PCI/mPCI/cardbus device

Hi pod,

I'm not sure whay you're asking here. But PCI, mini PCI, Cardbus are basically

all the same.

> How expensive is the licence if not in opensource ?

It can vary quite significantly. I've seen numbers anywhere from

3000 to 12,000 USD ... plus or minus royalties.

For standard 32-bit PCI:

------------------------------

32 - Address/Data

4 - Command/Byte Enable

13 - Control

1 - Clock

I don't know what signal addition/removal (if any) for CardBus or mini PCI.

Although, I've been told that mini PCI is identical to 32-bit PCI WRT the

functional signals.
