Trying to install ICH10R RAID controller drivers

[Vallejo]

Good afternoon, hardware gurus. I have a problem that hopefully has a simple answer.

The background:
I'm running Windows XP SP 2.
I have an Asus P6T Deluxe mobo, which uses an ICH10R drive controller, upon which I have two hard drives in RAID 0.
Windows XP is NOT installed on the RAID array - it is installed on a separate standalone drive.
The drivers for the ICH10R controller are not installed because the controller wasn't even in RAID mode when I installed Windows.

The problem:
I want to enable my RAID array so Windows can see it, but Windows crashes if I even try to boot up with it enabled in the BIOS.
I downloaded Intel's installer for ICH10R drivers, which can be used to make a boot floppy for use when installing XP. I could slipstream those drivers and reinstall Windows, but I'd rather avoid that.
I can't get the drivers to install in my running version of XP. The setup comes back with "Invalid operating system", and if I try to manually install via the INF file it does nothing - literally no response.

The question:
Does anyone know how to load the ICH10R drivers into Windows XP without the reinstalling Windows?

Thanks in advance for your assitance.

Have you thought about slipstreaming the RAID driver you need to a bootable CD (nLite can help), and then doing a repair install of XP?
