The change-log specifically mentions changes to the update procedures for ME / TXT updating, I’m wondering if this BIOS is just bad or the TXE unit dying on its own is a thing (would be quite the coincidence). I already tried re-flashing the BIOS again, it shows no errors but doesn’t help. (Intel(R) Trusted Execution Engine Interface driver has failed to perform handshake with the Firmware (FWSTS0: 0x01040190, FWSTS1: 0x100A0000).)Īlso the TXE Information section inside the BIOS settings shows “ N/A” for both Sec RC Version and TXE FW Version, this was definitely not the case right after updating the BIOS.
Intel TXT uses a Trusted Platform Module (TPM). Looking for errors I noticed in device manager the Intel Trusted Execution Engine has a yellow exclamation markĪnd in event log there is an error for TXEI圆4 Providing of a trusted operating system with additional security capabilities not available to an unproven one. Hi, I updated my ZBOX CI323 nano (Intel Celeron N3150) BIOS to the latest version 2K160913 and it went fine, but a day or so later I noticed the CPU is slower than usual.
