@junaruga the current UEFI BIOS is a proprietary product made by [Insyde Software](https://www.insyde.com/products). The embedded controller firmware (controls stuff like battery management, power button behavior, etc) is based on [Chromium OS EC](https://chromium.googlesource.com/chromiumos/platform/ec/+/HEAD/README.md). > [@\[RESPONDED\] Coreboot on the Framework Laptop](http://community.frame.work/t/free-the-ec-and-coreboot-only/791/5): > > Yep, open source firmware is well aligned to our mission of building products that are better for people and the planet. Our EC firmware is based on chromium-ec, and we will be releasing source. As @Kieran_Levin noted, we’re also exploring coreboot. We’re currently focused on getting the Framework Laptop out into the world in a lower-risk path that uses an off the shelf proprietary BIOS, but we’re looking forward to replacing that with an open alternative in the future. Removing the G-Sensor option in the BIOS would have been at the direction of Framework, presumably to maintain consistency between different production batches since they’re [removing the accelerometer from the motherboard due to supply issues](http://community.frame.work/t/why-is-there-an-accelerometer/3685/14). --- _[View the full topic](https://community.frame.work/t/bios-guide/4178)._
