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

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

Not ES82, ESB2 as in Enterprise South Bridge.
It's a variant of the 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.

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?

[Gringo Vermelho]

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.

explains why you also can open your dvd tray using logitech keyboard

[Gringo Vermelho]

I guess so.

Thanks for the replies everyone. I'll look into the dsdt patching, as I wrote I saw a post recently on this but now can't find it

Cheers

The links from this post fixed it for me with no additional kexts required...

Easier to resolve this DVD fix in Mountain Lion: works well here, even i have auto sleep working. I hope it helps.

[Gringo Vermelho]

Thanks for sharing. Where did you find that?

[xmen107]

Olarila.com

[D-an-W]

@xmen107 does that fix the Eject issue too?

[xmen107]

I think it does, here is working.

[D-an-W]

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?
