Greetings, unless you have a problem with your Mac OS or you find that Windows 7 is sluggish, locks up or crashes frequently then you can ignore the message. Since you are running Windows in a virtual environment it's not unusual for error messages to pop up on occasion. Parallels uses a bios as part of the virtual environment and can only be updated by Parallels. All you can do is make sure you have updated to the most recent version since this is a known problem with some installations. While Parallels is convenient to have two OS's running at the same time, if it becomes too much of an issue you may want to consider Boot Camp as a option until the bug is fixed. Dan
