PXE booting a syslinux Kernel

Question

I got a small Problem with my Ubuntu 14.04.3 LTS Server.
At first i've installed this packages on my server : dhcp3-server , tftpd-hpa , nfs-kernel-server and syslinux.
Everything runs fine and i've already made a working memtest boot with a complete menu.

My Nfs Folder is /nfsroot/. My tftp Folder is /var/lib/tftpboot/.
Furthermore there is the config Folder /var/lib/tftpboot/pxelinux.cfg and the default File /var/lib/tftpboot/pxelinux.cfg/default.

My Boot Menu is made with menu.c32.

My Problem is now that i want to boot another syslinux kernel with my PXE-server. I want to boot syslinux with every Computer in my network. The Problem is that i dont know how the Append line for the menu.c32 has to look like and what i have to download additionally. I've already downloaded the latest syslinux Kernel (6.03) to the root of my Server,

A tutorial for that would be nice. Pls help me :(

• You can add new menu entry to /var/lib/tftpboot/pxelinux.cfg/default and Change DEFAULT to point to the new kernel entry.

  DEFAULT partmagic 
  
  LABEL partmagic 
      MENU LABEL PartMagic 4.5 
      KERNEL pmagic/bzimage 
      APPEND initrd=pmagic/initramfs edd=off noapic load_ramdisk=1 prompt_ramdisk=0 rw vga=791 sleep=10 loglevel=0 keymap=us livemedia
  

• If you are using a complicated menu template, try search for menu text:

  grep -nir `LABEL` /var/lib/tftpboot/
  

  Then append the new menu entry where you find the old one.

• Concerning manual, see /usr/share/doc/syslinux-common/txt/menu.txt.gz.

  There are many other manuals with nice examples in /usr/share/doc/syslinux-common/.
