Thanks for that useful contribution. You should attach that kext for the benefits of others.

The NVRAM module is a Chameleon boot loader module. You place it in /Extra/modules along with any other Chameleon modules. That's where they go to be loaded by the boot loader.

Why on earth would you mix that bootloader with myHack when myHack installs the full legit Chameleon? Stick to myHack/Chameleon. If you've done basic research, by now you know that Optimus is unsupported on Hackintoshes and you need to disable your nVidia GPU to fallback on the integrated Intel HD (usually, people cannot disable the integrated Intel HD GPU to stick to the discrete GPU). If you can't do it in BIOS, you'd have to get this done through a DSDT patch.

Yes, you need to run myFix (quick) every time you modify kexts in /E/E or replace the actual /Extra, as is the case if you use the pack I provided. Until you do that, your changes are just ineffective.

I've corrected your GPU info to HD 4600. For Ethernet and wireless, please specify brand and model as current info is of no use right now.

Mmm... Look here to begin with. Then, a basic search on our forum would have normally led you here too...

I'm not too surprised this XPS 720 is problematic: it's based on nVidia nForce 680i chipset, not an Intel one. So, you're probably going to need specific kexts to handle that. You probably won't be able to boot successfully with standard IOATAFamily kext.

@Diddlesom: please post the detailed hardware specs, otherwise people who have no experience on this particular machine won't even be able to help you.

-> PM

Look at the inventory of supported/unsupported wifi card in R&D section of the forum. There are many cards you can choose from.

Which exact version of Lion are you installing and what kind of wireless card do you have? If Intel, remove it or disable it in BIOS; it'll need replacement since unsupported.

Not necessary. Now, will you get on with it?

Add the attached kext to your /Extra/Extensions folder (on USB installer and/or target HDD) and run myFix (quick). Then report back please. AppleACPIPlatform.kext.zip

That's it for the installation, assuming you have a myHack build... Download sections of this very site or Hackintoshosx.com are usually good places and, of course, the VoodooHDA repository on sourceforge. But it doesn't matter where you get Voodoo audio kext from, what matters is that you get and test different versions.

I had never considered those Xeon CPU in the Vostro; I didn't know it could fit and run (never looked at LGA775 vs LGA771)... I may try if I can get hold of one, but there probably wouldn't be much gain over my existing top of the line E8600 C2D: http://ark.intel.com/fr/compare/35605,36608

Or follow the article on that matter that was published in the Articles section of the web site.

Thread is not useless, it's a potential solution for those machines with BIOS where SATA mode may not be configurable and OS X installer does not see the HDD. I think that was reported for other Dell desktops like some Optiplex 745 or 755. Something like that anyway.

Mmm, maybe an incompatible USB key or a Chameleon package that is too old if you're doing all this from Leopard... Which version is it?

I found I did not need any patched IOATAFamily kext on the Vostro 200; using plain vanilla kexts suffice.

Interesting solution for SATA 6 capability (and AHCI SATA mode) for those older PCs that can be limited to SATA 1.5 or SATA 3 specs. You just used a PCIe x1 riser cable, right? Note that some of those Dell BIOS can actually be modified to unlock AHCI SATA mode for the motherboard controller. On unmodified BIOS, I understand AHCI is implicitly available by selecting RAID mode (without actually configuring any RAID array). I've been using such a modified BIOS on my own Vostro 200 for the last 3 years or so and been running with the onboard controller SATA mode set to AHCI since. Details are available here and here.

Great, so we can expect some of those savings in return?

Ok, bootpack sorted in original guide thread. Please note that you would normally be able to get rid of that AppleACPIPlatform kext in /E/E once you're up and running (I don't have it since 10.8.3 or 10.8.4).

Mmm, weird... no LAN kext in the pack! That needs immediate fixing... AppleBCM5751Ethernet.kext.zip

To install kexts, it would be better to simply copy kexts to /E/E and install them with myFix (quick). Regarding the LAN interface, you're running on the Broadcom kext from the bootpack, right?

VoodooHDA will not readily affect your future updates no; audio may no longer work after an OS X update and you could then find yourself looking at updating VoodooHDA too, but only one way of knowing after you possibly get audio working with Voodoo. It's easily installed and removed if need be. Could you please create your IOReg output with the attached copy of IORegistryExplorer v2.0. Later versions can give issues. IORegistryExplorer.zip
