That's easy enough. It really depends when and where. If Windows is running then the default usb 2.0 support is active. But if you are working on a drive without an OS and are then going to install Windows you will soon find a need for the standard PS2 connection in order to press the F8 key when asked if you agree to the license terms. It's always a good idea to have even a little cheapo keyboard hanging if a PS2 type has need. Wireless keyboard can even be more fun.
