Chapter 1. Introduction
This chapter introduces Intel NM10 Express Chipset and provides information on
manual organization and gives a general overview of chipset.
Chapter 2. Signal Description
This chapter provides a block diagram of Intel NM10 Express Chipset interface signals
and a detailed description of each signal. Signals are arranged according to interface
and details are provided as to the drive characteristics (Input/Output, Open Drain, etc.)
of all signals.
Chapter 3. Intel NM10 Express Chipset Pin States
This chapter provides a complete list of signals, their associated power well, their logic
level in each suspend state, and their logic level before and after reset.
Chapter 4. Intel NM10 Express Chipset and System Clock Domains
This chapter provides a list of each clock domain associated with Intel NM10 Express
chipset in a chipset-based system.
Chapter 5. Functional Description
This chapter provides a detailed description of the functions in the Intel NM10 Express
Chipset. All PCI buses, devices and functions in this manual are abbreviated using the
following nomenclature; Bus:Device:Function. This manual abbreviates buses as B0
and B1, devices as D8, D27, D28, D29, D30 and D31 and functions as F0, F1, F2, F3,
F4, F5, F6 and F7. For example Device 31 Function 0 is abbreviated as D31:F0, Bus 1
Device 8 Function 0 is abbreviated as B1:D8:F0. Generally, the bus number will not be
