Preparing your computer for coreboot
In order to easier coreboot debugging(really usefull when something goes wrong) you should consider making your computer coreboot-ready before installing coreboot.
Output for production
If you have a serial port, you should consider Enabling the Serial Console in:
- The payload(if you use Seabios from coreboot's "make menuconfig" it's already done for you)
- The bootloader like grub
- The kernel(like the linux kernel)
- The init system(systemd, sysvinit etc...)
if you don't have a serial port you could enable the USB debug port in coreboot and grub. However in my GNU/Linux disribution(Parabola, based on arch) they didn't enable it for the linux(-libre) kernel.
