John, yes, good ideas. I have been trying to figure out how to get into the BIOS without a functioning keyboard hooked up to press the requisite F1. We have no other type of keyboard here. I think you are exactly right, I messed up the BIOS and also the HID ports software and USB keyboard. I have finished doing everything else restoring the computer, so access to the BIOS and correcting the settings there, or just clicking 'restore defaults' - but I have not been able to figure out how to gain access to the BIOS without keyboard! I may have to do the full clean install from my older XP install disk but I'm not sure how it would work out with the second hard disk for restore in HP pavilion. If that is the only way to save the machine - or to determine once and for all if getting new equipment is necessary, then I will do it; I have put too much time and effort into applying my admittedly meager knowledge into this project that has gone on for almost two weeks, all day each day! A technically proficiant person could, I'm sure resolve this in person in an hour or less. Arrrrg! - Will
