iPXE fails to boot anything

[ArneLovius]

My parted magic looks like this

Code:

:parted-magic
set base-url ${boot-url}/parted-magic
cpuid --ext 29 && set arch bzImage64 || set arch bzImage
kernel  ${base-url}/${arch}
initrd  ${base-url}/initrd.img
imgargs ${arch} edd=off noapic load_ramdisk=1 prompt_ramdisk=0 rw vga=791 sleep=0 loglevel=0 keymap=us
boot || goto failed
goto start
