OK we have these computers installed in this libary. I think they are Dell 760s or something like that. They have the onboard VGA and a DVI card installed as well. The monitors are hooked to the VGA. I thought that VGA was automatically disabled when a DVI card is installed. How did they work around that??

depends on the motherboards-some motherboards will auto detect whichever one is hooked up, and use that one, others will allow you to use both simultaneously.

OK. I figured this was one that disables the VGA when DVI is installed for 2 reasons:

1. All the other similar Dell models I've seen are like this.

2. The BIOS specifically says that VGA is disabled upon installation of a card.

well, either in the BIOS someone changed the setting, or for whatever reason theyre not like that-obviously because their using the VGA. Whats the big deal, their library computers either card ought to do everything they need it to if theyre working alls good.

The setting cannot be changed in the BIOS. I checked. I understand everything is all good. I just wanted to understand why and how they were able to do this.

probably a fluke, my guess is most computer manufacturers buy motherboards in lots-and sometimes, they will use different brand motherboards (same specs) or slightly different revisions of the same board, and some may allow auto detect what cards being used while others cant.
