I've got an U.K. keyboard in a Dell - Inspiron 1501 and I want to configure it to Portuguese - ABNT, but when I do it, the keyboard works like ABNT2 (another Brazilian keyboard). And when I select ABNT2, it works like ABNT2.

So, how could I configure my keyboard to ABNT?
Is there any place where I can re-install the drivers or is it a known issue?

Anyone could help me???

Thank you!
Guilherme
