121fred Posted July 21, 2012 Share Posted July 21, 2012 Hi all GM install worked all OK except that the dvd drive does not work as in inserted disk doesn't appear on desktop even though the drive goes through all the right motions, spins, lights flash etc. DVD player gives "Valid DVD Drive could not be found -70012" message. Drive works under snow and lion just not ML. Did recall reading something recently about DSDT mod to identify drive correctly but can't find it again. Anyone help? Cheers Doh! Feels like idiot - remember to check show cd and dvd in finder preferences, fixes non appearance on desktop This fixes dvd player error http://reviews.cnet.com/8301-13727_7-20070591-263.html Link to comment Share on other sites More sharing options...
eep357 Posted July 22, 2012 Share Posted July 22, 2012 editing DSDT to have SATA controller show as ES82 will also fix the DVD internal driver error, as well as fix hard drives ejecting when sleep/wake Link to comment Share on other sites More sharing options...
Gringo Vermelho Posted July 22, 2012 Share Posted July 22, 2012 Not ES82, ESB2 as in Enterprise South Bridge. It's a variant of the ICH6: http://en.wikipedia....roller_Hub#ICH6 From a quick google, it looks like it was first used in the MacPro1,1. Warning, people have reported data corruption/loss issues in the past when using ESB2. 1 Link to comment Share on other sites More sharing options...
eep357 Posted July 22, 2012 Share Posted July 22, 2012 Data loss on MacPro or hack? Haven't had any issues that I know of and having keyboard DVD eject (on non apple keyboard) no orange drive icons, no ejecting hard drives during sleep are all nice things, I like my data a whole lot too, even more than those other things. Couldn't find anything online either other than references to the warning message when installing the windows driver. Enabled via DSDT but was under impression legacyappleahaciport.kext does the same thing? Link to comment Share on other sites More sharing options...
Gringo Vermelho Posted July 22, 2012 Share Posted July 22, 2012 On hacks. Try to find older posts from when people started patching in ESB2 via DSDT, not sure what timeframe, 2009-10? I had some kind of trouble with ESB2 myself and quickly switched back to using an injector, but it's been too long and I don't remember any details. I know I wasn't the only one. I posted under a different name back then. I recommend using the Chameleon AHCI/ATA injectors. For some reason they're not in the Chameleon source tree anymore, but they're still easy to find. You lose hotplugging in AHCI mode with AHCIPortInjector.kext, but you get properly recognized "internal" drives on any ICH controller, so no weird device self-ejecting issues or orange icons.

D-an-W Posted July 29, 2012 Share Posted July 29, 2012 From what I can translate that method seems to concentrate on making the DVD player work with an external drive and not making the drive itself appear as internal? Link to comment Share on other sites More sharing options...
