Windows XP is not totally compatible with this board; the support is limited due to discontinuance of OS.
You are able to install the OS if the board is on IDE mode. If you want to use AHCI or RAID mode, you need to install some drivers during Windows installation (F6 drivers)
If the OS was already installed on IDE, you cannot just change the mode and try to run Windows. First you need to change the SATA mode to AHCI on the BIOS, then load the F6 drivers and install Windows from scratch.
You will find the drivers you need to install on the following link. You may want to read the Read Me file first.
Keep in mind that this is a process that Intel does not support, therefore if you need further advice about the slipstreaming process, check different online resources.
