How boot iPXE script over pxelinux ?

[Gelip]

I have own configured server TFTPD32 with DHCP and TFTP (pxelinux.0 + menu default). Now I learned that HTTP protocol is faster than TFTP to load ISO images. I want change loading ISO images to HTTP protocol in file default. I make script for boot over HTTP protocol:

Code:

#!ipxe
initrd http://192.168.xxx.xxx:port/mxp14.iso
chain memdisk iso

How to do it?

Code:

LABEL image
MENU LABEL Boot ISO over HTTP
kernel mxp14.ipxe

but this not working :-(

I know that this working in menu.ipxe booted from TFTP like this:

Code:

:image
echo ISO over HTTP
chain mxp14.ipxe
goto start

but i want this with menu default. Is this is possible?

If this is not possible please help me how boot ISO over HTTP automatic other way.
