Hi group,

does somebody know the correct options for 
pxe booting  Ubuntu live

I tried many versions of

LABEL Ubuntu
  MENU LABEL Ubuntu Live
  KERNEL ubuntu/vmlinuz
  INITRD ubuntu/initrd.lz
  APPEND debug dodhcp fetch=http://a.b.c.d/tftp/ubuntu/filesystem.squashfs
toram

Also no success with memdisk
LABEL UbuntuISO
  MENU LABEL Ubuntu Live ISO
  KERNEL memdisk
  INITRD ubuntu/ubuntu.iso
  APPEND iso raw

Parted Magic works fine with kernel/initrd  as  with memdisk/iso (with
pmagic menu then)
LABEL PMagicISO
  MENU LABEL Parted Magic ISO
  KERNEL memdisk
  INITRD pmagic/pmagic.iso
  APPEND iso

LABEL PMagic
  MENU LABEL Parted Magic
  KERNEL pmagic/bzImage
  INITRD pmagic/initrd.img
