Keyboard problem

Hi,

after a successful install of Monterey on my hacktinosh I'm having problems with the keyboard layout.

No matter what I do the OS is treating the keyboard as an ANSI layout keyboard, while I want the ISO layout.

For example, I run the keyboard configurator tool of MacOS, select ISO, and the keyboard still behaves as ANSI.

I also tried to delete 'com.apple.keyboardtype.plist' but without success.
