Boot Configuration - EFI Boot File

[dimitrirodis]

Under /index.html#vtoy_settings , there are multiple options for EFI Boot File:

snponly.efi
snp.efi
ipxe.efi


..What are each of these, and why would we use each one?

I'd also appreciate a documentation about this - can't find any explanation what these options mean.
