I also used the same Nvidia chipset driver and graphics driver (NForce 630a+Gefore GO 6150 graphics) and it works for our Compaq 3619AU. This may help as well. http://www.howtogeek.com/forum/topic/installing-windows-xp-w-pre-existing-vista-on-hp-laptop/page/2 Sound card was the worst for 3619AU (Connexant HD Audio). I tried all kind of things to no avail. Finally got an Toshiba driver and manually edited the INF file to get it working. Still it has some bugs and occasionally noise comes out. Some people have lucks with the HP Vista driver, not for us. For most of the other things, HP/Compaq's Vista driver/software works (wireless, card reader, bluetooth, DVD writer, etc). I believe my wife would not use Vista any more. Still I just (today) enabled XP/Vista dual boot option following the instructions here. http://forums.techguy.org/windows-vista/558994-how-install-xp-after-vista.html Regards, Xiaofan -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
