Also, for Tyan boards which contain both a -Super I/O chip and a second i2c-only Winbond chip (often a W83782D), -using this driver will avoid i2c address conflicts and complex -initialization that were required in the w83781d driver. - -If you really want i2c accesses for these Super I/O chips, -use the w83781d driver. However this is not the preferred method -now that this ISA driver has been developed. - -The w83627_HF_ uses pins 110-106 as VID0-VID4. The w83627_THF_ uses the -same pins as GPIO[0:4]. Technically, the w83627_THF_ does not support a -VID reading. However the two chips have the identical 128 pin package. So, -it is possible or even likely for a w83627thf to have the VID signals routed -to these pins despite their not being labeled for that purpose. Therefore, -the w83627thf driver interprets these as VID. If the VID on your board -doesn't work, first see doc/vid in the lm_sensors package[1]. If that still -doesn't help, you may just ignore the bogus VID reading with no harm done. - -For further information on this driver see the w83781d driver documentation. - -[1] http://www.lm-sensors.org/browser/lm-sensors/trunk/doc/vid - -Forcing the address -------------------- - -The driver used to have a module parameter named force_addr, which could -be used to force the base I/O address of the hardware monitoring block. -This was meant as a workaround for mainboards with a broken BIOS. This -module parameter is gone for technical reasons. If you need this feature, -you can obtain the same result by using the isaset tool (part of -lm-sensors) before loading the driver: - -# Enter the Super I/O config space -isaset -y -f 0x2e 0x87 -isaset -y -f 0x2e 0x87 - -# Select the hwmon logical device -isaset -y 0x2e 0x2f 0x07 0x0b - -# Set the base I/O address (to 0x290 in this example) -isaset -y 0x2e 0x2f 0x60 0x02 -isaset -y 0x2e 0x2f 0x61 0x90 - -# Exit the Super-I/O config space -isaset -y -f 0x2e 0xaa - -The above sequence assumes a Super-I/O config space at 0x2e/0x2f, but -0x4e/0x4f is also possible. - -Voltage pin mapping -------------------- - -Here is a summary of the voltage pin mapping for the W83627THF.
