That's a useful size for experimenting with systemd-boot, which expects kernels + initramfs and BLS snippets to all go on the EFI system partition. The Fedora installer's default for the EFI system partition is around 200MiB, and the most I've seen Fedora's bootloaders use is ~14MiB.
I'm going to look into alternatives since I seem to be having such little success with the default. I'll investigate sd-boot.
Some firmware only boot CD's with CSM. Other firmware, you must use the built-in boot manager, which shows what firmware type will be presented when booting the CD, i.e. you'll see the CD listed twice. Once with UEFI listed; and also without or possibly with the word "Legacy"
Solved this at least. If I edit the boot line, and knock off quiet, I see something close to "EFI stub: Booting UEFI in secure mode", so I know that I'm booting in UEFI now.
After you boot installation media you can check what firmware is presented with # efibootmgr
If entries appear, it's UEFI. If an error appears, it's CSM/BIOS. And if it's CSM/BIOS then defining a /boot/efi mount point is invalid. If you want a UEFI installation, it's mandatory that you figure out a way to boot the install media in UEFI mode. Even if it means you have to create a USB stick, and must abandon CD booting.
This is a handy way to check and confirm. Good for future reference. But, as I mentioned in other posts, on hold for now.
