I haven't done this for XP in a while now and I can't figure out what's wrong. I have SLP 1.0 BIOS mod for HP. I've installed XP pro from the original HP sysem CD and entered OEM key during installation when the installer asked for it. After all was done I have tried to activate via Internet, but it didn't work. It asked for a new key. What am I doing wrong? Can anyone help?
