Hi David,

The Matrox Mystique display card needs  "VideoPortVerifyAccessRanges" 
as per Bug # 93.
Following this commit I tested again the support  of this display card
but without success. This function is still unimplemented as per Debug
messages.
I assume that the ATI board does not need this feature .
Does anybody use Matrox board ?

Now that you put this

Are the values of cr2 = 1f0180 and eax = 1f0180 a coincidence?

I once was getting the same exception this weekend

Page Fault Exception: 14(0)

And was not able to see the value of eax (wich contained an address and was showing the same value as cr2 and was not a coincidence for sure)

Waldo Alvarez
