• Install the Windows® XP Service Pack 2 or later versions before using Serial ATA.

•The motherboard does not provide a floppy disk drive connector. You could use a USB floppy disk drive when installing Windows® XP operating system on a hard disk drive that includes a RAID/AHCI set.

•Due to Windows® XP limitation, Windows® XP may not recognize the USB floppy disk drive.

•For more details on RAID/AHCI, refer to the RA ID/AHCI Supplementary Guide included in the folder named Manual in the support DVD.
