Field upgrade is the TCG term for updating the TPM firmware. The update can be between TPM 1.2 and TPM 2.0, or between firmware versions. Some vendors limit the number of transitions between 1.2 and 2.0, and some restrict rollback to previous versions. [citation needed] Platform OEMs such as HP [85] supply an upgrade tool.
Prior to AMT version 11, CSME was called Intel Management Engine BIOS Extension (Intel MEBx). [1] Management Engine (ME) – mainstream chipsets [21] Server Platform Services (SPS) – server chipsets and SoCs [22] [21] [23] Trusted Execution Engine (TXE) – tablet/embedded/low power [24] [25] It was also found that the ME firmware version 11 ...
Software versioning is the process of assigning either unique version names or unique version numbers to unique states of computer software. Within a given version number category (e.g., major or minor), these numbers are generally assigned in increasing order and correspond to new developments in the software.
Firmware hacks usually take advantage of the firmware update facility on many devices to install or run themselves. Some, however, must resort to exploits to run, because the manufacturer has attempted to lock the hardware to stop it from running unlicensed code. Most firmware hacks are free software.
Tivoli Provisioning Manager (TPM) is a product in IBM´s Tivoli Software brand. Its purpose is to automate the provisioning of virtual servers and software. TPM is a "manager of managers", in that it does not manage any hardware itself, but issues commands to the hypervisors that do actually manage the hardware.
Furthermore, the TPM has the capability to digitally sign the PCR values (i.e., a PCR Quote) so that any entity can verify that the measurements come from, and are protected by, a TPM, thus enabling Remote Attestation to detect tampering, corruption, and malicious software.
A "personal computer" version of Windows is considered to be a version that end-users or OEMs can install on personal computers, including desktop computers, laptops, and workstations. The first five versions of Windows– Windows 1.0 , Windows 2.0 , Windows 2.1 , Windows 3.0 , and Windows 3.1 –were all based on MS-DOS, and were aimed at both ...
This is achieved by only transferring the differences between the old firmware and the new firmware, rather than transmitting the entire firmware. A delta of the old and new firmware is produced through a process called diffing; then, the delta file is distributed to the end-device, which uses the delta file to update itself. [8]
