LmSensorsDellThreeFifty

lm_sensors configuration for Dell 350 systems.

Load the following modules:

i2c-piix4
adm9240
eeprom

Add to /etc/modules.conf or /etc/modprobe.conf:

alias char-major-89 i2c-dev

And for /etc/sensors.conf:

chip "adm9240-*"

  # Adjust the CPU label and warning temps slightly.
  label temp "CPU Temp"

  # Reported temps always seem about 10 degrees too low, so bump them
  # up.
  compute temp [email protected],@+10

  set temp_over 50
  set temp_hyst 60

  # Set limits for all the voltages.
  set "2.5V_min" 2.5 * 0.8
  set "2.5V_max" 2.5 * 1.2
  set Vccp1_min 1.75 * 0.95
  set Vccp1_max 1.75 * 1.05
  set "3.3V_min" 3.3 * 0.95
  set "3.3V_max" 3.3 * 1.05
  set "5V_min" 5 * 0.95
  set "5V_max" 5 * 1.05
  set "12V_min" 12 * 0.95
  set "12V_max" 12 * 1.05
  set "Vccp2_min" 2.5 * 0.8
  set "Vccp2_max" 2.5 * 1.2

Sample output:

alarms:

eeprom-i2c-0-50
Adapter: SMBus PIIX4 adapter at 0440
Algorithm: Non-I2C SMBus adapter
Memory type:            SDR SDRAM DIMM
Memory size (MB):       256

Note that the cpu temps seem pretty low on this system, hence the somewhat arbitrary bump of +10 degrees. That's probably not exactly the right scaling factor.
