Which motherboard has an explicit disable option?Either in the BIOS (press del usually at startup) and there may be an option to disable the onboard video
the HP machine I have also autodisables onboard video when an addin video card is installedI think my onboard video was automatically disabled, and used my gfx card when I installed it.
Yeah and I was asking you which mobos have that (ok now i'll ask you "which BIOSes have that?")I was pointing more to the fact that there are options within the BIOS where on-board graphics can be turned off in favour of a installed card
I have that option in my BIOS .... and I certainly dont have onboard.... (i need that option when i pop in a PCI vid card)OK, the option probably reads something more like "Make PCI / AGP card primary Boot display adapter" or the like.
Usually isI think my onboard video was automatically disabled, and used my gfx card when I installed it.
