Hello,
I got the following output via RS232 console: ------------------------------------------------------------------------------ coreboot-4.9-539-gde3ace0-dirty Mon Jan 28 13:44:10 UTC 2019 romstage starting (log level: 7)...

It seems payload is not running. Currently SeaBIOS is enabled.
My goal it to boot vanilla linux with grub (or grub2) via RS232 console only. With the original BIOS I got from vendor, I used knoppix to burn grub on the SATA disk. If coreboot is running grub, how should I burn grub ? Is it part of coreboot image ?
Thank you, Zvika
