In certain aspects, a system for out-of-band configuring BIOS setting data (BIOSSD) includes a host computer and a service processor (SP). The SP stores a BIOSSD collection and a human interface data (HID) collection. The HID collection includes questions for data of the BIOSSD collection and corresponding options for each question. When a remote management computer sends to the SP an information request, the SP retrieves the HID collection and transmits the questions and the corresponding options to the remote management computer. In response to a command indicating a selected corresponding option, the SP changes corresponding data of the BIOSSD collection according to the command. When the BIOS executed at the host computer issues a BIOSSD update request to the SP, the SP transmits a copy of the BIOSSD collection to the BIOS chip of the host computer to replace the BIOSSD collection stored in the BIOS chip.
