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.
