4.6Register Map and Miscellaneous Functions

System Support

The RPM (speed) of all fans is the result of the temperature of the CPU as sensed by speed control circuitry. The fans are controlled to run at the slowest (quietest) speed that will maintain proper cooling.

✎Units using chassis and CPU fans must have both fans connected to their corresponding headers to ensure proper cooling of the system.

4.6Register Map and Miscellaneous Functions

This section contains the system I/O map and information on general-purpose functions of the ICH10 and I/O controller.

4.6.1 System I/O Map

Table 4-9 lists the fixed addresses of the input/output (I/O) ports.
