Here is the GRUB2 entry:

menuentry "iPXE"{
search --no-floppy --set=root -f /live/ipxe.efi
chainloader /live/ipxe.efi + 1
}

I have placed a plain text file script at /live/script.ipxe but it doesn't see the script. What do I have to do?

UEFI iPXE does not currently have the ability to load images (e.g. scripts) from a local UEFI filesystem. This is planned to be implemented. In the meantime, you'll have to build ipxe.efi with your script embedded (via the EMBED=... build option).
