Your Alienware Aurora R10 is being blocked from Warzone because the game’s anti‑cheat (Ricochet) requires a newer BIOS/fTPM version. On Ryzen‑based Aurora R10 systems this is the known “TPM Attestation Failure” issue, and Dell provides a special “I‑rev” BIOS to fix it.
What you need to do Check your current BIOS and fTPM version Press Win + R, type msinfo32, press Enter. Note BIOS Version/Date. Press Win + R, type tpm.msc, press Enter. Note Manufacturer Version (e.g., 3.92.x.x). If your BIOS is older than the latest public release, or your fTPM is on an older 3.x version, you likely need the I‑rev update.
Enable required security features in BIOS Reboot and press F2 to enter BIOS. Go to Security and ensure: TPM 2.0 / Platform Trust Technology (PTT) is Enabled Secure Boot is Enabled. Save and exit.
Request the I‑rev BIOS from Dell The I‑rev BIOS is not always listed on the public download page; you must request it through Dell support. Go to Dell Support: https://www.dell.com/support Enter your Service Tag (or select Alienware Aurora R10 manually). Click Contact Support or Get Help Now. Choose Chat or Phone.
Dell’s policy for this issue is to provide the I‑rev BIOS even for out‑of‑warranty systems.
Install the BIOS update Once Dell provides the I‑rev BIOS file or remote update: Run the BIOS update executable in Windows, or Follow the agent’s instructions for a BIOS flash via USB. Do not interrupt power during the update. After the update, reboot and verify the new BIOS version in msinfo32.
Verify Warzone compatibility Launch Warzone. If it still fails, re‑check: Secure Boot is enabled. TPM 2.0 is enabled and recognized in tpm.msc. Windows is fully updated.
