Don't get hit with the BIOS update hammer for COD MW4 like my colleagues - here's how to ensure you can play multiplayer and DMZ

If you're itching to get your pupils up against Call of Duty: Modern Warfare 4 on PC at launch on Friday, you should probably double-check your system is up to date. We've already had a couple of colleagues here flung against the wall of requirements with the new COD, requiring a BIOS update to play online.

That's because Activision explains that both TPM 2.0 and Secure Boot are required to play any online game mode (multiplayer or DMZ). More specifically, though, you must have a new enough version of PTT (Platform Trust Technology) for Intel systems, and fTPM (Firmware Trusted Platform Module) for AMD ones.

Secure Boot and TPM requirements themselves are part of the toolkit that many modern online games use to keep cheaters out. We've seen requirements for both, for instance, to play Battlefield 6. Secure Boot is what gives your firmware and kernel themselves signatures to ensure they are legit, and the TPM helps verify that everything boots up in order with no extra, malicious software or firmware thrust into the boot process. Intel PTT and AMD fTPM are implementations of TPM.

The key confusion with COD MW4 is that just having Secure Boot and TPM 2.0 doesn't seem to be enough on its own—old versions of PTT or fTPM won't work.

Activision says that, for Intel systems, if your TPM version is some form of 302.1.2.X or 303.1.2.X (where X can be anything), your motherboard may require a firmware update.
