If you are ready to take some risk and think getting the third case fan input is worth it, you can try enabling fan4. I say it is a bit more risky because it involves changing the pin configuration. As we don't know what this pin is actually used for and connected to, bad surprises could happen. If you don't feel like doing it, just don't. If you want to try enabling fan4, do the following: # rmmod it87 # isaset -f 0x2e 0x87 # isaset -f 0x2e 0x01 # isaset -f 0x2e 0x55 # isaset -f 0x2e 0x55 # isaset 0x2e 0x2f 0x07 0x07 # isaset 0x2e 0x2f 0x26 0xb8 # isaset 0x2e 0x2f 0x02 0x02 (At this point you may double-check that value of register 0x26 was properly changed, using "isadump -k 0x87,0x01,0x55,0x55 0x2e 0x2f 0x07".) # isaset 0x295 0x296 0x0c 0x37 # modprobe it87 You may or may not get the extra fan speed reading you were looking for. If you don't, then I suggest you restore the original chip configuration, by either cold booting the machine, or going through the following sequence: # rmmod it87 # isaset 0x295 0x296 0x0c 0x07 # isaset -f 0x2e 0x87 # isaset -f 0x2e 0x01 # isaset -f 0x2e 0x55 # isaset -f 0x2e 0x55 # isaset 0x2e 0x2f 0x07 0x07 # isaset 0x2e 0x2f 0x26 0x98 # isaset 0x2e 0x2f 0x02 0x02 # modprobe it87 Good luck :-) -- Jean Delvare http://jdelvare.nerim.net/wishlist.html _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
