Possible methods to enable Dual Graphics on Pavillion G4/G6/G7 11xx (and others)

Probably the Dual Graphics (or CrossFireX or Hybrid CrossFire, or any other name) is the most interesting feature enabled by AMD APUs. Because of this, when you have a discrete GPU and APU compatible, it is very desirable to activate.

However, manufacturers are not always very friendly with that desire.

I've had this feature active on my HP G4-1116, but after a BIOS update, I lost, and I got the ridiculous PowerXpress.

The InsydeFlash can not change the BIOS to an older version, however I want to find a way to activate the Dual Graphics, AND teach everyone who has the same problem. But for that I need great knowledge of the community NotebookReview. Each procedure requires one or two details to work out.

General data:
With the combination of F.20 BIOS and driver version 834, the Dual Graphics worked perfectly. So this BIOS version should reactivate the Dual.

Well, here we go:

Possibility 1 - Method InsydeFlash

All BIOS updates from HP that I've seen are made by InsydeFlash. A simple program and very configurable via 'platform.ini'. However, even modifying this file to ignore versions, yet he says he does not support the bootblock downgrade.

The options I changed were:

Code:

SwitchString=RESSEN ACDIS
[Bios_Version_Check]
Flag = 0 

But no success with the flash. When the flash utility gives me the following message:


Is there any string to be changed in 'platform.ini' that completely ignore the BIOS version, or to make a mask in version?


Possibility 2 - Method InsideFlash (troll)

Another possibility that I saw that might work is the most troll of all: change the version of the BIOS F.15 or F.24 to F.56 (larger than the one currently installed, F.52), which would make the InsydeFlash able to install the bios without problems.

To do this, you must use an hex editor, repackage the bios file in the BIN flashable by InsideFlash. I believe this method, with the aid of you would be most likely to succeed.


Possibility 3 - Method BIOS (SIG override)

The G4 has a BIOS that rollback recovery consulting folders BIOS (by pressing 'Esc' during boot, F2 and then selecting "Bios Management"), which keeps a backup of the previous version. However, when I attempt to rollback this method by "official", it says signature verification failed BIOS.

However it was made by the utility from HP ().

If you can make the file ".SIG" compatible with the utility rollback also will achieve the goal of flashing the previous version.


Possibility 4 - Method Win key + B

In theory, this would be the method most recommended by my research.

However, when I press Win + B key, it flashes the caps lock for a long, long time. And not advance.

No matter where I put the files if I put the partition structure HP_Tools, or if I put the BIOS file copied as SMC.bin. The result is the same. There are some other procedure? What type of file should be placed and how it should be put?


And finally, the last procedure that could solve:

Possibility 5 - Method drop-everything

The last possibility is flashing with some universal utility that supports flash chip notebook. The problem is to know which utility work and especially flashing which file (the. Bin "compressed" that comes in the package from HP, or. Decoded bin that arises when using Phoenix Tool). No need to mention that this procedure is only used as a last resort, is not it?



As you can see, we have a range of possibilities, but I do not have the knowledge to run them.

I would ask your help to complete one or more of the procedures. And every solution, will update this post. We have to have control over our notebook!
