Ene_ATA drivers hp pavilion xz168 laptop zt1000 series laptop. model number F5548h (1p) Shoot me an email if this helps. These drivers come preinstalled on laptop image but hp does not post them. Don't know why but it is monstrously irritating. I am publishing all drivers that came with the laptop except the print drivers. I am categorizing all of them as xz168 . Some drivers are multiple OS.
