Sorry it took so long to get back to you....I do have a life other than this LOL

The computer that you used to download the SATA driver file to...In most cases what you need to do is this
1) download the file to desktop.
2) open file and follow directions to install to CD or Floppy media
3) Boot to XP installation CD and when it prompts to press F6 for third party driver press the F6.
4) when asked...remove the XP cD and install the Driver CD and press enter.
5) after file is loaded replace Cd with the XP CD and it will continue to install the operating system from there.

Note.
The driver file must be opened on the CD and not just copied to the CD. In some cases the computer manufacturer uses a program called "makedisk" to create the proper media to be used to install the driver file.
