Hi Mark,

I don't think I agree with this statement. There are not dozens of ways
to measure a voltage. The chip must have an ADC. The table in Hans'
driver (derived from the .ini file provided by Abit) suggests a 10 mV
LSB. Assuming an 8-bit ADC, this means a range from 0 to 2.55V, and the
other scaling factors seem to confirm this (*3 for 5V, *6 for 12V.) If
we know which chip Abit is using (still a W83L950D as for the previous
µGurus?) we might even be able to verify this.
