WARNING!
Updating your firmware has a risk of bricking the machine.
You have been warned, and do so at your own risk.
---

this assumes that you already have coreboot running and are updating it.

put coreboot.rom in the flashrom directory

a flashrom executable is already compiled for convenience.
so if you don't want to compile, just make sure it has execute permission:
chmod +x ./flashrom

or if you want to compile it again:
make clean
make

---

with coreboot.rom in the flashrom directory, do this:
sudo ./flashrom -p internal -w coreboot.rom
--
or this command, if 3 flash chips are detected (in the case of X60's with the macronix flashchip):
sudo ./flashrom -p internal -w coreboot.rom -c "MX25L1605D/MX25L1608D"

shut down your machine after it says VERIFIED.


then wait a few secs, turn on and you see grub.
(note: if it fails to load but the screen turns on: remove battery/charger then reconnect them and boot up)
