Hello Rene(?), Thanks for reaching out and appreciate your offer to help test. I'll prioritize porting Sabertooth Z77.
coreboot has an issue tracker at https://ticket.coreboot.org/projects/coreboot. However since this is a "new" board not previously in tree (but with support for he individual components), I'm not sure under what category issues with this new port should be reported. However, issues reported there are sent to the mailing list as well, so I should see them. Having said that, email and the list is the best way to reach me. Also because this is a new board to coreboot, it will first appear as a change on gerrit (https://review.coreboot.org). Usually you would have to get the source, apply the patch, and compile. I can precompile a binary and get it to you somehow to test, probably with a Google Drive or OneDrive link. That can be worked out later. Usually, I have to get a dump of the flash chip with vendor firmware to get the SPI descriptor. A full dump is also a great backup in case the port doesn't boot. For that you probably want one of those little CH341 SPI programmers. You'll pop the chip out while your board is running, dump it and put it back. Then get that dump file to me. This dump file will also allow me to integrate the SPI descriptor and ME firmware so you can flash my precompiled binary whole. I'll also need to run autoport on your stock board for things that I can't get otherwise like HDA and super IO config. It's a porting tool that's part of coreboot sources that automates much of the necessary data dumping. It needs Linux and Go though. The wall of text above re chip dumps to say I haven't looked deep enough about BIOS flashback on Asus boards. They do it with a very proprietary, separate microcontroller that can control the SPI flash chip, and they take the .CAP vendor firmware update file stored on a USB drive plugged into a specific USB port, which is NOT a straight dump of the BIOS area of the SPI chip. Any questions feel free to ask. Again thank you for your help in testing. Regards Keith On Mon, Dec 23, 2024, 17:44 R S <rene.shus...@bcsemail.org> wrote: > Hi Keith, > Appreciate the undertaking.
