[RESPONDED] Coreboot on the Framework Laptop

I think for the end user thats only helpful when they have an eeprom programmer to put the bios image on the new chip unless framworks starts to sell pre-programmed chips. There is also the danger that a DAU would remove the chip for an extended period of time which would reset the enitre bios and system clock. If the boot order gets messed up because of the reset then you might look at a laptop that refuses to boot .

Not exactly, if SPI controller is supported by flashing tool e.g. flashrom one can hot swap chips. It would work as follows:

• boot your platform to OS with functional BIOS storage
• while system booted remove BIOS storage
• place second chip (spare one) in socket
• flash development/debug version of coreboot/BIOS/UEFI
• reboot the platform and gather logs
• modify you coreboot/BIOS/UEFI code and repeat until you get working firmware

I will teach that technique in free OST2 training called Architecture 4032: coreboot Hands-On
