graphics efi string from rom code?

[Cool McCool]

I remember doing this a long time ago when I was running either 10.5 or 10.6.0.  Its been so long I don't remember what exactly I did, but I remember some of it.  Maybe you can fill in the details for me?

 

I booted Linux and extracted the rom bios from my graphics board, an Nvidia GTS 250, which I still have.  So I have this rom code, but no idea what to do with it,  but I do know I can use it to create an efi string to get my video fully working with Mavericks.  I also know I can create a DSDT.aml file with it, which would be even better.

 

Does anyone know what I need to do here?  I'm currently running 10.9 Mavericks using GraphicsEnabler set.

 

Also, I have the CMOS reset problem and no sound, but thats for later.

 

Any help would be appreciated.

i used OSX86 TOOLS  to extract efi string 

https://code.google.com/p/osx86tools/downloads/list
inject the hex string with chameleon wizard 
remove any enabler 
remove graphicsEnabler 
and it works fine 
except randomly OpenGL crash when using maps or photoshop   

this is my boot plist
