Mini-PCI Bus 100-Pin Pinout

The MinPCI bus is used in Laptop and NoteBook computers.
Mini-PCI uses a reduced pinout than the normal PCI bus used in Desktop 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.

The Peripheral Component Interface 'PCI' Bus was originally developed as a local bus expansion for the PC (ISA) bus. The PCI spec defines the Electrical requirements for the interface. No bus terminations are specified, the bus relies on signal reflection to achieve level threshold. The first version of the PCI bus ran at 33MHz with a 32 bit bus (133MBps), the current version runs at 66MHz with a 64 bit bus. The PCI bus operates either synchronously or asynchronously with the mother board bus rate. While operating asynchronously the bus will operate at any frequency from 66MHz down to (and including) 0Hz. Flow control is added to allow the bus to operate with slower devices on the bus, allowing the bus to operate at their speed. PCI is an unterminated bus, the signal relay on signal reflections to attain there final value.
