Time for another update on my work for UEFI improvements in Jessie!
I've spent more time on the integration of 32-bit grub-efi with a 64-bit Debian system, and just published a new test image on pettersson. I've added:
These remove the manual steps that were necessary for a 64-bit installation with the previous build. I've just used this exact image (and a network mirror) to install a fully-functional 64-bit Gnome system on the X205TA, simply by selecting "64-bit install" from the GRUB menu and following prompts. Yay! Visit http://cdimage.debian.org/cdimage/unofficial/efi-development/jessie-upload3/ to download and test the image.
Now, there's no guarantee that the kernel patch I've submitted to the linux-efi folks will be accepted in its current form, and even if it is I'll have to get it and the other code I've written accepted into the various packages and then into Jessie! But for now this image should work just fine for Bay Trail folks I hope!
WARNING: this CD is provided for testing only. Use at your own risk! If you have appropriate (U)EFI hardware, please try this image and let me know how you get on, via the debian-cd and debian-boot mailing lists.
For now, I'm going to pause development here. The core code I'm using to make these images is all in the debian-cd and d-i repos, and I'll push the other patches once I know they'll work with the kernel. But I've got a slew of other things that I need to work on in the next few weeks, in no particular order:
I'm currently not planning to make all of Debian's amd64 images bootable using 32-bit UEFI like this image - I'm happy to leave this as just an option for our multi-arch i386/amd64 images (netinst or DVD only). I think that's a reasonable compromise here, and it's also the easiest thing for me to do with the current debian-cd build system.
Finally, apologies if you've asked me questions about the earlier images in this series and I've not responded yet. Fixing that ASAP!
