For a while anyway...
What the heck was all that about?
I ran the update, in XP Pro 32 bit, then restarted to black screens. I scratched my head, then restarted (hard) to more black screens. Then I moved the mouse and saw it appear from the side that my powered down third monitor was on. It stopped when it got to the side that my previously main monitor, connected to the 8800, was on. Hmmmm...
The updater had disabled the drivers for the 8800, made the powered down monitor the main monitor, which resulted in the other monitor connected to my 2600 remain black at boot. I had to reinstall the 8800 drivers, restart, and rearrange everything.
