[Bug 1172292] New: Support for 64-bot processors on motherboards with 32-bit UEFI
http://bugzilla.opensuse.org/show_bug.cgi?id=1172292 Bug ID: 1172292 Summary: Support for 64-bot processors on motherboards with 32-bit UEFI Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: 64bit OS: openSUSE Factory Status: NEW Severity: Enhancement Priority: P5 - None Component: Installation Assignee: yast2-maintainers@suse.de Reporter: jens@krieger-juhnke.de QA Contact: jsrain@suse.com Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0 Build Identifier: On some devices (In my case a Lenovo Ideapad 100s-11iby) have 64 bit processors, but a 32-bit UEFI, so the 64-bit installation mediums are not recognized by it. Reproducible: Always Steps to Reproduce: 1. Grab a device with a 64-bit processor and a 32-bit UEFI 2. Try to boot from a 64-bit installation medium Actual Results: The installation medium is not listed in the boot menu. Expected Results: The installation medium is listed correctly, just like on a machine with a 64-bit UEFI. I did a bit of research, and found out the following: Fedora has natively supported 32-bit UEFI for 64 bit installs since Fedora 27. There seems to be a a workaround, but this is not very practical for new users, which adds a file from Github (https://github.com/hirotakaster/baytail-bootia32.efi) to the installation medium. -- You are receiving this mail because: You are on the CC list for the bug.

My experiments are in a KVM virtual machine with ovmf firmware. I described some of my attempts here: https://nwrickert2.wordpress.com/2018/11/28/opensuse-leap-15-0-and-32-bit-ef... I currently have both Tumbleweed and Leap 15.2 running this way. If you want help for installing, then open a new topic at forums.opensuse.org and I will assist. My current install method would easier than in that earlier blog post, but does require some linux command line steps. With regard to possibly providing install support, I can probably help there too with testing and with perhaps using my experience. With current install media, my method would be: 1: Use the DVD installer, and copy that to a USB flash drive; 2: Create a new larger EFI partition on that flash drive, and change the original partition type to FAT16 (so that there is only 1 EFI partition). 3: Copy the original EFI partition to the new one (file/directory tree copy, not binary copy. This is so that 64-bit EFI installs can still be done. 4: Modify that EFI partition by installing support for grub2-i386-efi booting. Obviously that's missing detail. After those changes, you can install. But to boot the newly installed system, you would need to install grub2-i386-efi, and manually run grub2-install to set it up. -- You are receiving this mail because: You are on the CC list for the bug.

I did the installation by accessing the installation media through Ubuntu grub command line (by manually grubconf to grub.cfg of opensuse installtion media ). yh so , Ubuntu and grub was already present in my system and i just installed opensuse through Ubuntu's Grub . The installation media was created using dd (Etcher works fine) . HERE , You don't have to copy bootia32.efi to installation media as the booting is done by Ubuntu's already installed 32 bit Grub . During installation use the existing /boot partition to install opensuse and don't create a new one !!!!! -- You are receiving this mail because: You are on the CC list for the bug.

The bad news is that there is still no installer support (for Leap or for Tumbleweed). -- You are receiving this mail because: You are on the CC list for the bug.
