Abstract
A method includes storing configuration data for a Trusted Platform Module (TPM) in a pre-boot environment such as Unified Extensible Firmware Interface (UEFI), reading the configuration data, and automatically configuring the TPM based upon the configuration data. The configuring includes storing values of TPM parameters in non-volatile memory of the TPM. A method includes UEFI firmware of a circuit board on an assembly line configuring a TPM. An information handling system includes UEFI firmware and a TPM. The UEFI firmware configures the TPM from a configuration file stored in memory of the UEFI firmware.
Claims20
An information handling system comprising Unified Extensible Firmware Interface (UEFI) firmware to:
- store configuration data for a Trusted Platform Module (TPM) in firmware memory, wherein the source of the configuration data is not the TPM;
- read the configuration data;
- and
- communicate with the TPM, thereby automatically configuring the TPM based upon the configuration data, the configuring including storing values of TPM parameters in non-volatile memory of the TPM.
A method comprising:
- storing configuration data for a Trusted Platform Module (TPM) of an information handling system in memory of Unified Extensible Firmware Interface (UEFI) firmware of the information handling system, wherein a source of the configuration data is not the TPM;
- reading, by the UEFI firmware, the configuration data;
- and
- configuring the TPM based upon the configuration data, the configuring comprising the UEFI firmware storing values of TPM parameters in non-volatile memory of the TPM.
A method comprising:
- storing configuration data for a Trusted Platform Module (TPM) of an information handling system in memory of Unified Extensible Firmware Interface (UEFI) firmware of a circuit board on an assembly line of an original equipment manufacturer (OEM) for the manufacture of the information handling system;
- attaching the TPM to the circuit board;
- reading, by the UEFI firmware, the configuration data;
- configuring the TPM based upon the configuration data, the configuring including setting values of TPM parameters, the values stored in non-volatile memory of the TPM;
- and
- shipping the information handling system to a customer.
