The documentation for this all is a bit all over the place. I tried to document it all in the gentoo wiki when I got things working from help from this ML. https://wiki.gentoo.org/wiki/Trusted_Boot > On 08/10/2016 07:26 PM, Brian E Luckau wrote: > > Thank you for the tips.

Tboot isnt a UEFI aware thing, so you still need to have some compat stuff turned on. In my Thinkpad T440s, I have to enable "CSM" otherwise it just dies. With CSM enabled, UEFI+grub2+multiboot2 works fine tho. https://wiki.gentoo.org/wiki/Trusted_Boot#BIOS_configuration Another thing you can try, if it is resetting and you want to be sure that its happening after tboot, put a while(1) {} in tboot right before the jump to the kernel and see if it hangs. You can also boot into the UEFI shell after a reset and run "mem fed30030 4" and see what the error code was set to when it died. -- Jason > > > > I'm accustomed to the system booting regardless of whether you have > > the hardware, bios, etc. for it.
