if your prob is trying to install XP, and the XP install disk dont find your HDD. i found no bios settings to do this. i had to integrate the SATA drivers using "nLite" into my XP install disk before i could install XP, floppy did not work, link found on, General XP Downgrade Guide for HP Laptops. SATA drivers: hp sp37005.
