That screwed-up computer has been "unscrewed"....

I hope you'll all forgive me for patting myself on the back here, but it's not every day that a computer disabled by a bad BIOS upgrade is brought back from the junkyard gate and restored to health and active use. And now that I've undone that idiotic mistake I made at the beginning of this week, it's almost been worth the several days of worrying and looking for answers. If I'm ever stupid enough to try that again without doing more 'homework' I hope someone reminds me of this week.  There's no fool like an old fool because you just can't beat experience! I'm living proof.
