Just bought a used OptiPlex GX260 and don't have the driver CD. Got a couple of questions: 1. It has a 40gb hard drive. What's the maximun it will run? 2. Got all the drivers from the dell website except for the USB Controller, I believe it may be the IntelĀ® ICH4 USB 2.0 controller and it just can not be found. Anyone got it or know where to find it?? Thanks Bayman
