Comment # 6 on bug 1172292 from Neil Rickert

I'll note that I have been experimenting with this since 2018.  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-efi/

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.
