Hi all!

I'm quite new to all this staff and I want to install Snow Leopard on my PC. My PC's parameters are:

• M/B - Asus P5B Deluxe
• CPU - Intel Core2Duo E6600
• Video - Asus EAX1950PRO 256M

I want to make my DSDT maximal good (and right). So, what do I need to change (fix) in it (also, please explain what does each change do)?
I have downloaded DSDTSE and there are lots of fixes there but I don't understand all of them (and I don't want to do something I don't understand). For example, SATA fix seems to be for ICH9 chipset (and mine is ICH8R).

Also, what other staff do I need for my system set up (kexts, etc.)?

Sorry for maybe simple things I'm asking, don't think I'm lazy to do some googling, I actually did a lot of googling but there are so much information (sometimes they are contradictory) and I can't find the right route.

Thanks.

Best,
Mika

Read the ACPI specs then ask very specific questions. Find them here.

Hi,

I looked at the ACPI specs (although haven't read all 600 pages) and I think I'm familiar with it. But how can I guess that something is "wrong" and should be fixed (and how)? For example, how could I knew that changes needed to be done in HPET device?
So, my first question is what things can be (should be) fixed in DSDT?
The second question is which fixes depend on my hardware (for example, I've looked at DSDTSE "Native SATA AHCI hack" fix and it seems that the code is written for "ICH9-R SATA/AHCI Controller" but I have ICH8R chipset)?

Thanks.

Your dsdt was written for windows, not os x. Typically, the first thing I do is look at OSI calls and get the table to answer the right os, Darwin. Grab a dump from a mac with your chipset for comparison.

You are looking for issues with functionality, i.e. sleep, wake, irq conflicts... If you lack functionality that has anything to do with power management, it could probably be resolved with a dsdt.



Do you have a laggy system? Does AppleIntelCPUPowerManagement load? I would recommend applying THe KiNG's IRQ fix regardless if you have the issues posted in that thread.



What's not functioning properly? Once you resolve those issues you should optimize.



I don't use that app so I have not looked at that patch. Is your sata in ioreg? Do you have the "orange icon" issue? Do you have any other issues with your issues with sata? Is there even anything wrong with your sata?

Download the docs for ICH9-R and ICH8R, study the patch and learn what its doing, compare/edit as needed.

As I stated before, you need to do research and you will be able to answer all of your questions for yourself.

Thanks for comprehensive answer. Now I have a straight route to follow
