Features
7.1
Power-On Configuration Options
Several configuration options can be set by hardware. The Dual-Core Intel Xeon processor 7000 
series samples its hardware configuration at reset, on the active-to-inactive transition of RESET#. 
For specifications on these options, refer to 
The sampled information configures the processor for subsequent operation. These configuration 
options can only be changed by another reset. All resets configure the processor. For most reset 
purposes, the processor does not distinguish between a “warm” reset and a “power-on” reset.
7.2
Clock Control and Low Power States
The processor allows the use of HALT and Stop-Grant states to reduce power consumption by 
stopping the clock to internal sections of the processor, depending on each particular state. The 
Dual-Core Intel Xeon processor 7000 series also adds support for the Enhanced HALT state. For 
more configuration details also refer to the Prescott, Nocona and Potomac Processor BIOS 
Writer’s Guide
.See 
 for a visual representation of the processor low power states.
