How To Install 2 Different Graphics Drivers Concurrently

I have an Asus M4A785TD-M EVO motherboard which has integrated ATi HD 4200 graphics. In order to get better graphics performance when running Adobe LightRoom and Photoshop under Win 7 (64 bit) I added an ATi HD 5570 graphics card (manufactured by XFX). Windows reports a Code 43 error against the HD 4200 hardware, implying that no driver is installed. I want to correct this error.

It is easy to locate and download the latest catalyst drivers for both the 4200 and the 5570 hardware (they are different), but I cannot understand how both sets of drivers can be installed concurrently - surely the files names for various software components are the same, so I either end up with support for the 4200 installed or the 5570, but not both - don't I?

Or is there some work around?
 
Depending on your driver version, it should support both. The newer drivers are geared more current gen products, so moving back a few revisions might be worth a shot.

However, unless you have a ton of displays, running the 5570 alone and disabling the 4200 in BIOS would make more sense and less hassle.
 
Thanks for the advice; I had thought (based on reading somewhere, some time ago) that the 4200 and 5570 could run together in some sort of software emulation of crossfire - is this not correct?

I like the 'less hassle' aspect of your comment and you also say it would make more sense to run without 4200 - more sense in what way?
 
From what I can gather, the only way you'll run Crossfire is with a low-end 2000 or 3000 series Radeon. If you do manage to get it working, that's great, but it appears the 4200 was limited to what it could support. I don't know where the limitation lies be it software or hardware, but AMD didn't seem to have support for anything past the 3000 line. While it's possible to run on-board and discrete graphics, traditionally, the on-board is set to automatically disable--and that may be part of the problem here (assuming non-compatible Crossfire option) as far as error codes go.

Unless you need more outputs than is available on the 5570, leaving it enabled is wasting energy, both yours and your electricity--not tons, but no good reason if you can't use it. If you do need additional outputs, you might still be able to run the 4200 and have the 5570 swapped with an nVidia-based card. However, you might still run into the 4200 being automatically disabled.
So basically, banking on the 4200 working in tandem with an additional card in any capacity is limited from everything I've read.
 
Thanks, the situation you describe is as I have experienced it: I never seemed to get any addition performance by using both 4200 & 5570. I have now disable 4200 in BIOS, installed latest AMD Catalyst driver for 5xxx HD series and everything works at least as well as before with the added advantage of no error codes/warnings.

That's god enough for now.

Thanks for your help.
