The MINIX 3 license is a clone of the Berkeley (BSD) license. In plain English, it says you can do whatever you like with the system provided that (1) you agree not to sue us under any conditions, and (2) you keep the credit lines in the source, documentation, and publicity unless other arrangements have been made. Specifically, you are free to modify the source code, redistribute it, incorporate it into commercial products with only the above restrictions."
Note the passage "unless other arrangements have been made". I am pretty sure Intel made such an agreement with the MINIX 3 developers for this reason.
