Hello Mike, Thank you for your response. I could run coreboot.rom on QEMU by the command you told me.

Thank you for your try. I also ran coreboot + SeaBIOS + HariboteOS on QEMU. It seemed to work well. This is my hobby project, so a lot of functions are limited. Currently, HariboteOS doesn't support enlarging a console window. Thank you, Asami Doi 2019年3月24日(日) 16:35 Mike Banon <[email protected]>: > Good day, Asami!
