Hello, I am looking to configure a CORE boot BIOS for my system, to replace the UEFI. I am uploading the YML and cpiogz file.

Hi @Zaro
Helping with coreboot is a little out of scope of Qubes community. That being said, I dont see your specific mainboard listed in the coreboot supported boards docs page or repo https://github.com/coreboot/coreboot/tree/master/src/mainboard/hp
@Plexus Hi, I understand that it is not currently supported for my specific board. That is the reason why I’d need help with it.
Could you please suggest resources where I can seek help to get coreboot for my system working?
Sure the best place to start is over at the coreboot.org community.
Theres also some old docs such as the https://www.coreboot.org/Developer_Manual
the modern docs are here
Porting a board can be quite a challenge 
Hi, i don’t want to discourage you, but you should look up the bios shure start protection. HP uses 2 Bios chips in which the signed HP Bios image is placed and if one of the chipses bios is replaced, it will be recovered. If you delete both of them or rewrite with another image, the laptop will be bricked. The main signed key from HP sits in EC firmware and if the EC gets two wrong signatures. The Laptop will refuse to boot. I tried to clean the me region on my Elitebook and ZBook no success.
Next thing, if intel boot guard is enabled you’re pretty much out of luck.
I would recommend to sell the laptop and buy a coreboot Laptop. Maybe a Thinkpad or a “System76” aka Clevo laptop.
But otherwise good luck and let me know if you have success
