Re: [coreboot] new, need help and whatnot
I ended up using a raspberry pi before i even read David's reply, went on without an itch. I did see a light go green on the board though. Maybe i was lucky. Will remember to put a temporary jumper on the reset switch header next time.

I already ordered a Bus Pirate, and i already received my soic clips, so all is not lost. i have an Intel S3420GPLC Server Motherboard. Specs are here: http://download.intel.com/support/motherboards/server/s3420gp/sb/s3420gp_tps_r2_4.pdf msrtool.log is empty, got a core dump. rom.bin is here: https://docs.google.com/file/d/0Bx4lQySb-zrCT0RmVlB4d2pGa00/edit?usp=sharing Thankfully the rom looks complete so i should be able to unbrick the thing.. The board has an ME and a BMC, and yes i know that's probably why i ended up with a brick. I mean i could see the big warning sign in the docs, i just, well, wanted to learn something... :P There is a recovery bios on the thing, but it does not seems to work right now... ;) To think that i'm actually laughing about it is really something... :) i hope you guys can use these logs(see attached files).. :) Sounds like you've already identified the problem and are well on your way to recovering your board. There are a few caveats though: - Some boards do not isolate the ROM circuitry well, and your programmer (Bus Pirate) may backpower motherboard components such as the ME, which will attempt to boot and interfere with flashrom. So you may need to hold the board in reset while you flash using the Bus Pirate in order for it to be successful. - It is possible that when you read the ROM content earlier on that the ME interfered by changing the SPI address and doing something while flashrom was running. If that happened, your image may be corrupt and will need to get a new firmware image from Intel's website and flash it instead.
