I'm running a FOG server and added many hacks to my pxe menu but now I want to add DRBL Live but it doesn't work

I tried that with this pxe configuration

LABEL fog.drbl

    MENU PASSWD $1$b1E5ld/w$nRekAlrkmtRfofb4ZJC7L1

    kernel fog/drbl/live/vmlinuz boot=live config nomodeset vga=785 ip=frommedia nosplash

    append initrd=fog/drbl/live/initrd.img

    MENU LABEL DRBL Live

    TEXT HELP

    Start Live DRBL server with clonezilla live &  clonezilla server options

    ENDTEXT

I get initrd.img and vmlinuz from the iso of DRBL Live and the parameters from the grub configurations in there $DRBLiso/EFI/boot/grub.cfg.

When booting to DRBL option I get the following errors :

dprobe: module unknown not found in modules.dep

dprobe: module unknown not found in modules.dep

dprobe: module unknown not found in modules.dep

dprobe: module unknown not found in modules.dep

dprobe: module unknown not found in modules.dep

dprobe: module unknown not found in modules.dep

dprobe: module unknown not found in modules.dep

dprobe: module unknown not found in modules.dep

dprobe: module swap not found in modules.dep

can anyone see what's wrong here ?
