I guess, you are at the GRUB console here, just without display.

The only thing that is skipped is the display initialization. SeaBIOS does a legacy boot and detects the installed GRUB, runs it etc...

Interesting. A few days ago, I tried running Coreboot on the X201 with a SeaBIOS payload and no SSD installed. IIRC, SeaBIOS did provide a display at that point. But maybe I am misremembering, and the SeaBIOS display was actually something I only saw in QEMU.
That aside (which on reflection probably *was* in QEMU), your explanation makes perfect sense :) I hadn't realised that Coreboot's default would be *not* to initialise a display.
The GRUB payload, by default, doesn't have any configuration file and will wait at the prompt (no matter if the disk is encrypted or not).
Good to have this confirmed. From a GRUB prompt, I hope I will be able to find and boot the Debian installation.
In any case, how would more experienced Corebooters suggest I proceed?
Easiest option seems to be to select CONFIG_MAINBOARD_DO_NATIVE_VGA_INIT
Hope that helps,
Very much so; will try it ASAP. Thank you!
