Hi,

        Thanks again.
But the screen still is black.

For more details, when I start the HVM WinXP, I can see the windows flag 
logo.
After this flag (entering the windows), the external monitor goes to 
black (no signal),
and the notebook screen goes to disordered.

Best Regards,
Tang-Hsun Tu
