Dear friends
I've followed the instructions to get +0.2V using this pen but still stuck to 540/890

I asked for a conductive ink pen but I tried with my multimeter and it seems not to be conductive....
could you tell me if this the case?

apart the possibly wrong pen, is it ok the work i've done?
It's not necessary to touch the BIOS, is it?
