Update with some more info.  This may be a monitor setting or 
something.  I took the video card out and put in a different card, ATI 
actually.  It works with the EV700 but not the EV910.   No BIOS screen 
on the EV910 but works on the EV700.

Another thing I noticed, when I switch displays after logging in, the 
EV910 is not as bright as usual.  I'm not sure how that would matter but 
thought I would mention it.

Anybody ever seen this before?  If it was the OS then that would be one 
thing but not even the BIOS screen works.  I thought that would even if 
nothing else would.

Thoughts?
