Hi,
Ok if your bios has the sata and raid controler enabled, then when you boot your system there will be an info screen that says "To enter RAID controler press F10" or it will tell you to press some key to enter the RAID controller, not sure just how your mobo does it.
It happens quick so be ready to press the key, when you are in RAID controler it will list your drives and show you just what type of raid they are setup in. To make it RAID 0 just add both drives from the list to where it ask you to add them. There should be a menu box at the top of the screen that has what type of setup you are doing, stripe, mirror ect. Select the one you want before you add any of your drives and make sure every thing is set they way you want before you ok the setup and exit the controller.
Once this is done, just boot from your Windows CD and follow the instructions of Windows setup. You will be ask by windows setup at the start if you want to install any sata, raid drivers and to press F6 do do so, press F6 and when Windows setup has finised installing the main setup drivers it will go to a screen asking you to insert your floppy disk that has your drivers on it for your sata raid. Press "S" to do this and insert your floppy, if you have two drivers that need to be installed, you just press "S" again and install the second driver.
Now that your sata raid drivers are installed, Windows setup will take you to the next step and show you what drives you have and ask you which one you want to install windows on, if there is a previous version of windows installed it will ask if you want to repair or install a fresh copy, this is where you may have some trouble.
I would just make sure your hard drive is the correct size for your raid 0 and then delete the partition and create a new one on that drive. Then you just have to tell Windows setup to install on that drive and it will format and run setup as normal.
If you decide to remove the partition and create a new one, just make sure you partition it with all of the disk space that windows setup shows.
Any way that is about it so I hope you understand what I typed and it helps you.
Later
