If you have a SATA drive, you can tell by opening the case and lokking at the cable connected to the hard drive. If it is a thin wire cable, it mabie red. It is a SATA, if it is a longer or wider thin cable, it should have a red line next to the power connector. Then you have an IDE cable, and may have other problems.
Here is a walk through on how to use your SATA drive when installing XP.
Copy the drivers from motherboard support CD *\DriverDisk\SATA\*.* into root directory of floppy disk. (i.e. root directory of floppy disk should contain \pide and \sata folders, txtsetup.oem, etc. files.)
Then, boot system by Windows XP installation CD, when the message "Press F6 if you need to install a third party SCSI or RAID driver" shows up, press "F6". Then, press "S" to specify additional device when next screen pops up. Put the driver floppy disk you made in and press enter to continue. If the floppy disk is made successfully, the installation program will ask for selecting driver. Please then select "VIA Serial ATA RAID Controller(Windows XP)".) After SATA driver loaded and Windows XP can recognize the SATA HDD, you can continue to install Windows XP as usual.
If this will not work let me know and I will suggest other things.
