|
||||
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.
