iPXE Menu loses video

[caseyatherton]

I have an iPXE menu script set up that works great on most hardware. However, on certain hardware, specifically anything with an Intel Cedarview based chipset, it fails. When the script gets to the menu portion ("choose" command), the screen goes blank and the system becomes unresponsive. I've also confirmed the same symptom by simply entering the "config" command.

At first, I thought the problem was that the menu was outputting only to the LVDS connector, a known issue with Cedarview on Linux. However, I also don't get any output on the serial or syslog consoles.

Any advice on this issue would be appreciated.
