loading kernel with secure boot

[Victor]

Thanks for the hint.
The Problem is the kernel is not recognized as efi file due to security police (http://ipxe.org/err/7f04819a), so this explains why this is only happening with secure boot.
I copied the kernel on my EFI partition and used the efi shell to start it. It worked without a problem.

The script I'm running is:

Code:

#!ipxe
dhcp
initrd nfs://"server_ip":/data/tftp/zdv-live-secure/tftpboot/live/initrd.img
chain nfs://"server_ip":/data/tftp/zdv-live-secure/tftpboot/live/vmlinuz initrd=initrd.img boot=live components nosplash netboot=nfs nfsroot="server_ip":/data/tftp/zdv-live/zdv-live locales=de_DE.UTF-8,en_US.UTF8 keyboard-layouts=de,us noautologin timezone=Europe/Berlin
boot

The hole process uses shim and a MOK keys to verify the files.
