Hi all,
I was successful in unlocking my Lenovo ThinkStation P320 UEFI which is Aptio V, mainly because of Serial Console Port Redirection, that enables me to remove the graphics card and use the system as headless server.
Using uefipatch I edited IFR. With a custom python script I modified StdDefaults>Setup to enable Serial Console Port Redirection by default. This all works fine.
What doesn't work is the console redirection:
With graphics card I see the POST screen and can react to errors like "Checksum error. F1 to enter setup, F2 to resume."
There is no need for attaching a monitor. The card just has to be inserted.

Without graphics card I only get some of the output and the system does not react to F1/F2/<whatever>.

Without graphics card, when there is no error, I am even able to enter setup. So there must be a bug or something else in error handling...

I *really* want to remove the graphics card to save about 13W of useless power but I need to be able to react to errors etc.
Is there anyone with an idea about what is wrong here and how I can solve that?
Best regards
Michael
