I was trying to phone help a friend with an old PM G4 500mhz put a new ata drive into the second slot on the machine to get him up to Tiger speed. He's been running 9.2.2 because of old but reliable programs. So I figure he can have 9 on one drive and Tiger on another , right? He could not figure out the pins/ connectors and got a blank screen.. Also we upgraded ram to 1 gig total and certain sites in 9 OS are saying "not enough memory".. I don't know if we needed to do a firmware update or what but I thought it should be completely straightforward wtih putting in a second hard drive. It was not. Help!
