Any way to set the jumpers on the Lucky star LS-486 motherboard to ( 40mhz x 4 )
I see there is a 40mhz setting but I dont see a setting for multiplier in manual.

I have done this twice with LS-486 motherboard and it works.

Basically you use multimeter to check which cpu type setting jumper pin is connected to that R17 hole in socket and find a jumper pin next to it that is connected to ground and setting a jumper between those pins changes the cpu multiplier.

The settings for a 5x86 are on the bottom half of page 6.

I can't see how to set 3.45V for the core.
