That gives the same as `bs=1M count=8` it's just a weirder way to tell `dd`. > > # Split last 4MB of coreboot.rom (top-chip) > dd if=coreboot.rom of=x230-coreboot-4mb.rom bs=1024 count=$[1024*4] > skip=$[1024*8] > > at least this is what I did - while it was good enough that my X230 is > booting up I still can't boot the secondary payloads (I have choosen nvramcui > and coreinfo).

Don't think you missed anything and your ways to split the image seem fine. But you might do too much already. Especially flashing anything but the BIOS region when you want to track down coreboot issues makes things harder to reason about. --snip-- > 12) Configure Coreboot (make nconfig) > choose parameters/features and add the 4 binary blobs (step 8 and 11) Please attach your .config file. Nobody can say anything for sure with- out knowing what you chose. Nico -- coreboot mailing list: coreboot@coreboot.org https://mail.coreboot.org/mailman/listinfo/coreboot
