There is a batch of black CH341A s which are giving 5V instead of 3.3V - which is dangerous for flashing - so please try to get a green CH341A. There are plenty of them available from AliExpress / China. And about the test clips, you can find a small review of different test clips here http://dangerousprototypes.com/docs/Flashing_a_BIOS_chip_with_Bus_Pirate (double check that your BIOS chip is SOIC8 shape, otherwise that will be useless for you). The build is not difficult, there are plenty of manuals available online + a helpful community as you see ;-)

Thank you for reply.
I found CH341A and SOIC8. But CH341A is not green. It is black edition. Doesn't it work?
And build is not difficult?

Usually, to flash a coreboot to a coreboot-supported laptop, you need to build a coreboot.rom firmware image for this laptop's model - and then, use the flashrom-supported programmer (i.e. a green PCB CH341A to simplify the process and reduce the costs - it's much much cheaper and simpler than RPi) together with a test clip which is compatible with the laptop's BIOS chip shape (i.e. SOIC8). More helpful instructions could be found online for your specific model; x230 is popular enough and there are a lot of guides

Hello.
I would like to install Coreboot on my Lenovo x230, but I don't know how to do that. Please tell me how to do it. I have done a lot of research on my own, but I just can't figure it out. I am not a computer educated person.
I don't have a rasberry pie. Do I need it?
And what are skulls and heads, and what is the difference between them and coreboot?
