Setup & Installation / Re: No mouse/keyboard after BIOS update
« on: November 11, 2024, 10:44:40 pm »
Hello Per.
Just to know a little bit more I was checking a Simulator of your BIOS
I guess is this one (text mode only).
- https://download.lenovo.com/bsco/index.html#/textsimulator/ThinkStation%20P520%20(30BE,30BF,30BQ)
What is the two things? "XHCI Hand-off" and "above 4G decoding" the things that did the trick? or just one of those?
I have this hardware report on the wiki:
- https://www.os2world.com/wiki/index.php?title=Lenovo_ThinkStation_P520
It says "enable "CSM" and disable "Above 4G Decoding"".
I don't remember who reported that on 2020, was it you?
Did the BIOS updated enabled back the "Above 4G Decoding"?
Regards
