coreboot rom file

[El Nerdo]

Greetings!

I was wondering if anyone has the coreboot romfile with the seabios payload
already made for the Acer C7 chromebook. I would like to flash mine with
it. If not, then I will attempt to make my own in Linux. I know that there
might be a problem making the coreboot rom in certain linux distros so do
you know of a distro that has a good compatibility in order to achieve this
build? Final question, once I have a coreboot rom how to I start the
flashrom utility in chome os dev mode? What are the commands to flash it?

Thanks for any help.
