I think that is normal for the card on os x there's a few people that have that experience but we can't get that far due to the difference in how the amd gpu is incorporated into our machine, I believe yours may be slightly different.SanderV3 said:i have a output if i connect a second screen with hdmi. Laptop screen is black...
So is there any way to make my ATI 6490M work? why don't create a package like Hp proboook installer for most of user like me? I read, and i can't understand anything.
) Arrange your files by size and select the files sized between 50 - 80kb (roughly 15 files) and right click> open with> Hex edit and eliminate the ones without amd or ati somewhere in the 1st 10 or so lines, I'm guessing you will be left with 4 like I was.

I downloaded the bios updater from hp support and let the program run until it asked if I wanted to update the bios via the exe program or create a usb disk, at this point it has unpacked all the data from the bios update into a folder c:/SWSetup/SP54862 including the rom.bin.
I downloaded and run phoenixtool (bios extractor) and selected the rom.bin file to be extracted. Phoenixtool created a bios dump folder from this rom.bin file which contains 1003 bios .rom files and I used hex edit to look at the files and found 4 which contained the words ATI.
I placed each of these files in turn in extra and renamed them 1002_6760_167d103c.rom and by process of elimination I found 1 which allowed my machine to boot.
Narrowing the list:
As I stated earlier there are 1003 files in the dump folder and would take several hours to eliminate the other 999 files by viewing them individually (though I did start doing that!
Place these rom files in extra and rename them as I have one at a time and boot with:
Code:GraphicsEnabler=Yes UseAtiROM=Yes AtiConfig=Ipomoea -v
The incorrect rom files will get 3/4 of the way through booting, mine happened to be the 2nd largest file, yours may be different depending on your card being 1gb ram and/or different bios version.
Mine is 512ram bios f20 and i'll attach the rom to the post shortly.
I'm hoping maybe someone can take the torch and maybe piece this and other previous posts like adding lines to the dsdt (page 3 I think) and make this thing work?
Why did I choose Ipomoea??? Well simple, there's only 2 framebuffers which made my card show up with vga in system profile and that's 1 of them!
Can you please provide more details?Micky1979 said:

Hello Dewitts, after many trials, the only real sign of life of the discrete videocard was possible with a bios Unlocked. Only once I managed to disable the HD3000, but OSX has booted with black screen , but with backlight!
Then you reset the CMOS by itself
Sign that ATI was there ready, but the display is not attached.
I spent last week in mod my bios with Phoenixtool202.exe but InsydeH20 bios is encrypted (RSA signed). These bios are difficult to hack,
But now I'm sure: unlocked bios = Discrete video card work!
In my hacked bios with Unlocked menus there are many configurations for video card:
Disable/Enable internal graphics/Discrete
Disable/Enable Futures Swiching video card (but with the ability to activate one or the other with battery or AC adapter etc.
Other things are secondary, also the video rom
Attached your rom decoded (with Radeon_bis_decode) without usefully data, while the iMac produces the output connectors of the Framebuffer.
You can find the connectors of the frame buffer (Hydrilla Duckweed, Gibba etc.) on another Modules of bios.....our Rom, seems to be not useful
