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.

I seem to recall this question was also asked on the Google+ community, and the solution was to run the console command to get a VESA resolution instead of text mode.

Yes.

For some reason Cedarview based chipsets do not like BIOS video mode. iPXE has to be compiled with VESA support, and the console command must be run to enable it, then menus can be displayed.

Thanks!
