[syslinux] Booting with PXE on Intel Pro GT

[J.H.]

This looks like you've made this WAY more complex and insane than it's
needed to be.  I would suggest you read through
http://syslinux.zytor.com/pxe.php as it has an the basic framework you
will need to work with.  Now taking that and what you have and moving
forward you probably need something akin to this:

----------
dhcp.conf:
----------
ddns-update-style none;
# Definition of PXE-specific options
allow booting;
allow bootp;
subnet 10.10.10.0 netmask 255.255.255.0 {
	filename "pxelinux.0";
	next-server 10.10.10.1;

	deny unknown clients;

	host node1 {
		hardware ethernet 00:50:DA:B5:2A:3D;
		fixed-address 10.10.10.5;
	}
}
