Hi misc@, I was able to successfully externally flash the BIOS of my Thinkpad T500 with the latest version of Libreboot. I'm really wanting to run full disk encryption on this machine (which boots now with Grub2 as the payload) and I've tried numerous hacks / kludges / clever ideas and I'm still stumped.
The path I was on that felt like it would be closest to successful was to have a MBR partition scheme with OpenBSD in slot 3 at the beginning of the disk and a FAT32 partition in slot 0 at the end of the disk. I copied the kernel there and attempted to get it to use my encrypted disk (sd0a) as my root filesystem (/etc/boot.conf) but obviously that was too late in the boot process and I met with tears. Is there any way I can either leverage Grub2's chainloading or some other clever configuration trick with a second partition to get things to boot something that then opens the softraid0 crypto volume and continues the boot process from there? Sorry if this is a painfully obvious question, but I'd really like to figure it out so that I can write a detailed blog post to help document it for anyone else who wants to try. Thanks, Bryan
