This guide walks you through flashing a modified BIOS so your spoofed serials are written directly into the motherboard firmware. They survive Windows reinstalls, cloud resets, and restore points.

Stage 01
Motherboard Requirements
Compatibility check
Not every board supports this method. Check the requirements below before you start.
✓
Unlocked AMI BIOS — Most custom desktop motherboards (ASUS, MSI, Gigabyte, ASRock) use AMI and are unlockable.
✗
OEM / Laptops won't work — Pre-built desktops (Dell, HP, Acer) and laptops have locked firmware. Use the regular spoof guide instead.
ℹ
Open msinfo32 on Windows and check your BaseBoard Manufacturer to verify compatibility.

Stage 03
ARP Spoofing — optional
Network-level protection
If you've been banned multiple times, your ISP's gateway MAC can be flagged. An OpenWRT router between your PC and modem spoofs that layer too.
Recommended Router
Cheap, compact, and runs OpenWRT out of the box. Plug it between your modem and PC — no config needed beyond the Edgey guide.
