Greetings. I just last weekend finally figured out the magic needed to
get i2c working (I could never figure out which algorithm to use; finally
it was revealed to me that I didn't need to pick from that column at all;
the drivers select them if they need them), and got sensors working on
a couple of machines.
Of course, one of the machines promptly proceeded to have a motherboard
failure Tuesday morning. I guess it's been too long since I last
made offering to placate Loki.
Anyway, new motherboard, and new sensors chip. Yes, the BIOS reports
reasonable values. sensors-detect detects the W83627HF-AW chip I
can see on the motherboard (Abit AX8, if anyone cares). But sensors(1)
reports garbage:

But now I'm annoyed. Get data sheet, read data sheet.
Write register-dumper. H'm... Config reggister CR22
(accessed via the 0x23/0x2f port pair) is set to 0xbf.
That means that the hardware monitor is powered down!
Set bit CR22.6 to 1... still not working.
Try the "reset" module option. No change. (The sensors(1) output above
is after all this fiddling about. The +12V and +5V numbers are somewhat
plausible, as the +5VSB might be. I don't remember if they were worse
before I played with the power bit. But I know it can monitor the fans,
and isn't. The Vcore numbers, in particular, are obviosuly wrong.
Here are what the BIOS boot menu reports. Voltages sparated by a slash
were flickering. This is copied off paper, so I didn't write trailing
zeros.

(There were also some enable bits I forgot to copy.)
So those are the answers I *should* get.... what's going on?
Here's my register dumper output. The long vertical range is the
config registers. The high byte is the logical device number (0xff
for "global"). The leading = and - signs are just to help you keep
your place.
Then I dump out the hardware monitor registers via the ports at 0x295
and 0x296. First, all registers in the 0x00..0x7f range, then the
0x50..0x5f range with the 8 possible bank selects. (Yes, I unloaded
the module while doing this!)

As you can see, starting at 0x20 and 0x60, VcoreA, VcoreB, and +3.3Vin
readings are all 0xff = 4.08 V. The VCoreA high limit at 0x2b
is clearly 0xff, so I don't see where the BIOS monitor gets 1.7V.
Is there anything obviosuly misconfigured here?
Thanks!
