[lmsensors] package allows you to check some vital statistics of your motherboard

LM Sensors are very dependent on your:
-* kernel
+* [Kernel]
* motherboard (both chipset and manafacturer)
-* distro
+* [Distribution|Category:Distribution]
This will require you to do nasty things to your machine, such as compile kernels, and possibly require you to get out a screwdriver to open up your machine to look at chips on the motherboard ! Not for the faint hearted !
I'm going to go over how I got it going on my motherboard, my kernel, and with Debian Woody. Add your experiances if they are different.

+with some gigabyte boards (and possibly others), the module load order is important
+7ZM (Socket A) requires that you load the modules in the order

+!!Additional Experiences
+!GA-7VTXE motherboard
+Following the excellent instructions above, I was able to fairly easily set up lm-sensors on my GA-7VTXE+ motherboard (which is very similar to the GA-7VTXH+ in the above section). Summary:
+# build the sensors kernel module (I already had i2c support in my kernel for [TVTunerCards] support)
+# # modprobe i2c-proc i2c-isa it87
+# set up /etc/sensors.conf (see below)
+# # sensors -s (as root, to initialise everything)
+# $ sensors (to get a listing printed out)
+
+I knew to use the it87 module and config from the above notes, but if I didn't, I would have looked at my motherboard's manual, for example, [here|http://www.wlug.org.nz/archive/images/ga7vt.jpg].
+
+The reading for the MB temp was consistent with the bios, but the reading for the CPU temp was way out. After a quick read of the documentation, it is because the default assumption is that the 2nd temperature sensor is a diode. Changing this setting to be a resistor made more realistic values appear. I had to add a line like
+ options it87 temp_type=0x38
+to /etc/modules.conf so that the module uses different calculations. If you really want to know how I derived that option, read /usr/share/doc/lm-sensors/doc/chips/it87.gz (in debian, at least).
+
+Here's a link to my /etc/[sensors.conf] file.
+
+!Abit KT7 motherboard
+On an Abit KT7 motherboard, the chip is a "via686b" - you need to use the "via686a" driver. See the [sensors.conf] file for my setup for this.
