+ Use cbfstool from libreboot_util, or libreboot_src/coreboot/util/cbfstool/ if you want to build from source. +
+
+ ./cbfstool yourrom.rom remove background.png -n background.png
+ ./cbfstool yourrom.rom add -f background.png -n background.png -t raw
+
+ When you've done this, re-flash your ROM and you should have a new background at boot time. +
