Administrators Hervé Posted January 30, 2013 Administrators Share Posted January 30, 2013 Mmm, well, not all custom BIOS were successful, so careful... If you don't have an operational Win install, create a recovery USB key with a basic DOS bootable installation like Unetbootin. Then simply copy the downloadable exec from Dell on it and run it. That'll update your BIOS. If I were you I'd stick to standard/regular BIOS A08 and use regular DSDT file. Re: .hdr extraction, a little home work will suffice. I'd even expect you to find the magic trick in less than a minute... Link to comment Share on other sites More sharing options...
Bilko Posted January 30, 2013 Share Posted January 30, 2013 you say use the one from dell, that implies community mod is not working ? http://www.osxlatitude.com/wp-content/uploads/2011/07/D520-Intel-OSX_SLIC_LOGO.zip extraction from exe is cool now windows is running, just updating. its not seen the light of day since 15/8/2012 not sure if os version is correct the coa is missing but its oem so gave it cert and key, just waiting on the reboots.

Administrators Hervé Posted January 30, 2013 Administrators Share Posted January 30, 2013 Some custom BIOSes caused problems. I don't know about the D520, I don't own one; so, as explained in the thread, try it/use it at your own risk... Just be prepared. Anyway, this is not the place to discuss BIOS updates or Windows. This is a thread about Lion on D520. Link to comment Share on other sites More sharing options...

bobdamnit Posted September 26, 2013 Author Share Posted September 26, 2013 D520 is running smooth. If I use Joe's DSDT with the VGA out fix, its almost perfect. Sleep/Hibernation works. Display won't wake up after sleep/hibernation, even with a hotcorner display sleep setting. However, tapping "Enter" seems to wake the display back up. Still see "Refusing" errors after running EDP, but they don't seem to make any difference. They are all kexts I know to be running. Not a big deal. All in all, a decent running D520.
