Please help me with this 10.9.5 system. Motherboard: Gigabyte 965p-s3 rev3.3, gpu: Ati Radeon HD6450 (dvi/hdmi/vga). 

Using any of the 3 ports on the 6450 (dvi, hdmi, vga), I see all the white letters on black background during boot but when they complete and it's time for the graphics to start I get a black screen and sometimes a restart after that. Using Clover 4411. Is there any way to get past this?

Framebuffer: When Clover starts and I choose Options->GraphicsInjector, I see this line:

"FBConfig:Bulrushes_"

but I don't know if that is applied or just a suggestion.

PCI ID's of card: From within windows 7 I can obtain this information: 

Vendor 1002, Device 6779, Subsys E164, Supplier 174B, Revision 00

but I am not sure if this is the information you requested.

Thank you for being willing to help.

Yes I am familiar with Clover Configurator but how can I use it when the machine doesn't even go into graphics? All I get is the (-v Verbose) messages, white letters on black background and then, a black screen.

There appear to be so many permutations!

Which port should I connect a monitor to? Dvi, hdmi or vga? Personally I'd rather use vga.

I get this message when it hangs: "still waiting for root device" and a "stop" sign in the middle.

My Boot Args: -v dart=0 npci=0x3000

And then the Options->GraphicsInjector options, as shown:

Inject EDID (Fake Vendor, Fake Product, Backlight:0xFFF, Intel Max Backlight:0000)

Card Device ID=6779

Model: AMD Radeon HD 6450/7450/8450/R5

Inject ATI (select or not)

DualLink:1

DeInit: (select or not)

   Fake ID:0x00000000

   FBConfig:Pithecia

   Ports:06

   Connectors:00000004

   RefCLK:000000

Load Video Bios (select or not)
