I got a bit of a different effect after trying without any monitor at all.
In the BIOS all of a sudden the Internal Video showed up in the settings
with options to make it primary and to always enable or disable.

Unfortunately still no joy. With every possible combination of primary or
not, enabled or not, monitor connector or not, there is still no boot
without the external card attached. It boots in every combination with the
external card attached.

Something else in the document leads me to belive that it may be a EDID
problem. It points out that EDID is used to set the video modes. I was
testing with an old monitor. I tried with a newer Acer P235H, but still no
luck.
