JepZ on Jan 6, next [—]. Therefore, everybody on this planet has to run hardware with a lot by all odds of unpublished zero-day vulnerabilities. Scaevolus on Jan 5, prev next [—]. I think "remote" here means "host to TPM chip". Which is still bad, but not on the level of "install a rootkit on a powered-off machine" like some of the Intel ME exploits.

I reset the Bios to factory optimized settings which on my board enables CSM and fTpm trying to reinstall windows I would get the same error, I attempted to install UEFI windows with fTmp enabled but leaving secure boot disabled CSM enabled, which is my motherboard optimized default and I just get a light blue screen with No error, but it just sits there and does nothing, after a while the PC shuts down. I reached out to Gigabyte and of course they tell me it is not their issue that fTpm is part of the CPU. I have tried all the troubleshooting steps suggested to me and nothing seems to work, I can either install windows 10 with the CSM enabled and fTpm enabled in a "legacy" bios or I can keep fTpm disabled and install windows 10 in UEFI mode secure boot but not both and both is needed for Windows I am not a total novice when it comes to computer repair, but this issue has me stumped. Could it be that the CPU is malfunctioning? In the Bios when fTpm is enabled it does show manufacture info such as AMD and version number , however as mentioned this is not shown in windows, I try to run tpm. I even tried to install windows using default settings in bios, legacy mode which installs windows using MBR partition and not GPT and then using mbr2gpt convert the drive, the second I restarted the PC I received the "recovery error" mentioned above, and once fTpm was shut off, windows booted fine into UEFI mode GPT partition I am hoping someone can help with this issue, as luck has it, my CPU's warranty expired 2 days before all this happening, which makes me wonder, but that is for another time. Go to Solution. For any following this post I have resolved the Issue, turns out it was a bios issue, although reinstalling newest Bios did not resolve the issue, nor did rolling back bios to a few earlier versions, however after exhausting all troubleshooting I decided I had nothing to lose and downloaded all 17 bios updates for my board, and starting from first bios I installed them in order, and now everything is working as expected once again. I am not sure which bios update fixed the issue, I know it was not the last 3 though as I had installed and reinstalled those ones with no success, either way PC is now running windows 11 with fTmp and UEFI. View solution in original post. I am using the bios put out by Gigabyte to enable Ftmp I have also tried using the latest Bios available, same results. If i leave fTpm enabled with CSM enabled, secure boot disabled I can install windows however window will install in "legacy Bios" using MBR rather than the GPT that UEFI requires, If I disable fTpm and enable secure boot disable CSM then I can install windows in UEFI, I just can't seem to get both to work at once, As I mentioned In the Bios the fTmp does list manufacture and version number, however in Windows Device security it does not , troubleshooting mentions not being able to find the device info to contact manufacture, however I have found no way to contact AMD direct about this, and as mentioned my warranty expired about 2 days before this issue started, convenient I suppose. By the way I user whose AMD processor also expired about 2 or 3 days later found out he had a bad processor.

Not physical things, not energy, information.

Can't really verify that it's off, though. That's switch for TPM features only. You cannot disable PSP as it is responsible for x86 initialization. Sounds like a job for refactoring. Admittedly, I'm mystified what this "memory training" even is. Where's this memory training fit in? Modern high speed links are very finicky, to the extent that various parameters timing, etc.

As a quick reminder, the purpose of PSB is to provide a hardware root-of-trust that will verify the integrity of the initial UEFI firmware phases, thereby preventing persistent firmware implants. In this part of the blog series, we will dig deeper into the nitty gritty details of PSB, including a first glimpse of how it works under the hood, how it should be configured and, naturally, how various major vendors fail to do so. For the sake of brevity, we won't go into detail on the purpose of each phase as it has already been widely covered already e. In order to understand the trust hierarchy in more depth, we will first take a look at how the UEFI firmware, stored in the SPI flash, is structured. Once again, for the sake of brevity, as the structure is relatively complex, we will only focus on portions relevant to the chain-of-trust.

The PSP has a 4. The PSP Key is also used to authenticate the processor to the operating system and other system components. The PSP Key is used to generate a unique digital signature that is used to authenticate the processor. It helps to ensure that only authorized processors are able to boot and operate on a system, and that sensitive data and operations are protected from unauthorized access.

Disadvantages of plyometric training

Hope this helps someone out there who's facing similar issues. Good luck! Too easy to break system with one wrong step. For example, if there's an option to enable both the fTPM and the hardware TPM, try disabling one of them to see if it makes a difference.

Again, there is nothing you can do is wasm that you can't already do it javascript. Seriously doubt it. It's blob which is loaded into DDR controller, and for some reason FSF thinks it is wrong to memcpy that blob using main cpu, but it is fine if you memcpy it using secondary core. Since, wasm makes that easier and more efficient, I'm opposed to it. AI-generated content is not permitted on Ask Ubuntu.

It is clear that we do not, so certification of hardware is most likely to just ensure every chip has the same exact problems. Exploring what inspired folks to start coding. I now have all the correct setting that Windows 11 wants running, after many days and many reinstall attempts plus a clone disk.
