Intel Application Accelerator RAID will not install on my P4C800-E Deluxe - anybody know why?

I did install the chipset software utility, but when I try to install
the RAID application accelerator, I get a "incompatible hardware"
warning. OS is Windows XP Pro, sp2, P4 3.0ghz, 1gb RAM.

The read.me gives me no clue as to the problem:

What's going on? Any comments appreciated.

 

Is the SATA raid controller configured as raid in the bios? If it is, it
will appear as 82801ER (R for Raid), if it is not it will appear as 82801EB
(B for basic IE non raid).

Intel decided not to allow the installation of this driver forsome brilliant
reason unless the controller was configured correctly. Carts and Horses...
