PXE not appending kernel parameters

[domenico...@gmail.com]

Hi,
booting via PXE a bare-metal server (UEFI boot), I'm unable to pass kernel arguments  (i.e. cloud-config-url or coreos.autologin) in any way.
This is my efidefault:

default 0
timeout 300

title CoreOS
        root (nd)
        kernel /images/coreos/coreos_production_pxe.vmlinuz
        initrd /images/coreos/coreos_production_pxe_image.cpio.gz
        append cloud-config-url=http://192.168.1.33/coreos/pxe-cloud-config.yml coreos.autologin

CoreOS boots correctly but "append" directive is completely ignored.

Any  suggestion?

Solved specifying parameters on the "kernel" row:

default 0
timeout 300

title CoreOS
        root (nd)

        kernel /images/coreos/coreos_production_pxe.vmlinuz coreos.autologin cloud-config-u
rl=http://192.168.1.33/coreos/pxe-cloud-config.yml
        initrd /images/coreos/coreos_production_pxe_image.cpio.gz
