I'm assuming this is the right way to ask a general question, but please let me know if it isn't.

I have an "X62" laptop, which is actually an old Thinkpad X61 with a custom motherboard in it. 

This board has an i7-5600u CPU on it, and I was wondering if it was possible to build a version of coreboot for this machine. 

I see an existing mailing list entry in the archive discussing a Chromebook Pixel with the same CPU, so I'm thinking it may be possible unless I'm missing something major.

Since this is a custom motherboard, how would I find out about the Intel Boot Guard and related issues so that I can provide the details for the good folks here?

I'm pretty comfortable around Linux but probably would have trouble building this from scratch.

Thanks in advance!
