Qubes 4.0 won't boot via coreboot grub rescue

[Tai...@gmx.com]

I try the usual syslinux_configfile but I get an "out of memory" error
how am I to do this? ideas?

Can you step through what you are trying to do and where the error
appears? Not sure I'm following.

Sure :D

I wish to install qubes 4.0 via the coreboot grub payload.

So I try to boot qubes 4.0 DVD via the grub coreboot payload which
provides one with a grub-rescue console, normally the command
"syslinux_configfile (ahci1)/isolinux/isolinux.cfg" or what not will
launch the iso as normal but instead I receive an out of memory error
and for some reason the grub.cfg included in the isolinux folder doesn't
work either.

Thanks, following now! I thought someone had replied to
https://www.mail-archive.com/qubes...@googlegroups.com/msg20818.html
with a way to do it, but that thread appears to be broken. If you're in a
hurry, suggest trying Seabios to get it to install then switching to grub.

I don't know which device you're using but I have flashed Coreboot with SeaBIOS on my X230 and have also documented how to do so. I was
also thinking about using GRUB but there were many side effects which someone mentioned in a Qubes posting. I think one of them was
related to updating dom0 and thereof I choose simplicity over security. Using SeaBIOS was good enough for me, the only nice thing about
using Coreboot + Grub is (as far as I understand) that we can run an encrypted boot, which might offer a better protection against evil
maid attacks.

My idea against Evil Maid attacks was to run somthing like AIDE (file fingerprinting) on /boot and to verify.
I think this is also the idea of the Anti Evil Maid approach in Qubes.

But to be honest, the risk that someone attacks me via evil maid is not very high for me or in other words "reasonable unlikely" :-)

If you get Coreboot+GRUB on qubes fixed I am interesting in hearing how this works during daily use.

One could try Qubreboot, however, ive never tested it. Alternativly,
install it with grubentry which boots the iso. Havent done yet either,
will try these days.
