Abstract
This application discloses a method and an enable apparatus for starting a physical device, where the physical device includes N central processing units (CPUs) and at least one platform controller hub (PCH), N is greater than one. Each of the N CPUs is electrically coupled to a PCH in the at least one PCH. The method includes determining a second CPU in the N CPUs as the primary CPU when a fault occurs in a first CPU, where the first CPU is the primary CPU configured to start the physical device before the fault occurs in the first CPU, and triggering the second CPU as the primary CPU and in cooperation with a first PCH to start the physical device, where the first PCH is one PCH in the at least one PCH.

A method for starting a physical device, comprising:
- determining a second central processing unit (CPU) in N CPUs as a primary CPU when a fault occurs in a first CPU in the N CPUs, the physical device comprising the N CPUs and at least one platform controller hub (PCH), the N being a positive integer greater than or equal to two, each of the N CPUs being electrically coupled to the at least one PCH, and the first CPU being the primary CPU configured to start the physical device before the fault occurs in the first CPU;
- and
- triggering the second CPU as the primary CPU and in cooperation with a first PCH to start the physical device, the first PCH being electrically coupled to the second CPU, and the first PCH being one of the at least one PCH.
An enable apparatus for starting a physical device, comprising:
- a memory comprising instructions;
- and
- a processor coupled the memory, the instructions causing the processor to be configured to:
- determine a second central processing unit (CPU) in N CPUs as a primary CPU when a fault occurs in a first CPU in the N CPUs, the physical device comprising the N CPUs and at least one platform controller hub (PCH), the N being a positive integer greater than or equal to two, each of the N CPUs being electrically coupled to the at least one PCH, the enable apparatus being coupled to the N CPUs and the at least one PCH, and the first CPU being the primary CPU configured to start the physical device before the fault occurs in the first CPU;
- and
- trigger the second CPU as the primary CPU and in cooperation with a first PCH to start the physical device, the first PCH being electrically coupled to the second CPU, and the first PCH being one of the at least one PCH.
