Qubes OS Release 3.0 loads clean but then can not find the Ethernet interface on motherboard.
Qubes 3.0 sees and properly runs an Intel PRO 1000 (PCI-X) Ethernet interface.
Running on a SATA drive. Speed is usable.
Quadro NVS 295 supports dual (1920x1200 16:10) screens nicely, though had to flip them left-to-right to get the mouse to move correctly between them.
Sometimes after the disk password and before the user password, the screen(s) have a checkerboard pattern but the screens clear after a few seconds.
Everything else seems to be running correctly including sound.
Very nice!
