NOTES

• The Extended Family, Bits [27:20] are used in conjunction with the Family Code,

specified in Bits[11:8], to indicate whether the processor belongs to Intel

Core

™

processor family.

• The Extended Model, Bits [19:16] in conjunction with the Model Number, specified

in Bits [7:4], are used to identify the model of the processor within the processor's

family.

• The Family Code corresponds to Bits [11:8] of the EDX register after RESET, Bits

[11:8] of the EAX register after the CPUID instruction is executed with a 1 in the

EAX register, and the generation field of the Device ID register accessible through

Boundary Scan.

• The Model Number corresponds to Bits [7:4] of the EDX register after RESET, Bits

[7:4] of the EAX register after the CPUID instruction is executed with a 1 in the

EAX register, and the model field of the Device ID register accessible through

Boundary Scan.

• The Stepping ID in Bits [3:0] indicates the revision number of that model.

• When EAX is initialized to a value of '1', the CPUID instruction returns the

Extended Family, Extended Model, Processor Type, Family Code, Model Number

and Stepping ID value in the EAX register. Note that the EDX processor signature

value after reset is equivalent to the processor signature output value in the EAX

Cache and TLB descriptor parameters are provided in the EAX, EBX, ECX and EDX

registers after the CPUID instruction is executed with a 2 in the EAX register.

PCI Configuration Header

Every PCI-compatible function has a standard PCI configuration header, as shown in

the table below. This includes mandatory registers (Bold) to determine which driver to

load for the device. Some of these registers define ID values for the PCI function,

which are described in this chapter.
