You need to have some patience. Your first post is only about an hour old.
You have ONLY posted three times and this thread is the only one that has a response so I am not sure what you mean about getting messages that don't make sense.
We are all volunteers here and it is Sunday night in North America and the middle of the night in Europe. I addition to that, you are not asking about any specific issue you are having.
I suggest you read the manual for your computer.
If you don't understand the settings in your BIOS then perhaps you shouldn't be making changes. Also, you must SAVE changes on exiting the BIOS.
