AMI MegaRAID 100 with Win XP?

I have an Iwill KK266-R and want to install Windows XP. The drivers for the AMI MegaRAID 100 chip from iwill's website says that they included whistler drivers (yes they noted it as whistler) starting back in february. Even though it says that in the readme.txt, the winXP dir isn't included. The Windows 2000 drivers don't work either. With setup, you have to hit F6 to install the RAID drivers or else it can't install. Does anyone know what I can do, or where I can get the XP drivers? Thanks for the responses
