Does anyone know how to prevent the Uno from running the last program when it's powered on?

Many times I have changed hardware and wiring without clearing the program first. Then when I power it on to upload the new program it will run the old program until it's uploaded. This has many potential unwanted effects when the old program is running with the new hardware installed.

Thanks
