PCI slots and wireless adapter

Last response: in Motherboards

All the open PCI slots in my Dell XPS 630 are 2 black colored slots with one notch each, but all the wireless adapters that I found have 2 notches.
Are there any wireless adapters that can fit into my one notch black slots? :bounce:

The two notches are 'universal' fit. Previously, there were voltage differences in the different PCI slots that made interchanging components very risky so the slots were keyed, 3v if one way, 5v if the other. 'Universal' cards have overcome that limitation and have two key slots to fit either design.
Hope it helps

Dear C12Friedman:

Do you mean that I can get those wireless adapters with 2 notches to fit into my open black color PCI slots which has 2 notches? One of the black PCI is 1/2 length of the other black PCI slot. Do you have an e-mail so that I can send you the image of the open PCI slots in my motherboard? you can e-mail me at

Thanks a lot
