Ad. 1. Currently we have all Alder Lake processors / SoCs well supported in coreboot. One can build a working images with legacy BIOS boot support using SeaBIOS payload or UEFI compliant boot support using TianoCore EDK2 UEFI Payload. Having a Linux payload/LinuxBoot is also possible. What may be a significant difference between the BIOS from AMI and coreboot solutions is the setup options. coreboot by itself does not provide any runtime configuration options, this task is shifted to the payload. Currently the most feature rich is UEFI Payload which offers some basic setup menu for UEFI Secure Boot, TPM configuration and boot order. Ad.2. That solely depends on the company who will do the work (and their current workload). I advise to contact a coreboot consultants, e.g. from this site: https://www.coreboot.org/consulting.html This page: https://doc.coreboot.org/distributions.html should also give you an overview who is doing coreboot work and ships coreboot on their devices. Ad.3. Besides the board specifications (what components are used, etc.), having a board schematics is a huge help for coreboot developers and most consultants will ask for it. It is possible to develop coreboot without schematics, but it will take much more time and resources to make everything working as expected. Optionally a board PCB view may also be helpful. > > at this moment we use BIOS from AMI: > Vendor: Amerian Megatrends > Core Verion: 5.27 > Compiancy: UEFI 2.8; PI 1.7 > etc... > > About us > We are Shenzhen Wesion Technology Co., Ltd is the company that owns the brand > "Khadas", our company was founded on 5 November 2014.
