I need to disable o/b graphics to use a new PCI-E graphics card (ATI HD 5450). PC has Ameythyst 7184 m/b but in the Bios the video window is set at 64 but is grey, ie cannot be changed. I suspect the disable option is there but I can't get to it. The 'primary graphics adaptor' can be set at On Board/PCI/PCI-E but whichever is selected the graphics window size remains grey and there is no output to monitor from either device whenever the PCI-E card is physically installed. Provided the PCI-E card is not installed there is output to the monitor (from the o/b socket) whichever primary graphics adaptor option is selected. Any help to disble o/b graphics would be greatly appreciated.
If this is the board, link it looks as it should disable the onboard graphics automatically. The way I installed my Gforce card was to install the drivers for it first, using onboard graphics, then I shut down and installed the new card. Connected the monitor to it and was running ok on bootup.
Thanks but I can't get to windows as there is no monitor output once the PCI-E card is fitted. Do you mean disable via DM when the PC is running normally and then shutdown and fit the PCI-E card. Is there a risk that the PC then won't restart at all?
Well spotted *rdave13 * I missed that bit of the spec. Still it does not seem to be working. I am not sure your way of installing drivers will necessarily work as ATI will actually flash up an error message is no compatible hardware is found. Worth a try though.
The PC won't POST with the PCI-E card fitted so I can't see how installing under Windows will resolve this. Similarly I can't see how disabling ob graphics in Windows device manager will help as the problem on restart is before Windows loads.
I can't easily try these ideas as the PC (but not the new card) is now ~ 100 miles away with my daughter. I wondered about 'use factory settings' in the BIOS. I can get my daughter to try things over the phone, but not 'on demand'!
This all relates to a new game (Sims3) my grandaughter has had for Christmas which I don't think will work with ob graphics.
I suspect that you all seem to be getting in a fix about things
All you have to do is install the card.
Plug the monitor to card
Install the driver/utilities disk that came with card.
Its all plug and pray.
There is no need to 'disable anything' if no monitor is plugged to the onboard it wont show anything.
Or am I that far behind the times- after all I rebuilt this machine only 3 months ago with a Foxconn bundle from Novatech.
