I mean -persistently- (only humans can be stubborn)
Before I attempt the task you've set, what do you mean by "If you have more than one RAM module installed, try starting computer with one RAM stick at a time". I don't know the answer to that. Do you mean USB sticks?? The USB connections don't function. No external drive or printer.
You are right about the auto booting into Windows XP Home Edition CD Rom - I have 10 seconds to choose that one or (2)to go to Restore and that's it. I tried Restore once but the default choices I mentioned before didn't show up. I opted to go with what worked - Home Edition.
