CentOS - Sep 2014 - pxebooting

Digging into this, as we rework it, here's a question: assuming the system
being pxebooted is server 1, and the tftp server is server 2, on server 2,
in the menu for pxeboot, is there any way to specify that the image to
boot, and the initrd, are on a server 3? That is,
MENU repoboot
  KERNEL repo://my/repo/images/vmlinuz
  APPEND repo://my/repo/images/initrd.img

(or an IP address, like 192.168.1.13, for the server named repo)?

The gPXE bootloader can fetch files from an arbitrary network host 
using TFTP, NFS, HTTP, etc, but the standard syslinux PXE bootloader 
cannot.

On CentOS 6, the syslinux-nonlinux package includes both. If you 
specify "filename gpxelinux.0" in your DHCP setup, and ensure that the
gpxelinux.0 image is in your tftp root directory, you should be OK.
