Identification Information
The Intel Xeon processor MP can be identified by the following values:
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. Please refer to the Intel
Processor Identification and the CPUID Instruction Application Note (AP-485) for further
information on the CPUID instruction.
Family
1
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.
Model
2
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.
Brand ID
3
3. The Brand ID corresponds to bits [7:0] of the EBX register after the CPUID instruction is executed with a 1 in the EAX register.
