ipxe script load but not proceed

[Michaelzxm]

Hi

I'm trying to user ipxe.lkrn in menu.c32 of pxelinux.0, the config menu like below:

===========
Title ipxe
kernel ipxe.lkrn
initrd test.ipxe
===========

When I select this menu, then the lkrn and script was loaded successfully, but seem the script was not proceed, then just go back to pxelinux.0 and the previous menu appears again.

script like:

======
#!ipxe
dhcp
chain https://xxxxx/test
======

I also tried append the script as kernel option " kernel ipxe.lkrn dhcp && chain https://xxxxx/test". also didn't work.

The ipxe.lkrn is customized by VMware to deploy ESXi server, and no "read" and "menu" option within it, so I cannot use the ipxe's native menu.

Any help will be great appreciated, this problem has troubled me a few days....
