GRUB also ships with a module to print the CBMEM console with the
command `cbmemc` [1]. You’ll probably need to rebuild GRUB and put it
for example on a USB storage device and choose that from SeaBIOS’ boot
menu.

Unfortunately, I have no idea, how you can store that output without a
serial console. You could take pictures. Probably GRUB has some support
to write to a file, but I do not know how.


Thanks,

Paul
