Are DSDT files for all OS X versions? or do I need different DSDT files for Mavericks, Lion, etc.

IF I FOUND THE DSDT FILE FOR MY MOTHERBOARD, does the same DSDT file works for all OS X versions, from Snow Leopard to Mavericks 10.9.2? or do I have to find a different DSDT file for each version of OS X depending on which version I am installing?

Just needed some clarification. THANK YOU FOR ALL YOUR HELP.

MY current hardware is as follows: Gigabyte GA-Z68M-D2H rev1.0; Intel Core i5-2500K; 250GB Samsung 840 EVO SSD with dual boot partition; 8GB DDR3-1600MHz Corsairs Avenger; USB keyboard and mouse; current video card: GeForce 9600 GSO 768MB and Intel HD 3000 --> Looking to upgrade to GeForce GT 650 Ti 1GB DDR5 and HD3000.

PS: One Final, just-in-case-you-know question: Anyone got a GeForce 9600 GSO 768 or variant to work under Mavericks? I know it was a hassle getting it to work properly under Snow Leopard, but just in case i can save myself the purchase of a replacement video card.

PPS: Is there a special installation guide to install Mavericks 10.9.2 with support for both integrated HD 3000 video card and a 2nd discrete video card? what do i select on multibeast?

With regard to your DSDT, it is not dependant on the OSX version, but rather the bios version of your motherboard. So, if you have a DSDT compiled against bios version F5 (As an example only) then it will work for any OSX version while ever your bios remains on the same F5 version. If you then updated your bios to a newer version, say F6, you would then need to recompile the DSDT for that newer bios version. You can then use the newer DSDT, and no need to do any reinstall or anything.

Essentially the DSDT depends on ths bios version, but not the OSX version.

Thank you for your informed clarification. I made sure the BIOS version matched, but I was going to use the same DSDT file I used on my SL build when I was about to upgrade to Mavericks, so it seemed strange. Thanks.

Is there a program that I can use to recompile the DSDT file when the BIOS version changes? So far I have relied on the DSDT file provided by tonymacx86.com. In fact, I purchased the motherboard specifically for the ones that tonymacx86 had DSDT for.

Finally, is there a benefit to flashing my motherboard to the new UEFI instead of the current BIOS? I might have missread, but UEFI does not require DSDT?? I found it hard to track down all the things that needs to be done differently under UEFI (for Win7 installation and OS X HackIntosh installation), so unless there are major advantages under Win7 or under HackIntosh, I plan to ignore learning about it. But if it makes my HackIntosh more like a real Mac (fewer incompatibility), or more stable, or significantly faster, then I should learn how to install Win7 and Mavericks in my HackIntosh.


Thank you again for the education. and thank you for any other insight you or anyone has.

Search for and download a program called MacIASL; that is the best one I have found for compiling and decompiling a DSDT. It is linked here in the forums if you do a quick search for it.

DSDT files are available for the Z68 boards and you should use them if possible. If one is not available for the bios version you have then ask for one to be created. I think most versions are catered for though.

Technically, DSDT's are not required for UEFI bios's, but, I understand there have been some issues with the early UEFI ones; they were more like cludges than proper UEFI setups. Also, even with a newer UEFI bios such as the 7 and 8 series boards, although the DSDT isnt needed for basic operation, it may still be needed to help enable extra functionality such as HDMI, third party wifi / bluetooth etc.

I have a Gigabyte Z68MX-UD2H-B3 here. I tried the UEFI bios they issued and almost immediately reverted back to the previous non-UEFI one, since it created more issues than it solved. I've read the same from a few other users too. Think carefully before you flash it, since reverting back isn't so straight forward either.

My recommendation would be to make all best effort to get everything working using your existing bios and matching DSDT. If that doesn't work, then research the UEFI functionality further so you can make an informed decision as to whether it is likely to work for you by switching to the UEFI version.

There were a lot of forum posts regarding this when those early UEFI versions were released so you should be able to find plenty of nuggets of good information.

Hi

To me, is a DSDT needed, depends on a few factors;

- is there no uefi bios you are going to have to create one or download one.
- if you have a uefi bios, you need to create one to get audio over hdmi working, usb power upgrade, sleep etc. working
- it also depends on the manufacturer and how much effort did they put in the bios.

Audio over hdmi can be done via SSDT or DSDT... If that is wanted or needed you have no choice afaik.

Basic functionality can be achieved without a DSDT, mostly. But sticking a bit more than a keyboard on a USB port seems basic to me but it's not giving that OOB. A fully functioning Hackintosh still needs edits AFAIK.

What is a AFAIK? How does it make a Hackintosh fully functional? How do I get/make this?

Thanks

LOL,

AFAIK = As Far As I Know
