Is this a dead controller, a dead disk, or both? ... Error 162 indicates that the hardware configuration does not agree with the stored setup. It can indicate a component failure, external device not turned on, etc., but in most of the machines I repair it results from a dead lithium battery (which backs-up the RAM which holds the setup parameters, and runs the internal clock/calendar). The battery lasts 3-5 years. Measure the battery voltage; if it's less than about 5.5 volts, replace it. Then boot the reference disk and reconfigure. -- Frank Reid reid@ucs.indiana.edu
