use the w83781d driver. However this is not the preferred method

now that this ISA driver has been developed.



Technically, the w83627thf does not support a VID reading. However, it's

possible or even likely that your mainboard maker has routed these signals

to a specific set of general purpose IO pins (the Asus P4C800-E is one such

board). The w83627thf driver now interprets these as VID. If the VID on

your board doesn't work, first see doc/vid in the lm_sensors package. If

that still doesn't help, email us at lm-sensors@lm-sensors.org.

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.
