[syslinux] PXEBOOT - chainload different syslinux version

[Maverick]

Hi,

I would like to chainload syslinux 3.86 after booting from pxelinux of
syslinux 6.04 is it possible?

I was checking chain.c32, but i was not very successful so far.

on my tftproot  dir i has this:

pxelinux.0
boot/isolinux/
pxelinux.cfg/
isolinux_3.86/pxelinux.0
isolinux_3.86/boot/isolinux/
isolinux_3.86/pxelinux.cfg/

Does anyone know how i can, after booting from the tftproot pxelinux.0
(syslinux 6.04), chainload isolinux_3.86/pxelinux.0 and make
isolinux_3.86/ the working dir?
