One thing I notice:
Shep shows this:
Code:
Section "Device"
Identifier "Volari Z7"
Driver "sis"
EndSection
The OP shows this:
as does not work,
Code:
"Device" section
Identify "voodoo3"
Driver "3dfx"
EndSection
I don't think that would work, maybe:
Code:
Section "Device"
Identifier "voodoo3"
Driver"sis"
EndSection
I suppose if you try the Driver "3dfx" it might work as well, but is suggesting that the "sis" should be used,
