Fixing 'Estado De Atestación Fallido' in Warzone: Visual Proof and Step-by-Step Bios Guide
By Alexander Ross
Flashing the BIOS resets many setup values back to stock defaults. To pass Ricochet's security attestation, you must align three critical BIOS parameters: boot mode, cryptographic module status, and certificate keys.
First, disable legacy compatibility. Locate the CSM (Compatibility Support Module) setting inside your BIOS Boot tab and set it to Disabled. Native UEFI mode must run exclusively. Operating under a Master Boot Record (MBR) partition will prevent Secure Boot from functioning; your Windows drive must use the GPT (GUID Partition Table) layout.
Second, activate platform trust. On AMD motherboards, navigate to the CPU configuration or Security section and enable AMD fTPM (Firmware TPM). On Intel motherboards, enable Intel PTT (Platform Trust Technology). Ensure the module state is set to Enabled and operational.
Third, resolve the Secure Boot state. Many users discover that Secure Boot shows as "Active" in the BIOS, yet Windows reports it as disabled. This indicates broken or uninitialized platform keys. Navigate to the Secure Boot sub-menu, set OS Type to Windows UEFI Mode, and locate the key management section. Select Restore Factory Keys or Enroll Default Keys. Save your changes and exit by pressing F10.
