I've attached a photo of my MB with PLCC socket soldered in place. The 
red wire, when shorted to ground, activates the original BIOS chip. The 
red wire is the one closest to the 10k resistor.
Also, I've powered on my PC several times with an empty PLCC socket 
without any damage, just to confirm your findings.
