Thanks for the packet trace, which seems to show that iPXE isn't receiving the 
replies from your DHCP server.  (iPXE uses the DHCP "seconds elapsed" field to 
indicate some of the DHCP client state: bit 1 of this field is never set in any 
of the DHCPDISCOVER packets, which tells us that iPXE has not received any 

Two things I would try, both involving the iPXE command line 

a) try running the "dhcp" command at the command line and, after it fails with 
the same "Connection timed out" error message, run the "ifstat" command 

b) try setting a static IP address as described on the error page 
(http://ipxe.org/4c106035), and see if you can ping it from the DHCP server.
