[ipxe-devel] Build ipxe.efi with IMAGE_BZIMAGE fail

[Ковалёв Сергей]

Hello.

I have tried to boot linux kernel by providing bzImage from custom build to iPXE. But it failes with error "Could not select: Exec format error (http://ipxe.org/2e008081)". In iPXE header I could see line "Features: DNS HTTP iSCSI TFTP SRP AoE EFI Menu".

So I have tried to enable bzImage support in iPXE. But faced with error:

Could someone give me an advice?

P.S. I have successfully loaded kernel from Fedora 23 (file vmlinuz-4.4.9-300.fc23.x86_64) but I don't why.
