OpenC6 BIOS project brings PC-like firmware to ESP32-C6 MCU with network boot and OTA update support

OpenC6 BIOS is an open-source project that brings PC BIOS-like architecture to the ESP32-C6 microcontroller. Instead of combining hardware setup and application code into a single firmware image, it separates the base system from application payloads (2–10 KB). Key features include dynamic CPU frequency scaling, a System Call Interface (ABI) for Wi-Fi/crypto/math access without full ESP-IDF, PXE-like network boot over Wi-Fi, A/B OTA updates with rollback, a web-based BIOS setup interface, LP-Core health monitoring using the ESP32-C6's low-power RISC-V core, and Aura Sync RGB support. The project targets ESP32-C6 boards with at least 8MB flash and is available on GitHub under the MIT license.
