Vendor ID String
- When the parameter passed in EAX is 0 (zero), the register values returned upon
instruction execution are shown in the following table.
The values in EBX, EDX and ECX indicate an Intel processor. When taken in the proper order, they decode to
the string “
GenuineIntel
.”
Processor Identification
- When the parameter passed to EAX is 1 (one), the register values returned upon
instruction execution are:
31---------------------------14
4.6
Identification After Reset
