Intel Xeon Processor LV and ULV Specification Update

Identification Information
16 Specification Update
Identification Information
Component Identification via Programming Interface
The processor stepping can be identified by the following register contents:
Family
1
Model
2
0110
1110
NOTES:
1. The family corresponds to bit [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 family corresponds to bit [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 generation field of the Device ID register accessible through Boundary Scan.
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. Refer to
the Intel Processor Identification and the CPUID Instruction Application Note (AP-485)
for further information on the CPUID instruction.
