 ==== Installation and Management ====
-==== Problems ====
+== Why so many modules, and how do I cope with them? ==
+We tried to make this package as modular as possible. This makes it easy to add new drivers, and unused drivers will take no precious kernel space. On the other hand, it can be a bit confusing at first.
+Here are two simple guidelines:
+  * Run sensors-detect and do what it tells you.
+  * Always use modprobe, not insmod.
+== How do I know which chips I own? ==
+We have an excellent program that scans all your hardware. It is called sensors-detect and is part of the lm-sensors package, available with all major distributions. Just execute this script, and it will tell you.
+Chip detection in the drivers is fairly good. That means that it is usually harmless to insert more chip drivers than you need. However, this can still lead to problems, so we do not recommend it.
+If sensors-detect didn't find any sensors, either you don't have any, or the ones you have, we don't support. (Look at your motherboard for candidates, then see Help)
+== What chips are on motherboard XYZ? ==
+We have no idea. Here is what you should do:
+  * Run sensors-detect. If that doesn't work read on:
+  * Look at your motherboard.
+  * Check the manufacturer's website or ask their support
+  * Check the Motherboard Monitor website and the "links" page on our website some good cross-references.
+== Do you support motherboard XYZ? ==
+We don't support boards, we support chips. See What chips are on motherboard XYZ.
+== Do you support chip XYZ? ==
+== Anybody working on a driver for chip XYZ? ==
+Please see [[device_support_status|Supported Devices]].
+== Which modules should I insert? ==
+sensors-detect will tell you. Take the modprobe lines it recommends and paste them into the appropriate /etc/rc.d/xxxx file to be executed at startup.
+You need one module for each sensor chip and bus adapter you own; if there are sensor chips on the ISA bus, you also need i2c-isa.o. for each type of chip you own. That's all. On my computer, I could use the following lines:
+<code>
+modprobe i2c-isa
+modprobe i2c-piix4
+modprobe lm78
+modprobe lm75
+modprobe i2c-dev
+sensors -s
+</code>
+== Help, I do not have smbus-arp! ==
+You don't need it. This driver has not much use except for testing SMBus 2.0 ARP and PEC support in the i2c layer.
+== Do I need the configuration file /etc/sensors3.conf? ==
+Yes, for any applications that use libsensors, including the sensors application included in our package. It tells libsensors how to translate the values the chip measures to real-world values. This is especially important for voltage inputs. The default configuration file should usually do the trick. It is automatically installed as /etc/sensors.conf, but it will not overwrite any existing file with that name.
+== The labels for the voltage and temperature readings in sensors are incorrect! ==
+Every motherboard is different. You can customize the labels in the file /etc/sensors3.conf. That's why it exists! The default labeling (in lib/chips.c and /etc/sensors3.conf) is just a template.
+== The min and max for the readings in sensors are incorrect! ==
+You can customize them in the file /etc/sensors3.conf. See above.
+== The min and max settings in /etc/sensors3.conf didn't take effect! ==
+You forgot to run sensors -s. See above.
+== One sensor isn't hooked up on my board! ==
+Use an ignore line in /etc/sensors3.conf so it isn't displayed in sensors.
+== I need help with sensors.conf! ==
+There is detailed help at the top of that file.
+== Do you have a database of sensors.conf entries for specific boards? ==
+No. Good idea though. If you would like to set one up on your website send us mail and we will set up a link to it.
