Hi There ! Anyone can you help me, please ? My system is a ASUS P4T, P4 1.4GHz, running RH9, with the last stable kernel 2.4.22 (from kernel.org), whith the linux-2.4.22-i2c-2.8.1.patch patch applied and lm_sensors-2.8.1.tar.gz installed. Output of sensors-detect: BIOS vendor (ACPI): ASUS System vendor (DMI): System Manufacturer BIOS version (DMI): ASUS P4T ACPI BIOS Revision 1005 We can start with probing for (PCI) I2C or SMBus adapters. You do not need any special privileges for this. Do you want to probe now? (YES/no): Probing for PCI bus adapters... Use driver `i2c-i801' for device 00:1f.3: Intel 82801BA ICH2 Probe succesfully concluded. I have no problem following the instructions on http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/QUICKSTART, except when I have tried to do: # sensors -s as99127f-i2c-0-2d: Can't access /proc file for writing; Run as root? # Looking at /proc/bus I've noticed that i2c* are 0444 ! # ls -l /proc/bus/i2c* -r--r--r-- 1 root root 0 Nov 2 00:11 /proc/bus/i2c -r--r--r-- 1 root root 0 Nov 2 00:11 /proc/bus/i2c-0 running just sensors, looks like fine (...almost...Why -12V and -5V readings are wrong ?): # sensors as99127f-i2c-0-2d Adapter: SMBus I801 adapter at e800 Algorithm: Non-I2C SMBus adapter VCore 1: +1.70 V (min = +1.58 V, max = +1.92 V) VCore 2: +1.82 V (min = +1.58 V, max = +1.92 V) +3.3V: +3.36 V (min = +2.98 V, max = +3.63 V) +5V: +5.06 V (min = +4.52 V, max = +5.48 V) +12V: +12.16 V (min = +10.83 V, max = +13.15 V) -12V: -2.30 V (min = -15.06 V, max = -12.32 V) -5V: -1.23 V (min = -5.49 V, max = -4.50 V) fan1: 0 RPM (min = 3000 RPM, div = 2) fan2: 0 RPM (min = 3000 RPM, div = 2) fan3: 5037 RPM (min = 3000 RPM, div = 2) temp1: +45?C (limit = +60?C) temp2: +42.0?C (limit = +120?C, hysteresis = +100?C) temp3: +255.4?C (limit = +120?C, hysteresis = +100?C) vid: +1.750 V alarms: beep_enable: Sound alarm enabled eeprom-i2c-0-50 Adapter: SMBus I801 adapter at e800 Algorithm: Non-I2C SMBus adapter eeprom-i2c-0-51 Adapter: SMBus I801 adapter at e800 Algorithm: Non-I2C SMBus adapter eeprom-i2c-0-52 Adapter: SMBus I801 adapter at e800 Algorithm: Non-I2C SMBus adapter eeprom-i2c-0-53 Adapter: SMBus I801 adapter at e800 Algorithm: Non-I2C SMBus adapter Finally the questions: 1) Why the permissions for /proc/bus/i2c* are 0444 ? 2) Why the reading for-12V and -5V are wrong ? How can fix this ? any help will be appreciated. thanks in advance, PS: Sorry any mistakes in my text. English isn't my native language. -- Miguel Angelo Rozsas miguel at rozsas.xx.nom.br
