Need help with new setup and SATA RAID array

[ScissorClaw]

I set up an IS7 last night with two unformatted SATA Raptor 36GB. Want to set them up in RAID, but can't seem to get windows to recognize the disks. I did put the RAID floppy in at the F6 prompt, but still Windows XP could not find the drives. Anybody know any special settings I should set in the BIOS to help it along? Is their a RAID setup I need to do first
UPDATE: I got Windows to see both drives but they are seen as seperate drives, not a 72 GB drive. What have I done wrong? And how do I fix it?

If you are planning to overclock your system, go into "SoftMenu Setup" and make sure to set your AGP/PCI Frequency to 66/33 Fixed. The ICH5R is sensitive to timings and may not recognize your RAID array if the frequency is increased.

Make sure you increase your DRAM voltage in "Soft Menu Setup" to at least 2.65v. 2.7v or 2.8v are recommended if you are overclocking.

1. Go into BIOS, select "Integrated Peripherals", "Onchip IDE Devices." At the bottom of the screen you'll see "Onchip Serial ATA Setting" with several choices beneath it. In "Onchip Serial ATA", select "Enhanced Mode" and them move up to "Onchip Serial ATA Mode" and change it to RAID.

2. You may need to go back to the top of "Integrated Peripherals" screen, and set IDE Bus Master to "enabled." This setting may need to be enabled depending on your particular hardware setup. This one is optional.

3. In "Advanced BIOS Features" set Hard Disk Boot Priority to "Bootable add in device". Select "Onchip SATA" to boot from the array on the ICH5R. Set the boot device order to Floppy, CDROM, Hard Disk.

F10 to save and exit the BIOS and reboot

During the POST, you will see the Intel RAID BIOS load. Hit Ctrl+I to create your RAID array. Select your stripe size. 16K, 32K and 64K seem to be the higher performance settings depending on what your main applications are, i.e. gaming vs. video editing.

When you install WinXP, select the "Full Format" to format your RAID array. Do not use the quick format. Users have reported problems with the quick format. Full will zip by quickly.

Press F6 to load drivers when prompted (pay attention, it may go by quick).
