I've installed XP onto the "D" drive of a dv9230 as an alternative to Vista Ultimate to address compatibility problems with Blackberry and Office 2K. It's set up dual boot and all devices are installed except the Conextant/ MS UUA setup which will not run (code 39) using the ms driver or HD Audio driver. Have tried various old xp and 2K versions with no success, any help or ideas are greatly appreciated.
