Look at our FSB_Sense circuit diagrams someone posted above. Then note that if you connect Vcore directly to the socket pin (SP) on the "LO" circuit, you short circuit the 10K pullup resistor and change the LO to a HI. This can be done with a fine wire u-loop/jumper between sockets AH30 and nearby Vcc = Vcore socket AK30...verify in socket/pins diagram in datasheet 25175.pdf.

Link to Circuits article to understand how reducing the pullup resistance from 10K ohms to 0 ohms (with the fine wire jumper) changes the "resistance ratio" of the signal circuit's "Voltage Divider" and so changes the signal circuit's voltage level.
And it's safe because the 1K ohm pulldown resistor "limits the current from Vcore to ground". Just be sure that the top of the fine wire jumper does not contact the circular bases of any other pins...maybe just cut a small groove between the 2 sockets to lower the wire jumper a bit just to be sure.
