Abstract: The present disclosure discloses a power management method to improve a power-on effect of a multinode system. In the power management method provided in the present disclosure, after a power management module delivers a power-on instruction to each node in the multi-node system, a PCH of each node loads a BIOS from a local flash to perform a power-on process. Compared with the prior art in which a PCH of a master node is responsible for loading BIOSs of all nodes in a multi-node system, the method provided in the present disclosure can reduce burden on the PCH of the master node, and accelerate a power-on speed of the system, so that a better power-on effect is achieved. The present disclosure further provides a related multi-node system.
