Subject: Intel D845GEBV2 with lm85: config is locked
Date: Thu, 19 May 2005 06:24:20 +0000 [thread overview]
Message-ID: <000501c38918$5f227520$fe0aa8c0@freeman> (raw)
Hello,
I've got an Intel mainboard D845GEBV2 as replacement for my Asus P4B-266SE
(that ASB100 mess). I've mounted it, gone through the configs and
sensors-detect said I should use the lm85 driver. With lm85 it seem to work
well, except I cannot change anything in the proc interface. The values
reported seem correct but all changes (e.g. echoing values to the pwm#
registers) are ignored... As far as I can see from the BIOS, that board has
settings for fan control and speed. I guess that the BIOS initializes the
sensors during POST but as far as I could see, there was no change to the
problem even I deactivate the settings from the BIOS. I've took a look at
the board and found following devices I could think of being attached to the
bus: LM 85 BIMQ, ICS 950227 AF, FW 82801 DB, PC 87382 IBU/VLA and the eeprom
from the RAM. Intel claims there is an SMSC LPC47M172 on board. Here is the
output of what I could get from my system.

I had to do a cold reset after the use of i2cdetect/dump. I tried to exclude
all except 0x2e but without success.
Do you have an idea how to solve that problem?
