Multiple Drive Arrays Setup
Raid 0
Raid 0+1
1. Hook up the drives to serial port 1/2/3/4. You will experience a better overclock if you plan to do so. Put the drive on ports 3 or 4. For 0+1 1/2/3/4 will be used and overclocking will not be as likely.
2. Very first thing we will do is boot into the BIOS and go into “Standard CMOS Features”
3. Check to make sure your drive is located on what SATA channel you have the drive plugged into
4. Go into “Integrated Peripherals”
5. Press ENTER on “ Onboard Devices”
6. Press ENTER on “RAID Config”
7. Locate the “SATA1/2/3/4 RAID” make sure whatever port your hard drives are plugged into are enabled.
8. Return to “Onboard Devices” menu
9. Locate the SATA1/SATA2 – SATA3/SATA4 and enable these options.
10. From here we will exit/save
11. Upon posting you will now see the NVIDIA Raid Bios and press F10 to enter.
12. Here you will see your new drives located on the left side of the 2 panels “Free Disks” and “Array Disks”.
13. If you will be doing a Stripping or Raid 0 you should have 2/4 drives here use your right arrow key and make them both go over to Array Disks.
14. Make sure the Raid mode is Stripping for Raid 0 or if doing Raid 0+1 or Mirroring with 4 drives please make this change now.
15. For Stripping I would leave it at 64k until you better understand these options.
16. Mirroring leave it optimal or 64k.
17. Hit F7 (Finish) to create the array of your choice.
18. You will now see an “Array List”; as long as the drive is listed as healthy we are good.
19. CTRL-X to Exit. The computer should reboot.
20. We need to go directly into the bios right after the system posts.
21. Go into “ Advanced BIOS Features”
*NOTE*
When you have a serial hard drive hooked up to this motherboard and have arrived at this point you will be able to go into “Hard Disk Boot Priority”. Please go in here and you will see NVIDIA Stripe/Mirror here. Please make sure this is the top #1 option with your page up/down to select this.
22. You will want first boot device to be CD-ROM for Windows XP/2k installs.
23. You will want the second boot device to read HARD DRIVE; this corresponds to the “Hard Disk Boot Priority List”.
24. Save/Exit
25. As most of you know when you enter the Setup for Win2k/WinXP you will need to hit F6 to load additional drivers for other SCSI devices.
26. When you arrive at the “Press S” menu please make sure you load BOTH of the NVIDIA SCSI/Storage drivers.
This means you will load "NVIDIA RAID CLASS DRIVE" hit then hit S again and select "Nvidia Nforce Storrage Controller" hit
You must do this step or windows has no idea what you want it to search for in regards to possible storage space.
From here you should be able to complete the install of Windows XP/2K fine. You can go into the bios and make “hard drive” first boot if you wish now.
UPDATE
If you are going to use this motherboard with a raid array of any level with Windows 2k, It must be Windows 2k SP3+ or windows install will see only two seperate drives. You will need to create a bran new win2k cd on a differnt comptuer and upgrade the install with SP6 if you wish to use a bootable raid array!
Problem then of course is that i would be left with a mixed gig of Corsair CH5 collecting dust
