PCI cards – notches, voltage and madness, oh my!

Ok, what a frustrating day. Tried to get a bloody PCI card working and learned the harder way about voltages and whether PCI 5v, 3.3v, PCI Express. Needless to say, I’ve been much happier being a network guy than keeping up with PC hardware changes over the last decade and PCI alone is a moving target it seems.

Anyways… wonder what all the different notches mean? Check out page 7 in this PDF – very good stuff:
