    EFI Debian CDs, step 4: i386 support

    Continuing on from my third EFI progress report...

    I've added some i386 EFI support in debian-cd and built new images. Alongside a new amd64 image, we now have an i386 image and a mixed image which should hopefully boot and work on both 32-bit and 64-bit machines. The i386 support is more experimental at this point, and it's more difficult for me to test due to a lack of physical hardware. If you've got an older 32-bit EFI machine, this might work for you...

    Grab the images from if you'd like to help test. Please do, and let me know via debian-boot/debian-cd how you get on.

    As previously, the "bits" subdirectory contains all the tweaked d-i packages I've played with, in both source and binary form. My debian-cd changes are still in my branch but are just about ready for merging I think. I've posted my full set of d-i patches to the debian-boot list for review now, and hopefully we'll be able to get those changes merged in after the Wheezy d-i beta 2 build is done. Full speed ahead for EFI in beta 3!

    I tried the debian-wheezy-amd64-efi-test4.iso on a Mac Mini 2011 using a USB stick, and it looks like it's in good shape. The only problem I had was that eventually, my install wouldn't boot, but I might have forgotten to set the bootable flag. But other than that, I could boot to the installer, and the install process kept going without hitting any errors. One little note: I saw two volumes in Mac's EFI when booting it while pressing the option key; I think they were labeled "Windows" and "EFI". I only tried booting from the one labeled "Windows" and it worked.

    However, what I'm really interested in is trying GNU/kFreeBSD. How much of this EFI related work will transpose easily to GNU/kFreeBSD?
