I have been struggling trying to install windows 7 on a computer with an ASUS Crosshair 1 motherboard. It has 3 WDD 500gb drives which is in RAID 5. Everytime I boot to install Windows 7 using a Windows 7 Home Premium disk, it doesn't recognize the SATA drives and asks for a driver. I have tried the Vista 64bit drivers as well as the "Others" RAID 64bit drivers from the support.asus.com website. I have googled a couple have options which none have worked for me. I used to have a floppy disk for this machine for the drivers (I built the machine for a friend of a family which I have now inherited) however the floppy disk has since been lost.
