grub2 support for x86_64 and aarch64
|
|
====================================
|
|
|
|
xCAT 2.17 enables grub2 boot support for x86_64 and aarch64 but does not ship the necessary grub2 binaries for both architectures.
|
|
If you want to use grub2 for x86_64 or aarch64 you need to download the binaries from some EL OS repository.
|
|
|
|
#. Download files from an BaseOS EL repository mirror
|
|
|
|
For EL these files are named ``grubx64.efi`` (x86_64) and ``grubaa64.efi`` (aarch64) and usually in ``BaseOS/<arch>/os/EFI/BOOT``.
|
|
For very recent hardware you might need to use a newer grub version. Therefore, it's recommended to use a binary from the latest operationg system release available.
|
|
You can use Red Hat Enterprise Linux, AlmaLinux, Rocky Linux or even Fedora repositories to download the grub files.
|
|
|
|
#. Copy downloaded files to ``/tftpboot/boot/grub2``:
|
|
|
|
* x86_64: ``/tftpboot/boot/grub2/grub2.aarch64``
|
|
* aarch64: ``/tftpboot/boot/grub2/grub2.x86_64``
