# Someone built a BIOS for the ESP32-C6, bringing a PC-like architecture to the $2 chip

**[XDA Developers](https://daily.dev/sources/xda-developers)** · 2 min read · 0 upvotes · 0 comments

## Summary

OpenC6 is an open-source BIOS-like firmware for the ESP32-C6 microcontroller that reimagines the $2 chip with a PC-style architecture. Rather than monolithic firmware, it acts as a host platform that initializes hardware, provides out-of-band management via an LP-Core coprocessor, and exposes a standardized System Call Interface (ABI). This lets developers hot-swap, download, and execute tiny bare-metal payloads directly into RAM or Execute-In-Place (XIP) Flash. The project is still in progress, with open bounties for features like a fully open-source file system and execution security measures.
