I tried wget 
https://www.kernel.org/pub/linux/utils/boot/syslinux/syslinux-5.00.tar.gz 
and extract all the modules it asked for.

I ended up with Error: An undefined symbol was referenced.

So I guess there needs to be some compilation against libraries in order 
to get pxechn.c32

I use CentOS 7 that shipped a 4.x version of syslinux. I have no idea 
why this version is so old.

Do you now where to get an free RPM of syslinux with pxechn.c32  , I 
think I found a version from Dag W. but it needs a password.
