|Found on a Dell site - after a lot of rabbit trails:|
"Somehow, I doubt you're going to be able to configure a 4600 to boot from a USB key. USB keys were just starting to become popular when those machines were designed."
This was way down on a post about flashing the BIOS.
I have looked at the posts and decided to attempt adding a 'stray' DVD-R/RW to this machine, because I know my DVD is good = it loaded on another machine, and all that needed to be done was click the icon that said 'install'. Really can't get much more simple than that.
Thanks to all of you for attempting to help. I'm just tired of trying to beat this horse into submission. [Honey catches more flies than vinegar, anyway!]
You all have a very Merry Christmas and a Happy and Blessed New Year! Ya hear?
