I have an ASUS Vivobook V551LB-DB71T. It's a mouthful of a name, but it has decent performance. It doesn't have an expresscard or thunderbolt port, but I was looking at the PE4H series of pci adapters, and I saw that it has an 'mPCI' adapter for the cable. (The PE4H-PM3N-060B Package.) From what I've seen, it looks like the slot you put laptop wireless cards into, and this laptop just happens to have two of those inside it, one already taken by a wireless card.

So is that right? can I use the PCI adapter with the slot in my laptop? Or am I mistaken, and mPCI is different to what I think it is?
