Ultimately I disconnected the other HD, and attempted several times to do the repair install from CD-ROM. Repeatedly it would progress to a certain point, reboot, but only to a black screen with a mouse pointer. Tried again, with original XP SP2 CD, thinking maybe it was an XP3 driver problem. Same results.
Every time I've tried, I get the "Setup has already attempted to upgrade the following Windows installation" message and tried to continue from there. I'm wondering if there are setup files that don't get deleted and continue to load a bad driver?
Is it possible to TOTALLY delete any/all setup files from the previous attempts so that a "fresh" CD-ROM repair install will see ONLY the system as though a repair install had never yet been attempted? What is the process? What are the filenames? (Countless hours of net research has been fruitless so far.)
Thanks so much for your insights!
