The question is in title, is possible to have Full HD resolution at boot ? (Where you choose your OS and display the Apple logo)


PS : i use chimera 1.5.4 and it seem to ignore graphics mode string :<

Not sure what you mean with Full HD but in SL 10.6.8 and Lion my Sapphire 5750 works with just pasting the (xxxxxx68be) in the plist of the ATI5000controller.kext. And in the com.boot.apple.plist I have graphicsenabler=no.


Locate this and paste it last in the stringline




<string>0x68981002 0x68991002 0x68E01002 0x68E11002 0x68D81002 0x68C01002 0x68C11002 0x68D91002 0x68B81002 0x68B01002 0x68B11002 0x68A01002 0x68A11002 </string>


Whit this I get full functionality except for all three ports working the same time. They all do work individually and two at a time though so you at least get two monitors QE and all.


So if somebody knows how to get the displayport to work properly so you can use all three ports that would be great.
