What jumper settings?
If you're referring to the ROM_RECOVERY connector, that connector is used by a technician to connect an SPI EEPROM Programmer to reflash the BIOS in cases where the a user has attempted to flash the BIOS and it has failed.
If you don't own an SPI EEPROM programmer then you will need to take it to someone that has one and can reflash the BIOS SPI EEPROM with a working BIOS version.
