Okay, nice! I just looked it up and AMD calls their version fTPM (Firmware Trusted Platform Module). That's probably what you enabled and is now ready. But that wasn't a bad price you paid, and maybe a dedicated chip is faster? I have noticed that my boot time has increased 1-2 seconds after enabling the PTT and changing Secure Boot from Custom to Standard. So one or both of those things increased the boot time slightly. Maybe a dedicated chip is the way to go if you care about 1-2 seconds.
Yes, thanks. Your informative and very welcome post made me look into my AMD CPU and you are right, its fTPM 2.0 that is embedded in there, and so that is the reason why the Windows 11 checker gave my PC a "pass". I have looked into the difference between the fTPM firmware situation and having the physical chip, and much of the info is highly technical, but it seems that the chip is faster than fTPM and in some way that I don't (yet) understand, is more secure, though whether the difference in security for a home environment is significant remains to be seen.
My TPM chip is on order from SCAN for £14 (I live quite near their shop), and when they notify me, I'll go and collect it (I always like looking round their shop).
Your comment about boot-up time is interesting...I do want faster booting, but I think that I have reached the speed limits of what my BIOS can do in that respect. I've also used the Autoruns64 app from SysInternals to stop all sorts of stuff once past the Bios. I noticed that in their publicity, Microsoft claim that Win11 gives faster bootup, but given the checks that TPM performs, your comments about increased boot times are what I expected. How that fits in with Microsoft's claims about faster booting????
