Hi Aaron, first thanks to take the time to answer :)

SeaBIOS was loading correctly until you changed the GBB flags, right? And CTRL+L is just not being detected any longer? Can you change the GBB flags back and determine if the legacy booting still works?
Yes, before doing mess with the gbb flags, the SeaBIOS was correctly working : I have once installed Fedora on my c720 Now CTRL+L is no longer detected (only a sound out the speakers)
Yes I can change the GBB flags, but which one do I have to set ?
I have read online it may be caused by the wipe of SeaBIOS part in the ROM.
It's possible. Since you are in dev mode, could you run the following? ' iotools mmio_dump 0xffc00000 0x200000 -b | hexdump -C' It will dump the contents of legacy portion of the flash. We'd know for certain if the area is wiped.
I have copy/paste your command, and here is what I obtain :
localhost / # iotools mmio_dump 0xffc00000 0x200000 -b | hexdump -C bash: iotools: command not found
(before doing that I have entered « shell » and « sudo bash »
Thanks !
