Motherboard Serial

The motherboard serial number is one of the most commonly checked hardware identifiers by EAC, BattlEye, and Vanguard. Tensai's spoofer reads the current serial from SMBIOS table 2 (Baseboard Information), then overwrites it with a random value generated at each boot.

This is done entirely in firmware memory — no Windows API calls, no kernel drivers involved.

• Reads from SMBIOS table 2
• Randomized on each boot
• No detectable API calls

SMBIOS & DMI Tables

SMBIOS (System Management BIOS) tables contain identifying information about your system: manufacturer, product name, serial numbers, UUIDs, and more. Anti-cheats read these tables directly from memory to build a hardware fingerprint.

Tensai uses AMIDEEFI — a UEFI application that directly modifies these tables in firmware memory before Windows boots. Every identifying field is replaced with spoofed values.

• Covers SMBIOS tables 1, 2, 3 (System, Baseboard, Chassis)
• AMIDEEFI-based firmware modification
• All identifying fields spoofed

Disk Drive Identifiers

Storage device serial numbers (both HDD and SSD) are a persistent hardware identifier that anti-cheats commonly fingerprint. Tensai cleans:

• Disk drive serial numbers (IOCTL_STORAGE_QUERY_PROPERTY)
• Volume IDs and volume serial numbers
• Drive controller identifiers

Cleaning happens at the firmware level before the OS boots, so Windows and anti-cheats see the spoofed values as genuine.

MAC Address Spoofing

MAC addresses are used by anti-cheats as a secondary hardware identifier, especially when cross-referencing with other banned systems on the same network segment.

Tensai spoofs MAC addresses at the adapter level using randomized locally administered addresses that persist across reboots.

• Spoofs all active network adapters
• Randomized locally administered addresses
• Persists across reboots

Reboot Persistence

Because the spoofer modifies firmware tables as a UEFI boot entry, the spoofed values survive full power cycles — not just soft reboots. The system boots up already clean every time.

No need to re-run the spoofer after turning your PC off and on. It's a one-time setup.

• UEFI boot entry approach
• Survives cold reboots and power loss
• One-time setup, no re-running needed

✕

Undetected Method

Most HWID spoofers use kernel drivers (like RTCore64 or WinRing0) that are already blocklisted by anti-cheats. Tensai's spoofer avoids the kernel entirely by running as a UEFI boot application.

There is no driver to detect, no usermode process to scan, and no Windows API pattern to signature. The modifications happen in firmware memory before Windows even starts loading.

• No kernel driver required
• No usermode hooks or processes
• No detectable Windows API calls
