LmSensorsDellFifteenFifty

lm_sensors configuration for Dell 1550 systems.

Load the following modules (on RedHat or Fedora, add them to /etc/sysconfig/lm_sensors):

i2c-piix4
adm1021
adm9240

Add the following entry to /etc/modules.conf (for 2.4 kernels) or /etc/modprobe.conf (for 2.6 systems):

alias char-major-89 i2c-dev

And use the following /etc/sensors.conf:

chip "lm81-*"

chip "max1617a-*"

label temp           "Board"
label remote_temp    "CPU Temp"

Sample output:

Note that this could be improved a lot with use of ignore and set min/max lines.
