EFI EZStrings v.2 (efigfx)

11 posts in this topic

Recommended Posts

EDIT: I'm no longer working on this, I was taking the wrong approach.


devZero has EFI GFX string installer here: http://forum.insanelymac.com/index.php?showtopic=112577



Injectors don't have all the dev ID's, NVCAPs may be screwy on laptops, EFI strings are the way to go.


Netkas made a great utility but I wanted to try to make it more automated. This first iteration is just a few scripts but handles making backups and all of that...


Try here.


*Remember to delete NVinject or any other injector you may have been using.

Problem with newly added 8400m, the output is listed as below:

cd ~/Desktop/efigfx && ./gfxutil -s -n -v -i hex -o xml .8400m.hst.txt efi.plist && sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit efi.plist

./gfxutil: invalid hex inputfile (filesize dont match or zero) ‘.8400m.hst.txt’!

Fixed the .dmg so that you can drag the efigfx folder to your Desktop properly (oops), also added a script to make a 8400m hex file.


sorry I don t have removed nvdanresman and nvdan50 in first post in http://scottdangel.com/blog/?p=28

now i ve retried and what happens:

I don t have black screen system profiler show 256 mb RAM and don t show pci lane x16 ,just pci , and no quartz or dvi,vga svideo tv out don t work


I have 8600m gt 512 with hdmi s-video tv out


so I retried:

I change a value 0×01000000 to 0×0200000

and now i ve got 512 mb show in system profiler but no QE/ci or output working

I think the folder for 8600M_gt is not good maybe bad nvcap ?

but what is amazing is terminal don t show the good memory 0×01000000

and maybe the bad output

if any can help

I installed efigfx v.2 in my Asus Geforce 8800 GT 512mb, everything went fine and I gained some points in xbench and cinebench in comparison to NVinject. But when I go to about this mac it says


XFX Geforce 8800 GTS Alpha Dog Edition EFI




I could have some problems or is it normal?




I created, using the guide on osx86scene an EFI string for my Asus Geforce 8800GT 512MB, If someone have my same card, the string is on the attachment.


4800 to 5100 in cinebench.. :(


I think I can do better, I saw some Geforce 8600 do 6000 points. Is there a way to boost performance?

johnniecarcinogen, are there efi gfx strings for dual monitor setup? I have a Laptop with a GeForce Go 7600 + monitor on dvi. With the gfx string supplied the internal works, now trying to get the external going without Natit, NVInject, nvkush etc ..


Can you direct me into the right direction?

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
