* EFI bootloader files need to be in /EFI/Boot in order to be portable * EFI bootloader files need to be in /EFI/Boot on portable media to get picked up, I've retained the mixture of line endings in these files as requested (https://github.com/Tomas-M/linux-live/pull/84#issuecomment-623150025) * Again, these files need to be in /EFI/Boot to be portable * There will be an EFI structure under boot that is consistent with what EFI requires. Additionally, the syslinux build for EFI doesn't support the vesamenu properly at currently so we have to use the non-vesa menu * EFI executables from syslinux 6.03 * to support the VESA menu we need additional files * These are the syslinux 6.04pre-1 files that support vesamenu on EFI. All other builds are broken and all the post pre-1 builds are known to be unreliable according to the syslinux mailing list
