[coreboot] Back to original BIOS

[enrico pallazzo]

Hi Michael,

If t400 stock bios structure is similar, you might try restoring it 
using this procedure:

It worked for me to revert to stock bios from coreboot on a t420.
As you write only bios region, you don' t need the old backup of your 
chip. In fact, I flashed a version of the stock bios that was different 
from the one I had before coreboot.

Regards,
Florian
