The MinPCI bus is used in Laptop and Note-Book computers.
Mini-PCI uses a reduced pinout than the normal PCI bus used in Desk-top computers.
There are 2 different connector pinouts defined in the Mini-PCI specification,
one for type I and type II, and another connector for type III.
The Mini-PCI standard is a Parallel bus standard based on the Parallel
PCI bus standard, which is different than the
ExpressPCI bus standard.
