As other people have already pointed out, this is likely to be 
considered a network misconfiguration by your IT guys.  :)

The easiest way to perform iPXE testing might be to start iPXE from a 
USB stick, with an embedded script.  This allows iPXE to use your 
existing DHCP servers only to acquire an IP address; your embedded 
script can then dictate what happens next in the boot process.

If your network is _not_ already using ProxyDHCP, then you could instead 
use dnsmasq to provide a ProxyDHCP service; this would allow you to 
provide chainloaded iPXE (undionly.kpxe) only to your clients, while 
continuing to use your existing DHCP servers to provide IP addresses.

Hope that helps,
