/004229.html

Anyway, I don’t think the problem is related to Acpi now.

 

I read this:

HYPERLINK
"http://www.freebsd.org/releases/6.2R/hardware-i386.html"http://www.freebsd.
org/releases/6.2R/hardware-i386.html

 

Here is the board/chassis I’m using: 

HYPERLINK
"http://www.intel.com/design/servers/boards/se7230nh1-e/index.htm"http://www
.intel.com/design/servers/boards/se7230nh1-e/index.htm

 

I rebuilt a kernel with the following new devices:

device intpm

device ichsmb

device smbus

device intpm

device iic

device iicbus

device iicbb

device intpm

device smb

 

I assume its way too many but I don’t even know which does what.

 Anyway with this setup I can see /dev/smb0.

Here is the output of some of the utilities:
