VCore settings for Digital PC 3010

I am looking in upgrading PentiumMMX CPU to an AMD K6-2/3 series processor.
The documention only list the following settings: 3.5, 2.8, 2.9, 3.2, and
2.1v.
This is configured with 5 dip switches. Each of these settings are set by
flipping
only one switch. Does anyone know if more settings are possible using a
combination of switches? How can I monitor Vcore without frying CPU?
Any help or insight would be appreciated.

I have reverse engineered the Vcore supply for a PCChips M571
mainboard. If you feel up to doing the same for your m/b, then have a
look at these M571 pages:

I suspect that in your case you may have to play with resistor values,
probably by soldering extra resistors in parallel with existing ones.
You may be able to monitor the Vcore voltage by using a dummy load
resistor (eg 1 ohm 20W or 2.2 ohm 10W). Connect this resistor between
ground and a Vcore reference point. For the M571, I located an
appropriate Vcore pin in the single/dual rail header which was
labelled as P54C/P55C.

Thank you for the feedback.
Hopefully I can adapt your info to my board.
