The connecting is to a bus that has addresses. If you plug something in while it is on, it is supposedly going to have addressing problems. It would seem that just sticking it back in after it fell out wouldn't cause a problem, but rebooting doesn't take that long. -Tim (I am by no means a hardware expert, I am just remembering what I've read) Tim Butler (tbutler@wpi.wpi.edu) Teaching Assistant HL 103b ext.5424 Department of Mechanical Engineering Worcester Polytechnic Institute
