[syslinux] Is efiboot.img required?

How the hell does it know that it is "Syslinux" ?
The same file content does not cause that name if it
is presented under the default name.
Does EFI just guess "Syslinux" from "syslinux.efi" ?

I really cannot read this behavior from UEFI 2.4 specs.
There may be a NVRAM variable which tells the file path,
or there may be the fallback names which are to be used
on removable media or in case that the path in the variable
is empty.


Have a nice day :)
