= System Wide Change: 32 bit UEFI Support = https://fedoraproject.org/wiki/Changes/32BitUefiSupport
Change owner(s): Peter Jones pjones@redhat.com
Some x86 systems ship with a 64 bit CPU, but 32 bit UEFI firmware. It is possible to use a 32 bit UEFI grub build to boot a 64 bit kernel and distribution on these systems. So far this setup has not been supported in Fedora. This feature is about adding support for installing and booting Fedora on this hardware.
== Detailed Description == To add support for booting Fedora x86_64 on x86 systems with 32 bit UEFI firmware a number of (small) changes to grub, various EFI related userspace tools and anaconda are necessary. See Scope for more details.
== Scope == * Proposal owners: ** The x86_64 grub2 packages will need to include an extra grub build, next to the current classic BIOS and 64 bit UEFI build a new 32 bit UEFI build will be added to the x86_64 packages. ** This new grub will need to be added to the various x86_64 boot media ** A few EFI userspace utilities need to be updated to work with 32 bit x86 UEFI ** The installer (anaconda) needs some changes to the bootloader installation code to install the 32 bit UEFI grub binary
* Other developers:
No changes are necessary outside of the affected packages
* Release engineering: [1] ** List of deliverables: This feature should be enabled on all non cloud/container x86_64 images
* Policies and guidelines: N/A (not needed for this Change)
* Trademark approval: N/A (not needed for this Change)
