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.
