hi,
im sorry, i think HP really does not have windows xp drivers for your computer

ive encountered several machines like these (not only from HP, but from other manufacturers as well) who do not make drivers for windows xp.
i suggest you go with the default Vista instead. Of if possible, see if you can upgrade to Windows 7.
goodluck and regards
