Good day! I'm running the Intel DG43NB motherboard in a home file server. I'm looking to install a non-video expansion card into the PCI-e 16x expansion slot. I'm looking at either the Intel SASUC8I or the Supermicro AOC-USAS2-L8E.
I have read the motherboard documentation, and it sounds like either should be supported. However I am concerned about one of the sections of the manual, and it reads as follows:
Table 4. DVI Port Status Conditions
PCI Express x16 connector status
No add-in card installed
Non-video PCI Express x1 add-in card
PCI Express x4, x8, or 16 add-in card
ADD2 or MEC card installed
Now, my server is a headless server (power + network), but on occasion I need to access the physical video port. Is the above table saying that ... if I install a non-video expandor card into the PCI-e 16x slot which is greater than PCI-e 1x, I will lose the onboard video capabilities?
Also, as a side question, if anyone knows whether or not this PCI-e 16x 2.0 slot supports interrupt 19, that'd be great! (apparently interrupt 19 support is required in order for the SAS controller's BIOS to function)
FYI: I purchased the Intel SASUC8I, without proof of concept, and it worked!
* Was able to install this card into the motherboard, and the board's on board video still functioned.
* The Intel SASUC8I is fully functional in the PCIe 16x slot
* (haven't tried booting from it, but the SAS controller BIOS is functional, and all devices appear in the BIOS as allowed boot devices, so presumably this would work too)
