Assuming were talking WinXP or Win2K, you're going to have to put the M/Bs SATA drivers on a floppy disk and load them when the OP/SYS installation gives you the F6 key option, in the very beginning of the setup process, you are allowed a certain time period to press the F6 key, or the installation will bypass the option, for loading any RAID or other necessary drivers.
It will ask you later in the installation for the drivers not when you press the F6 key.
The SATA drivers will be found on your M/Bs installation CD, it probably will be listed under RAID or SATA in the Drivers section, explore the CD and copy those files to the Floppy, and insert the Floppy with the drivers when the Windows Installation asks you for them.
Hopefully you do have a Floppy drive some computers do not, but the F6 feature only accepts the input through the A:\> drive, you can get a USB Floppy drive and load the drivers through that if you don't have a Floppy Drive in the machine.
When I create the Floppy Disk as a general rule I always enable the 'Show All Files' feature in Folder Options, just in case the RAID or SATA drivers have Hidden Files in them.
Then with the SATA drivers loaded in the installation setup, Windows will be able to see the SATA HDD and you can install the OP/SYS.
You didn't get much help here so if you have any problems feel free to PM me I'll be glad to help you.
