Thanks for the somewhat delayed reply
Some of this isn't quite clear to me but certainly the slip-streaming
part I've seen mentioned on line before.
It turns out that my motivation for doing all of this had to do with
what I thought was some sort of major failure in my box; it would hang
up randomly when trying to boot one of the SATA drives. It gave me all
kinds of ATA port error messages and then it would get stuck.
It turns out that when fussing with BIOS, I happened to click on a
selection in BIOS called something like "system health". In this
window, there was a section that showed the various voltages out of the
power supply; a +5 volt line only showed something like 4.20 volts.
This fact, along with the fact that I discovered that the box would boot
with any /two/ drives, but not with /three/, led me to believe that the
silly box just needed a new power supply.
So now the old box is back on line and I can be more methodical about
setting up a new box and not be in a panic
