The most common iPXE boot loaders are undionly.kpxe (for bios) and snp.efi/snponly.efi (for usefi). Just be aware you can not boot a bios bootloader (undionly.kpxe) on a uefi system unless CSM is enabled. But then CSM would boot in bios mode. The same is the case for snp.efi, it will not boot on a bios based computer.
