Don't anyone fret too much over this. The workstation is now just an old HP that I happened to have on hand when my original workstation died. I was no longer in a mood to replace its motherboard, so I decided to donate it.
I've been meaning to upgrade that for a while now, and this seems like a great time to do that. I just ordered a DELL Optiplex 9020 that will be here Friday, so although I'm still curious about this issue, it probbaly won't be an issue beyond Friday.
And I can tell it's tomato-basil soup just by looking at the jars.
