Hi folks,

Been loving FreeBSD for several years now and for some reason never
got hooked up to this group til now.

I just searched google groups for answers to my questions and could
not find anything so away I go ...

I've got an ASUS A7N8X-X mobo which has in the BIOS lots of stats
on CPU temp and fan speeds. In doing some research on how to access
that info from the OS, I came across some buzzwords "lm78", "i2c"
and "smbus". I'm new to smbus, but building kernels and such I've been
doing for over 10 years now.

Anyway, I just cannot seem to find much info on enabling this for
FreeBSD 5.2.1. Checked the docs, the "NOTES" file in the config
dir, and did some websearching and am just not coming up with much.
For FreeBSD 4.9 I found a bit of stuff, and so stuck the following in
my FreeBSD 5.2.1 kernel config file, and built it :

# iicbus
device iicbus
device smbus
device intpm
device alpm
device ichsmb
#device viapm
device amdpm
device smb

It would not compile with viapm so I commented it out. It compiles,
builds and runs. Though to be honest I have no idea what most of those
lines mean because i just can't find info out there. In any case still no valid
smbus info in FreeBSD. I have tried several programs from /usr/ports
like lmmon and healthd. No luck. CPU temp of 255C
and no fans showing up.

How do I do this for my system? Where can I find more info? I've been
websearching for a few days now with no luck.

thanks,
-Alan
