inspiron 1545, delete original vista, install xp, but I can only install GT10N_A109, ( flashtool).  when I try to install  other 11 drivers in CD DVD group, it always says "no compatible device is detected". when I try to update the DVD driver using CT10N_A104, it can't find any driver.  most other drivers are installed right now, except matrix storage manager.  I wonder what the problem is. thanks I hope someone can help me.
