Yes, I realized it after sending, missing Reply-To-Header. So I
resent it to the list, too.

VRM9.1 lists 1.850V so VID inputs read 0.

I do have an voltmeter, but I am not going to measure, since it
really am afraid of killing the cpu of a short.

Your computing line is working:
Adapter: ISA adapter
+3.3V: +3.30 V (min = +3.14 V, max = +3.47 V)
+2.5V: +2.38 V (min = +2.38 V, max = +2.63 V) ALARM
VCore: +1.40 V (min = +1.35 V, max = +1.44 V)
+5V: +4.66 V (min = +4.51 V, max = +5.49 V)
+12V: +11.49 V (min = +10.77 V, max = +13.21 V)
+3.3V: +3.28 V (min = +3.13 V, max = +3.46 V)
Case Fan: 0 RPM (min = 3006 RPM, div = 2)
CPU Fan: 0 RPM (min = 3006 RPM, div = 2)
CPU Temp: +45.4 °C (high = +85 °C, hyst = +79 °C)
Int Temp: +61.0 °C (high = +65 °C, hyst = +60 °C)
vid: +1.250 V (VRM Version 8.5)
Now other voltages are computed correctly.
Well, the values still might need some adjustments, since I can't
believe, that 2.5V is 2.38 and 12V is 11.49. What do you think about it?
