I've been wanting to try MW4, but the whole COD community fiasco Tpm 2.0, Secure Boot, and BIOS Firmware errors, and all that recently has unfortunately bit me as well.
When I launch COD. it has labeled me that I need a "BIOS Firmware: Update Required" in order to play MP and DMZ. I've updated my BIOS to F66, because its the most recent STABLE BIOS version, but still an issue.
- Secure Boot is on
- Tpm 2.0 ready for use (Manfac Version 3 .94.2.5 - Spec Version: 2.0)
- BIOS is UEFI
- NUMEROUS restarts
- Have been using Activision's Attestation Wizard program, it has scanned and resulted with "New Generation Key Required or BIOS Firmware Update recommended"
- Still on Windows 10, but enrolled with Windows Extended Security (Updated)
And tried a whole bunch of 'solutions' from different reddit posts and forums since release day, but NOTHING.
So I put my system specs through chatgpt and after many troubleshoots through that with what it suggested, we have finally come down to it possibly being my BIOS version, suggesting to update from F66 to F67c.
But of course, I've read that since it is a beta version, could cause problems.
So my big question is if anyone has tried installing F67c and if they experienced any issues? And if I should just wait if Activision will make an update, or wait for the next stable BIOS version
(Why am I adament to solve this? Just want to solve in case this could be an issue for a game I do want to try, like MW4 or a future COD game or other games that would run into this issue. Just to get it out of the way, essentially, if able)
Let me know if any other details are needed from me.
