Don't know if that counts as an instant message protocol but I'm on IRC
most of the time (freenode network, #linux-sensors).

I don't think it does, most Winbond chips seem to have that kind of name
extention and it never meant anything (to me at least).

I take good note, for the time we'll have lm_sensors values to compare
with.

Asus wants you to believe it's specific to them, while it's not. This is
a feature of the Winbond chip itself ("Thermal Cruise" as they call it).
Asus gives it a different name for obvious marketing reasons, but no way
this is theirs.

OK... Your chip is stuck with bank 6 selected. Sensors-detect can only
detect Winbond chips on bank 0 (the default). Please do:

isaset 0x295 0x296 0x4e 0

then again:

isadump 0x295 0x296

You may even try sensors-detect and see if the W83627EHF is now found as
an ISA chip as well.

Thanks!
