1) Script on the forum post at the link I've included in this thread<br>
2) I didn't build iPXE with the script, I'm just trying to use undionly.kpxe with the script<br>
3) Don't know...not at a place to check at the moment, but I will when I return to the office<br>

Good day, Ty.<br>
<br>
1. What script are you using?<br>
<br>
2. How did you build iPXE with that script?<br>
<br>
3. What version does the iPXE you built report itself to be?<br>
<br>

Does anyone have any idea why such simple functions are broken? It's easy to test...just shut down the DHCP server on your physical network segment and watch as a script that is supposed to retry the DHCP request...doesn't.<br>
It exits the script every time.<br>

Did a fresh git sync and compiled undionly.kpxe. Tried it, but got the same results.<br>

I don't think so, at least it's not ancient. I did a git checkout only a month ago. I'll do a fresh download and see if that makes a difference, though.<br>

How recent is your iPXE version?<br>
<br>
Could it be ancient enough to simply not support the new scripting features yet? It's always a good idea to try the most recent version anyway.<br>
