Any news on that X220 support mentioned? I have, and use, an X220 for all of my personal computing. How would one flash this and what would improve/break? I've heard things about different mini PCIe cards working after flashing to different types of BIOSs.

You'd probably flash it using flashrom, just like non-blobless (blobfull?) coreboot. BTW, a really interesting coreboot distribution is https://github.com/osresearch/heads https://github.com/osresearch/heads (focused on boot security)

Yeah, I have an X230T (X230, tablet version.) How likely is it that any X220 supported stuff would work on the X230?

  Funily enough I have an X230T too and I'd like to switch over to that. I cant get my battery life on my X230T to match my X220 at all. Any tips for this? I can't wait to have a note-taking pen tablet laptop thing, battery life is just a big factor for me. I'm a college student and need to be able to run my laptop from 8AM to 12PM. X220 works great for that. X230T is not there yet for me.

I don't know about the X220, but I can tell you about my experiences with setting up an X200 I bought off ebay. Its not quite trivial.. You need to get access to the SPI flash chip on the mother board. They sell some fancy little clips to attach wires, but I just had one of the hardware guys at work tac some wires directly to the chip. Then I used a raspberry pi to flash the image across using their tools. Maybe I had a dodgy connection, but it took several tries of flashing to get it to work correctly. Once installed it isn't much of a bios. It is mostly just GRUB, you lose all the existing bios settings completely. It lets you boot from different images and thats about it. It does work well once it's set up though. Here's a few low quality photos of the procedure. http://imgur.com/a/zAQRl http://imgur.com/a/zAQRl
