OK, time for a review.
You have an "A7N8X Deluxe" ? It has a SIL3112 chip on it, while the
vanilla A7N8X doesn't have the chip soldered on.
There is a jumper ("Bigdawg" mentioned the jumper). The jumper is for
enable/disable of the SIL3112. We know that works, because you've
been able to do things to the disk(s).
The controller is not on the Southbridge. That means, during install
of Windows, you pressed F6 and installed some kind of SiliconImage
disk driver.
That BIOS is unique, in that the add-in Silicon Image RAID
module in the BIOS, has no configuration done in the main
BIOS screen. So there is no option to select there, such as
RAID or non-RAID.
If you enter the BIOS, and press <control-S>, that is supposed
to bring up the RAID setup screen. I haven't heard you mention
the word RAID, so there would normally be no reason to go in
there. I want you to go in there anyway, to prove that the
SiliconImage module in the BIOS is being loaded during POST startup.
If the module loads, then it is more likely to also be offering
INT 0x13 service, for reading the disks during a boot attempt.
(In some BIOSes, you have to enable something, to get add-in
modules to load, but there is no option I can see in the
Asus manual for that. Which means it is always going to try to
load, at least until it sees that the minimum number of SATA
disks is not installed.)
In the RAID setup screen, you should see your two disks, with
a notation that they aren't RAID or anything. Or maybe they
are RAID ? What configuration were you using, when this
stuff worked ?
Now when I check the manual, and check the last page here, I see
that non-RAID mode is not supported. What driver are you using
in Windows that allows you to see the disk(s). Were they once
a RAID1 mirror array, and now you see two disks ?

"6 Using Hard Drives as Non-RAID
Drives connected to the Silicon Image RAID connectors do not
support non-RAID function."
Perhaps you could explain a bit more, how you are planning on
setting these up, with your WinXP install.
