When the BIOS is set to RAID mode, the RAID driver must be installed before you install the OS.
Copy the RAID driver from the Tools and Drivers DVD to a USB floppy drive.
Connect the USB floppy drive to a USB port on the workstation.
The USB floppy drive must be connected directly to a USB port on the workstation. Do not connect to a USB hub.

Use the Boot menu in the BIOS Setup Utility to verify that the USB floppy drive is seen by the workstation.
Press the Esc key to exit the BIOS Setup Utility and reboot the workstation using the Windows XP installation media.

Press S to specify an additional device.
A list appears.
