01:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce 310M] (rev a2)I did not find anything disabled in the BIOS. As far as I remember, I only switched boot devices (well using Esc key let you choose the booting device).
Well I am currently restoring the four AI Recovery backup DVD and I will see if it helps...
The card is still missing after recovery.
I just filed a case on Asus support web site... Follow up in comments.
