mellow Posted March 27, 2015 Share Posted March 27, 2015 I cannot boot into the USB installer even. I have no error, even with a -v or -x -v boot: - I have the OS X Lion USB created with myHack - I have the D620/GMA950 custom /Extra installed with myHack - I have the BIOS settings as per recommended in Herves post. After the verbose boot loads all the Kexts then the screen blanks and there is no more internal or USB HDD activity. I tried a boot flag of GraphicsEnabler=No but nothing extra there. Any ideas?

Administrators Hervé Posted March 27, 2015 Administrators Share Posted March 27, 2015 Depending on your LCD resolution (WXGA or WXGA+), you have to use a different DSDT file. Make sure you use the correct one: the LoRes or the HiRes. Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted March 27, 2015 Administrators Share Posted March 27, 2015 you also need to know what graphics your system has. check in bios info. Link to comment Share on other sites More sharing options...
mellow Posted April 9, 2015 Author Share Posted April 9, 2015 thanks Herve and Bronxteck I have used the LoRes files as my screen res (under windows) is maxed at 1280 x 800. I have the GMA950 graphics, and I used that boot pack, low res version. Any other boot options I can try to move this onto the installation screen? thanks Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 9, 2015 Administrators Share Posted April 9, 2015 A problem with the Lion installation app/package maybe? Legit copy or torrent download? Link to comment Share on other sites More sharing options...
mellow Posted April 13, 2015 Author Share Posted April 13, 2015 It was a torrent source actually.. but it appeared to be the Retail installer. Link to comment Share on other sites More sharing options...
