Section B — Technical concepts 7. Stored in nonvolatile firmware storage (CMOS + NVRAM variables, sometimes within EC/ME/TPM or separate EEPROM). Firmware compares entered password by computing hash and comparing to stored hash; salts and hardware-bound secrets may be used on newer systems. 8. Historically vendors used challenge-response where a visible challenge (hex) plus vendor secret produces master password; tools reverse this mapping. Sharing or using such tools can enable unauthorized access and may violate terms of service or laws. 9. CMOS battery removal/RTC jumper: safe, low-tech, may clear user-set settings but often ineffective for modern models that store passwords in protected NVRAM/EC; risks low. EEPROM/BIOS chip reprogramming: invasive, can brick device, may violate warranty and legal restrictions, requires specialized equipment and consent. 10. DCU/Client Command Suite and iDRAC allow remote configuration, setting/resetting BIOS settings centrally; enterprise MDM can enforce/rotate credentials. These tools provide auditable, authorized ways to manage passwords without bypassing firmware protections. [ Your Locked Device ] ---> Displays Service Tag + Suffix (e
