first you need to download the drivers from the following page that are correct for your version of windows:http://www.adaptec.com/en-us/support/raid/sata/aar-21610sa/
you will need to extract the drivers to a floppy disk.
Then when your booting up the windows install disk at the bottom of the screen at some point you will see "to install 3rd party drivers press F6" when you see that press F6 and insert the floppy disk with the drivers on it.
Windows should find the drivers on the disk and you will have to confirm which drivers you want to load.
after that windows should detect the drives
