Hi Timothy,

My Intel DQ45CB cannot have secondary video card. It is a single PCI-e
x16 while you have two PCI-e x16 slots on your motherboard.

In my case, I blacklisted nvidia video driver first before rebooting
into text mode on Dom 0. nvidia video driver will not get loaded on dom
0 then. Then I hide nvidia pci-e x16 from dom 0 directly at the virtual
terminal. I didn't use ssh from another computer.

Then I start Win XP Dom U directly at the terminal also.

I saw Boch BIOS, then Booting from Harddisk....and then saw Windows XP
Home Dom U booting up.

But when I tried to shutdown Win XP Dom U from VNC, the display hangs at
"Shutting down..."

Then I need to do a hard reset of my computer.
