Thanks.  I was thrown off by the "No HWM available on it!!" line and
the inability to detect a DeviceID.  Apparently my motherboard has
a somewhat unusual arrangement of an VIA 8233 and the non-VIA 
IT8705F probes (which are only supported through ISA apparently).  

Strangely, probes 1 and 3 work, but 2 doesn't (since I only know of
two probes on this motherboard--the one under the CPU and the one
on the end of the cable) I'm surprised the motherboard uses the 
third instead of the second hardware monitor slot.  

<escaflowne/p5> (14 ~): mbmon
Temp.= 24.0, 201.0, 58.0; Rot.= 4891,    0,    0
 Vcore = 1.79, 2.53; Volt. = 3.33, 4.76, 11.67,  -3.00, -1.66

I do wish the program was a little clearer as to what constitutes
"good" numbers for the voltages. :/
