processor
Extreme Edition 955, 965 and can be identified by the following values:
Family
1
Model
2
1111b 0110b
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.
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).
