I'm following your project, although at one time I chose dell m4800 and old alienware as platforms for experimentation). Could you please provide a link regarding possible support for 4G Decoding and ReBar in Coreboot? Because it is a prerequisite to upgrade mxm gpu to Ampere generation. Here you go: https://www.phoronix.com/news/Coreboot-Resizable-BAR EDIT: Haswell may have problem with Coreboot because thanks to Intel (TM) Boot Guard. Your mileage may vary. I had already tested this alternative BIOS simplifed version, and it works! Now I need to compile updated version with corrected bugs and graphical interface. Never though I would be making my own bios hahaha! Link to comment Share on other sites More sharing options...

GuitarG Posted November 17 Author Share Posted November 17 Adapter for faster debuging on spare 8570w, I will make same later for main one. I plan to make mini board with dual bios, one coreboot and second will be original hp one. I can test much faster now. Right now I can boot linux, but I have no visible BIOS and fans don't work on my compiled coreboot. BTW, did you know different flash IC's loads time is varies? You can tell by how long it takes from power button to visible BIOS logo. Macronix is x2 faster than original winbond on my main notebook 🙂 On left main one vs test on right. Both with latest updated firmware. Coreboot is even faster (but I don't have video for now) D2P0Obbj.mp4 Link to comment Share on other sites More sharing options...
