IF your board supports 1.5V and IF that's what the CPU is modded to, rather than the over specific 1.45 or so that coppermine boards don't understand, then there's a chance you'll get as far as your BIOS complaining about an unrecognized CPU. (Some will go "meh, it looks PIII-ish, we'll assume it is and boot.", some will go "it does not match the model name strings in my whitelist so I will assume it's a terrorist plot to blow me up, hence I will freeze and do nothing."
