Identification Information
The Pentium 4 processor on 90 nm process can be identified by the following values:
Family
1
Model
2
1111b 0011b
1111b 0100b
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
register 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
register accessible through Boundary Scan.
