Hi Vogons,

As many are aware, in some circumstances, misconfiguration mostly, PII and PIII class CPUs will boot on a 2x multiplier. Now I've done this accidentally or incidentally a few times on different boards, but other settings on those boards may result in no-post, which is of course, not useful

I am therefore wondering if there's some rhyme or reason to when it will go to a 2x multiplier, like maybe if set 1x higher than CPU locked multi or something.

The reason I ask is because I've gotta dismantle a laptop https://eurocom.com/ec/specs%283%29 to get it working, bad power socket, and while I'm in there, I wanted to rig a switch to make it go to 2x, but I don't know what BF pins/pattern to use for best chance of success. So not being a desktop board that's easy to run out of case to play with, and because with laptops you run risks of damaging them every time you take them apart (fragile clips stripping screws etc) I was hoping to zero in on something that's more of a sure thing, one and done.

Some threads around, but mostly talking about specific board/CPU combos, but I'm having a hard time aggregating a common principle out of the whole mess, so wondered if anyone knew.

thanks in advance for any clues....
