FIELD: information technologies.
SUBSTANCE: data of serial interface for detection of dual-in-line memory module (DIMM) presence in electronically erasable programmable read-only memory (EEPROM) is encoded using closed key of motherboard with which this dual-in-line memory module (DIMM) is to be used, so that only basic input-output system (BIOS) of specified motherboard could decode presence detection serial (SPD) interface data to complete downloading.
EFFECT: improving protection of computer system integrity by blocking the use of memory modules retrieved from original motherboard in another motherboard.
