Jetway NF93, lm-sensors, Fintek f71882fg

Post by csavery » Thu May 06, 2010 2:43 am

Hello,

I've just setup my Jetway NF93 with Ubuntu. I'm not getting proper info from lm-sensors and looking for help from anyone who has this working successfully.

Running sensors-detect does find coretemp and the Fintek f71882fg. The coretemp sensor is giving good readings for the CPUs. But I get nothing sensible from the other device. I'm now on the new Ubuntu 10.4 server install and apparently this Fintek device is now supported but seems to be either defective or incomplete. The sensors3.conf file has some lines for it but only for a few voltage signals and no temp or fans and these lines do not affect sensor output anyway. I expect something is wrong here, either with detected chip or how it talks to chip on this board.

I'm hoping someone out there has this board and managed to get proper sensors support, and actually I'd be grateful for any other tips about this board with Linux. Help, please...

My NC81 with Fintek f71862fg needs 2 things:

1) add acpi_enforce_resources=lax to boot command line to allow sensors modules to conflict with ACPI addresses - I suspect this is your basic issue. It sounds counter intuitive but until there are ACPI drivers for the sensors modules is necessary.

2) My modified sensors3.conf (I started by copying 1 from somewhere on the web - should have credit for wherever I got the base version but ...!)

Code: Select all

# Jetway NC81-LF

chip "f71862fg-*"

# in5=VCore identified by watching changes consequent to CnQ
# in6=NBVCC identified by watching changes consequent to BIOS changes
# in4=VDIMM identified by watching changes consequent to BIOS changes
# in0, in7 and in8 are apparently hordwired in the chip
# A guess that in1=5V and in3=5VSB on their raw value being equal
# A guess that in2=12V
# Concerned that BIOS screen shows VLDT but nowhere in my guesses!

    label in0 " 3.3V"
    label in1 "  +5V"
    label in2 " +12V"

Thank you for that info. It made a difference as now sensors shows values for fan, temp and some voltages. I wonder how close the match is between your Fintek and the one on this NF93? The voltages are wrong but I haven't tried adding in your conf changes yet.

The device shows up as f71858fg-isa-0290 in the output now. Not what I expected but at least there's some values.

It seems my MB is quite hot, more than I expected, 66C - if that value is to be trusted. I have high ambient temp here (Thailand 37C right now) so it's hard to keep things cool. I'll be adding a case fan running at 5V to help even though it supposedly should run without fan.

Thanks again!
