A8V-Deluxe and Promise controller, missing driver?

I have an A8V-Deluxe. I set up the Promise controller for IDE mode
(set in BIOS). I installed the IDE driver (not the raid one) for the
Promise controller, it loads. However, it immediately comes up
detecting another device called the "Promise SCSI controller
processor" -- but there is no driver on the ASUS disc that appears to
apply. The actual controller driver has loaded and it works, but this
second "SCSI processor" device appears. I have downloaded the latest
driver from ASUS's website, but still nothing. It's like the driver
package is missing a driver.

Any ideas?
