Ok, discovered one thing, in the Advanced Settings, to go and disable the Plug and Play control, there is ROM Shadowing
I noticed that except the first three options, I can change everything.
Here almost everything is disabled, except the last entry which is enabled, it says: (BIOS for video adapter).
Isn't that the option to disable the integrated card?
Isn't it better for me to enable everything, since everything is disabled?
