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 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 !
