Syslinux - May 2020 - PXEBOOT - chainload different syslinux version

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?

Try using pxechn.c32 from the same version that you are booting with (6.04..., 
+ libutil.c32 + libcom32.c32 from the same version) in order to chainload to a 
different network boot program.

Search the Syslinux wiki for pxechn.c32, and the official docs.

Ady.

Hi,

Thanks, worked ok with pxechn.c32:

KERNEL boot/isolinux/pxechn.c32
APPEND xxx.xxx.xxx.xxx::/isolinux_3.86/pxelinux.0 -p /isolinux_3.86/
