Hi everyone. I have ordered the M4A78 Pro motherboard and an AMD Phenom II 940 processor. I see that the spec shows the motherboard is compatible with Hybrid Crossfire. However, the video card I will be installing on the motherboard (ATI Radeon 3870x2) does not support this. I am unsure how to configure the BIOS so that the onboard video is disabled and the PCI Express card is the boot device. I am hoping someone with experience can give me some guidance.

It looks like I would need to set the Internal Graphics Mode to [Disable], and I am guessing I need to set the Primary Video Controller to [PCI-GFX0-GPP-IGFX]. Is this correct? Are there additional settings changes I need to make?

Also, is there a good reference for the various PCI Express options such as the port options?

When I set up this new M/B I just installed my old 8800 GTS pluged the Monitor to my 8800 the old O/S hard drive just 1 drive to get the rig up and running 2 sticks of old 800MHZ Ram 1 gig each all from my old rig it fired right up with out doing any thing In the BIOS.

If you have more than 1 drive plug 1 in at a time and just restart the system each time as in first install you O/S (C) turn off the new rig then install lets say you(H) drive 2nd H/D then restart do this with each H/D so you will have them in the same order as you'r old system maked it a lot easyer to find what you'r looking for rather than relearning where stuff at.

I just install the very minmum just to get ther new system up and running then download all you'r drivers and up dates a  needed.

After all this is done install the rest of you'r add on cards or what ever download all there drives and up dates then if you want up date the BIOS or start you'r O/Cing.

My last M/B had a lot more On board stuff built into it I had to use more add On PCI cards to get this new board to do the same function as my last board did, but my last M/B was not built for 140 watt CPU + it died on me anyways.

I did exactly what you are saying, I disabled the Internal Graphics Mode and set the Primary video controller to PCI-GFX0-GPP-IGFX and the result I got was no video at all! I had to clear the cmos to get back into the bios. I haven't been able to figure out how to disable the on-board video and enable the pci-e slot. It should be simple straightforward process to achieve this.

Good luck

I built my rig using the onboard and once os and drivers were updated dropped in my gtx285 and everything auto set,never had to mess with any bios settings. It is supposed to auto disable onboard once you install in the pcie slot and should turn back on when it is removed. you might want clear cmos and try booting with onboard then shut down,install card and dont touch the bios and see if that works

I'll give that a try and see if it works. Hopefully that will do the trick, as I don't really want to have to rma the mb and swap it out.

You have to set GFX0 to be first for some reason, or it doesn't seem to see the PCIE card at all. They say it's supposed to be automatic, but I found the same thing as you. If it's not set with IGFX first, and you don't have a card in it, you will be stuck with no video until you can see the BIOS again and change it. It's really weird, because the way it looks, it should look for any devices in that order, right? Well, it doesn't.
