hello! I need to to find out how to disable an onboard VGA adapter. I recently purchased this motherboard, a L7VMM. AMD K7 1.4ghz T1600. I've been trying to install an AGP Video Card (ASUS 9550 128mb). The onboard video card is a ProSavage3. It should, for all I know default to the AGP, but it doesn't. Essentially, the process goes is this: I uninstall my old card (the onboard) in windows. I disable it, too. Then I shutdown, plug the AGP in, reboot, and viola, it works. I install the drivers, and everythin seems peachy. BUT when I shut down the PC, that's when the trouble starts. I come back later to boot it up again, and there's no screen. It just says "no signal." It does this for the old card, too. I've tried other monitors, same situation. After I remove the the AGP card, it works fine again.
I've tried to disable it from the motherboard and the bios.
It doesn't work----- I'm to understand that this particular motherboard has NO jumper for disabling the onboard card. The bios is also missing an option like that. There is a "Shared Video Memory" option, but I can't set it to zero.
I've tried dumping the cmos memory, I've flashed new bios (there were a number of new options available after this), read the manual, configured it to exactly "how it should be" and it still doesn't work!
Let me re-explain:
With the onboard savage3 installed and running, everything is fine. I check device manager, and then right-click to disable it/uninstall it (i've tried both). It asks to restart. I do. Then, the machine re-boots into xp, finds the vga card, yada yada and asks me to help it find drivers. I say no thanks, shut the computer down. I install the AGP card. I reboot. This time, everything works. The screen comes up, XP loads, it asks for the drivers for the AGP card, etc. Everything installs fine. the card works fine.
I restart the machine. I enter BIOS, set it to initial-on AGP (not PCI), I enable PnP. I save and exit. Everything works fine, XP loads. then I shut down the machine. I turn it on again, but now NEITHER the AGP or the onboard WORK!!! the monitor comes up with "no signal." I shut it down, unplug the AGP Card, lo and behold: the original onboard vga works. I'm back at square one. It seems like the mobo lets the AGP take over, just once. I don't know... I've seen a lot of posts saying to set the BIOS Shared Video Memory to 0, but there is no option for zero, just 32, 16, 8, or 4mb.
I'm sure my cmos battery works, I've read the manual for the mobo, I know I've set the BIOS correctly.
Oh, and the onboard uses the AGP bus, not the PCI.
thanks I hope someone can make some sense of this.
