Everything is described in a great detail here: complete list of tools and where you could buy them (need to spend from $0 to $30, depends on what tools you already have), how to connect these tools properly, a lot of helpful photos - for example, photo of G505S motherboard, so you could easily see where is that BIOS chip with 8 legs is located, dont need to spend time reading the motherboard chip labels. While this instruction mentions Bus Pirate USB flasher, the instructions for CH341A USB flasher are exactly the same - only a flashrom command is different (could see this command at the end of page) My current coreboot build is from December 2016 - it is not the latest, but still pretty recent, so I am not going to rebuild it from scratch yet. Still, there is one component inside BIOS image that could be easily updated: KolibriOS, tiny wonderful open source operating system that fits on a floppy. It could be launched from SeaBIOS Boot Menu, and works as a RamDisk (no changes to your computer saved). After you tell that you are prepared for hardware BIOS flashing, I will take KolibriOS latest daily build, add it to ROM and send a complete coreboot BIOS ROM to you Please reply if you have any questions Best regards, qmastery ----------------------------------------------- Is it possible to also reflash the USB firmware at the same time in case it has been tampered by Bad USB ? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
