Accessing BIOS on Dell server running Ubuntu

I'm running the latest Comet firmware (1.3.0 r1) and everything works fine when using the server, but one of our key use cases is to have the ability to access the BIOS of these machines using the Comets to be able to change the settings. Every time I boot into BIOS using Comet, I get the no HDMI signal detected message. I can hit the esc key to exit and then boot normally and the Ubuntu login screen appears.

I've tried selecting the different resolutions that are provided, but none of them seem to work. I do not know what resolution the BIOS screen is using and I do not know how to create a custom EDID as another post talked about.

Please help me figure this out. :grinning_face:

Do you have other monitors connected to your server? The BIOS is usually only displayed on the primary monitor.
Also, if you are controlling a laptop, usually the BIOS is only output on the integrated screen, not through HDMI

The Comet is the only display device connected to the server and it works great when accessing the OS, but nothing displays (no HDMI detected) when trying to access the BIOS. The monitor icon at the bottom right of the Comet show that as well. The keyboard works as I can hit to go into the BIOS, and then to exit it so that it can boot normally.

I suggest you try 1024x768 or 800x600 resolution in BIOS, which is more common in BIOS.

If it still doesn't work, please export a log to me through the KVM help menu after entering BIOS
