You need to have i2c and lm_sensors installed before running this program. Also, you need to be `root', or at least have access to the /dev/i2c-* files, for most things. If you have patched your kernel and have some drivers built in, you can safely answer NO if asked to load some modules. In this case, things may seem a bit confusing, but they will still work. It is generally safe and recommended to accept the default answers to all questions, unless you know what you're doing. IF THIS IS AN IBM THINKPAD, PRESS CTRL-C NOW! IBM Thinkpads have a severely broken i2c/SMBus implementation, just scanning the bus will break your Thinkpad forever! If this is a non-Thinkpad IBM, we still suggest you press CTRL+C. We have had users reporting system breakage on other IBM systems as well. 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 `rivatv' for device 02:00.0: GeForce FX 5600 Use driver `i2c-nforce2' for device 00:01.1: nVidia Corporation nForce2 SMBus (MCP) Probe succesfully concluded. We will now try to load each adapter module in turn. Load `rivatv' (say NO if built into your kernel)? (YES/no): FATAL: Module rivatv not found. Loading failed... skipping. ** Note: rivatv module is available at http://rivatv.sourceforge.net/ Load `i2c-nforce2' (say NO if built into your kernel)? (YES/no): FATAL: Module i2c_nforce2 not found. Loading failed... skipping. If you have undetectable or unsupported adapters, you can have them scanned by manually loading the modules before running this script. To continue, we need module `i2c-dev' to be loaded. If it is built-in into your kernel, you can safely skip this. i2c-dev is not loaded. Do you want to load it now? (YES/no): Module loaded succesfully. We are now going to do the adapter probings. Some adapters may hang halfway through; we can't really help that. Also, some chips will be double detected; we choose the one with the highest confidence value in that case. If you found that the adapter hung after probing a certain address, you can specify that address to remain unprobed. That often includes address 0x69 (clock chip). Some chips are also accessible through the ISA bus. ISA probes are typically a bit more dangerous, as we have to write to I/O ports to do this. This is usually safe though. Do you want to scan the ISA bus? (YES/no): Probing for `National Semiconductor LM78' Trying address 0x0290... Failed! Probing for `National Semiconductor LM78-J' Trying address 0x0290... Failed! Probing for `National Semiconductor LM79' Trying address 0x0290... Failed! Probing for `Winbond W83781D' Trying address 0x0290... Failed! Probing for `Winbond W83782D' Trying address 0x0290...

Probing for `IPMI BMC KCS' Trying address 0x0ca0... Failed! Probing for `IPMI BMC SMIC' Trying address 0x0ca8... Failed! Some Super I/O chips may also contain sensors. Super I/O probes are typically a bit more dangerous, as we have to write to I/O ports to do this. This is usually safe though. Do you want to scan for Super I/O sensors? (YES/no): Probing for `ITE 8702F Super IO Sensors' Failed! (skipping family) Probing for `Nat. Semi. PC87351 Super IO Fan Sensors' Failed!

(0x52) Probing for `Winbond W83L517D Super IO' Failed! (0x52) Now follows a summary of the probes I have just done. Just press ENTER to continue: Driver `w83781d' (may not be inserted): Misdetects: * ISA bus address 0x0290 (Busdriver `i2c-isa') Chip `Winbond W83627HF' (confidence: 8) Driver `w83627hf' (should be inserted): Detects correctly: * ISA bus address 0x0290 (Busdriver `i2c-isa') Chip `Winbond W83627HF Super IO Sensors' (confidence: 9) I will now generate the commands needed to load the I2C modules. Sometimes, a chip is available both through the ISA bus and an I2C bus. ISA bus access is faster, but you need to load an additional driver module for it. If you have the choice, do you want to use the ISA bus or the I2C/SMBus (ISA/smbus)? To make the sensors modules behave correctly, add these lines to /etc/modules.conf: #----cut here---- # I2C module options alias char-major-89 i2c-dev #----cut here---- To load everything that is needed, add this to some /etc/rc* file: #----cut here---- # I2C adapter drivers modprobe i2c-isa # I2C chip drivers modprobe w83627hf # sleep 2 # optional /usr/local/bin/sensors -s # recommended #----cut here---- WARNING! If you have some things built into your kernel, the list above will contain too many modules. Skip the appropriate ones! You really should try these commands right now to make sure everything is working properly. Monitoring programs won't work until it's done. Do you want to generate /etc/sysconfig/lm_sensors? (YES/no): no --- 2. --- [root at mrsuicide mrsuicide]# isadump 0x295 0x296 WARNING! Running this program can cause system crashes, data loss and worse!
