Syslinux - Jan 2014 - Need solution to use environment variable

Hello All.

I need make one configuration for many PXE servers. All of them has different
IP`s.

Will be best is somehow in menu will be possible to have environment variable
with server ip.
Example:

Pxelinux.cfg\Default

UI vesamenu.c32
MENU INCLUDE pxelinux.cfg/graphics.conf
MENU INCLUDE pxelinux.cfg/server.menu
..
Skip 
..
label default
        MENU LABEL ^Custom ISO
        COM32 cmd.c32
        APPEND KERNEL http://SName/sources/common/pxe/memdisk iso raw initrd
http://SName/sources/iso/CustomPE/Custom.iso (not working)

Pxelinux.cfg\server.menu
LABEL SName
10.55.98.127 

Using pxelinux 6.02

Thanks a lot for any help !!!!

No, not directly.

PXELINUX won't be able to utilize HTTP URLs UNLESS you're actually
using lpxelinux.0 OR have gPXE/iPXE active.

If you are able to use HTTP URLs, you should consider passing option
209 and/or option 210 to your booting systems.  It may help to also
encapsulate it so your DHCP server always provides it.

Once you do this, several options open up.

1) just use 210 to change the working directory.
2) Let a web system take care of the content, dynamically or statically.
