Identification Information

Component Identification via Programming Interface

The Intel® Celeron® processor 500 series can be identified by the following register

contents:

Family

Model

Model for A-1 step

0110 1111 10000

NOTES:

1. The family 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 registers accessible through boundary scan.

2. The model 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 registers accessible through boundary scan.

The stepping of the Intel Celeron processor 500 series can be identified by software

with its CPU signature:

Stepping CPU Signature

A-1 10661h

E-1 06FAh
