Do you have a external usb hard drive installed on your system?

Many times if i forget to turn off the external usb drive I get that exact message.
Basically the bios can't handle the confusion.

What is truly odd is that my new Asus SK8V (a awesome board) has USB 1&2 detection in bios yet the same thing happens if I don't turn off prior prior to shutdown or on booting.
