video card "white list" exist for Precision T3620?
I recently purchased a T3620, and I tried to replace the original one (NVidia Quadro K2200) with low end one - NVidia nvs 295. I found I cannot get video output after power on. I put the K2200 back and it works again. I tried other old cards and none work. The cards are confirmed to be working themselves on other machines.
So the question is: It now seems that T3620 can only use the cards in the configuration list. But why T3620 cannot use other cards fitting the same spec -- PCIE 2.0 x16, no extra power supply? If I recall the old Dell workstations, they can use all kind of video cards, as long as interface is compatible. Is there white list in the BIOS to prevent other type of video card to start?
