Hi everyone Since here are the most skilled professions I've seeing I believe someone can help me. I have a Lenovo x230, and I'll would like to install coreboot in it to start to understand how it works, and in future start to help the community, as soon as I have the knowledge for that. Last week I did a test that makes my progress stop. Just for fun, and to check how the commercial bios works, I connected a postcard on the wireless slot (as far as I know this is a pcie slot). I already did that with other notebooks I have and nothing wrong happened. The problem is that this time, with this x230, after I connected the postcard and turned the system on, the system stopped to boot. And the post card does not stop at a specific post code. What happens now, is that every time I turn the system on, the battery led blinks 3 times, being two blinks followed by a 1 second stop and after that the last blink, and the system reboots. The post card I'm using is this: https://www.ebay.com/itm/3in1-Mini-PCI-E-PCI-LPC-Tester-PC-Desktop-Diagnosti... So my questions are: -Does someone believe this postcard could have bricked the system? (Why?) -Any idea about how to solve that? My next test will be to write a coreboot build at this system using buspirate, but since I'll only have time for this next week, I would like to have some things to think about, this is why I sent this e-mail before doing the coreboot flash test. Any comment will be helpful. Thanks and Regards Rafael R. Machado
