That's what contains the boot parameters. To modify the CD you use the command mentioned in the comment above "make EMBEDDED_IMAGE=/path/to/script.gpxe" where the EMBEDDED_IMAGE value is the path to the script. If you rerun that it will overwrite any existing images with the new one. Alternatively you could do what I do, which is host a boot script on a webserver and tell all clients to go to that once they have an IP. This is what I've done (and will be talking about it in Part 3 when I get around to writing it). This way you just alter the script on the webserver and it will be used from then on by all your clients. Hope this answers your questions. Rick Hi Rene,

I had just started with the same problem. I have 2 questions: The only piece that seems to be missing is the nbdroot=xxx.xxx.xxx.xxx:2000 In normal dhcp operation, where does it get this value. In my case the normal DHCP works, it is just when I get to a location that I can not modify the DHCP that I have the same problem as you do. The second is how do you modify the (in my case a cdrom ) gxeboot boot to do all this automatically. Thanks, great write up and keep up the good work.
