Here is a rar file containing all the drivers for this desktop pc:
The SATA Driver is "Intel(R) ICH9R/DO/DH SATA AHCI Controller" located in the file: iaAHCI.inf
Use nLite to Slipstream it in your Xp CD.
* Install Nlite
* Insert your XP Disk into the cd drive
* Run Nlite, it will ask you where your xp installation is. Chose the drive the XP disk is in, and it should recognise it.
* Next, it will ask you where you would like to save your installation.
* Next, Task Selection Screen should come up. Make sure you check Drivers, and Bootable ISO. I also like
