In one aspect, a system includes a service processor (SP), having a processor, a non-volatile memory and a communication interface. The SP receives a component information of components of a host computer from a basic input/output system (BIOS) being executed at a central processing unit (CPU) of the host computer through the communication interface, and stores the received component information in the non-volatile memory. When the SP receives a managing instruction from a remote management computer to change the component information of at least one designated component of the components of the host computer, the SP updates the corresponding component information stored in the non-volatile memory based on the managing instruction. Once the component information is updated, the SP may, in response to receiving the component information from the BIOS, send the updated component information back to the host computer through the communication interface.
