First of all, this Notebook is installed with SATA Hard Drive and the drivers for the SATA Hard Drive will not be available with retail versions of Windows XP by default.
I recommend you to try using different OEM versions of XP to install in your Notebook which should work.
Since the Notebook is preinstalled with Windows Vista, the XP Drivers for this Notebook are not directly available from HP.
I had searched some for you which should work.
Download the Drivers one after the other and save them with the name along with the Softpaq Number like the example given below :
Microsoft UAA_33566.exe
So that it will be easier for you to save them and identify.
Save the drivers in one location in the Notebook and double click them once the download is completed.
Make sure that you install the Microsoft UAA Drivers before installing the Audio or Modem Drivers.
Make sure that you install them in the same order I had provided them below :
