You can include SATA drivers on a Windows CD, you just have load the addition drivers on a newly created Windows CD. You can use nLite to create and customize your own Windows Install CD (with this program you can load Windows Patches/Updates/Drivers so they are accessible right away off the Windows disc).
Though if you are setting up a RAID array, which you aren't, you need a floppy drive.
Correct me if I'm wrong btw.
