This is the howto: http://www.howtoforge.com/ubuntu_pxe_install_server I have two questions, 1) Is it possible to set this up without setting the Ubuntu box as the DHCP server, and without access to the DHCP server? It says to modify the existing DHCP server by adding lines of code, my DHCP server is a router, I can't add code, at least not in any way I know of. I can't setup Ubuntu as the DHCP server, because I use WiFi, and it seems like a lot of trouble just to setup PXE booting. 2) Is it possible to set this up on Feisty? Every Ubuntu machine I have is Feisty, I tried it on one (I disabled the DHCP on the router since I have static IPs and no one else was home, the don't have static IPs, I was able to do this I can't anymore), and the PXE boot said something like "Error 32 TFTP timeout". Any help would be appreciated, thanks in advance.
