Like almost everyone else on this board, I want to buy the creative sound blaster Audigy 2 ZS card for my laptop to hook up to the z5500. I just don't know if my compaq presario 2500 (model #2596US) has the required Typed II Card Bus Slot for it to fit. (PCMCIA) How do I tell? I checked my manuel but it only says that there is a card bus slot there. I don't know if it's the correct one or if I'll have to buy an expansion slot.... yeah any help is great
