Success this time........even Apple release 'problem' apps......LOL

 

I will look at a DSDT graphics patch for you as soon as I can find some free time........work is always very busy for me....I will PM you the DSDT to try as it could take a few iterations to get it working because of the dual PCB....

 

I may not have time until the weekend.......

Thank you verdant, that will be amazing :) thanks for all the help!

 

When ever works best for you, i barely find time myself, which is why I keep coming back to the PC and getting OSX to work on it. So many thanks in advance!

 

Some other notes, I tried to do a stress test on the SATA last night, which seemed to always be the issue. I used your lion and mountain lion support files folder and duplicated them many times and compressed them to produce a zip file of about 2.5GB, I then had the computer uncompress it, duplicate it more etc... I was able to get sustained read and write at (i think about 50mb/s, peaking at 100mb/s if memory serves).

 

Now this is only on disk operations, So i dont know if its a real test i can rely on but previously that kind of stuff would have OSX lock up... so i think the changes to the bios made a big difference :) Iv saved your nforce bios setup table for future reference. I will continue to test things and play around with the system.

See Post #6 Issue 1.......also confirm

 

1. That in your BIOS you have set them according to my OS X settings template for 780i chipset MOBOs (see here in the section 'BIOS SETTINGS TEMPLATE FOR 750i, 780i, 790i and 790i Ultra NVIDIA nForce Series 7 MCP chipset based Intel CPU MOBOs'; especially:

 

RAID Enable [Enabled]

SATA 0 Primary RAID [Disabled]

SATA 0 Secondary RAID [Disabled]

SATA 1 Primary RAID [Disabled]

SATA 1 Secondary RAID [Disabled]

SATA 2 Primary RAID [Disabled]

SATA 2 Secondary RAID [Disabled]

 

to allow you to set the Serial-ATA Controller to [All Enabled].....this because when you set RAID Enable to [Disabled], all SATA functions are changed to Disabled.

 

2. That you have a IDE (PATA) DVDRW jumper-set and connected to the MOBO as Master via an 80-wire IDE cable; see here in the section 'CORRECT IDE (PATA) DEVICE JUMPER SETTING AND CABLE CONNECTING'

 

1. I have already set everything correctly in the BIOS according to the guides.

2. Are you saying that I NEED an IDE DVD drive? I was under the impression that the instructions were only if you have any IDE drives, then you had to set the jumpers. Both my hard drives and Blu-ray writer are SATA.

 

I'm guessing I will need a modded DSDT. Wouldn't know where to begin on that one. :P

 

I appreciate all your help.

As far as my own experience goes, the AppleNForceATA.kext does not work with SATA optical drives for read/write operations.....if you want to install OS X via a bootable DVD onto your 780i MOBO PC (but you should be able to BIOS boot from a bootable USB flash drive....?), then you will need an IDE DVD drive connected as Master........

I have tried with USB flash many times and got the same problem. I just tried USB with Pandora (first time) and got further. It got to [ PCI configuration begin ] and hung for a while, then the monitors lost signal and nothing. I tried with PCIRootUID=1 GraphicsEnabler=Yes -v and it got to the grey screen with the twirly cursor then kernel panic'd. Maybe if I got the right combination of flags I could get it to work now. What flags would you try?

 

Thanks again

You can try booting with

 

-v npci=0x2000 PCIRootUID=1 GraphicsEnabler=Yes

 

or if that does not work, try

 

-v npci=0x3000 PCIRootUID=1 GraphicsEnabler=Yes

 

BUT as I said before, read Post #6 Issue 1.......

 

Also, temporarily disconnect your SATA Blu-ray writer from the MOBO.....

 

There should be no problem in installing OS X on your 780i MOBO....... but it will be difficult to be of more help because you have not indicated that you are following my nForce Mountain Lion install guide step-by-step for the USB flash drive method......and so I cannot guess why you are having USB installer problems.....

 

You can also try adding cpus=1 maxmem=2048 to the boot flags.......

 

Next time you get a screen freeze when booting in verbose mode, post a full screen image showing the boot screen........however I will be offline now for the next 12 to 16 hours......

I did follow your guide step by step with USB and later with DVD and had the previous problems. However I just tried the Pandora USB with PCIRootUID=1 GraphicsEnabler=Yes -x -v and made it to the installer screen!!! YAY! I'll let you know how it goes from there.

Using the -x boot flag boots you in Safe Mode loading only the basic Apple system kexts.......

 

Hope you install OS X Mountain Lion successfully.......:)

{censored}, it doesn't recognize any of my hard drives (3). My BIOS does not have any settings for AHCI. I thought that by enabling RAID it would assume AHCI. I set up everything in the BIOS according to the the pdf in the guide.

Enabling RAID in BIOS implicitly enables the same essential functionality as AHCI mode, so that is not the issue.

 

Does your Pandora USB installer contain and hence load the AppleNForceATA.imk64bit.kext when booting..........?

 

Did you try temporarily disconnecting your SATA Blu-ray writer from the MOBO........?

 

This is my last post for today......

No idea. It has very limited options and that's not one of them. I'm assuming it doesn't.

 

Did you try temporarily disconnecting your SATA Blu-ray writer from the MOBO........?

 

Yes. No luck.

 

I tried a different path and cloned the hard drive from my Gigabyte mobo PC which is running ML 10.8.3 and put it in my nForce PC after installing AppleNForceATA.imk64bit.kext. I got it to boot into safe mode using PCIRootUID=1 GraphicsEnabler=Yes -x -v. I got the settings in Chameleon so that I only have to use the -x. Just can't figure out what I need to do to boot without safe mode.

When you followed my guide for preparing the nForce USB flash drive OS Mountain Lion installer in Post #1 Part B. Step [8], please confirm that you placed these kexts

 

FakeSMC.kext

EvOreboot.kext

NullCPUPowerManagement.kext

AppleRTC.MLion.Patched.kext

AppleNForceATA.imk64bit.kext

 

from the verdant_Mountain Lion_Support_Files_v1.0 folder, into /Extra/Extensions/ on the USB flash drive Mac OS X Base System volume...

 

Focus on getting OS X up and running in simple VESA mode, i.e. with all NV* and Ge* kexts temporarily removed from /S/L/E and once you confirm that it is running 100% OK apart from the graphics side, then graphics can be sorted out via a patched DSDT.aml file hopefully......

They will be on the DVD so if you can borrow a IDE DVDRW temporarily you should be able to install OS X using the DVD.......

While unrelated to the problem above, i thought it might be worth it to note...

 

Sometimes on USB installers, (Flash) depending on the speed of the flash, the installer can sometimes come up, and enter the grey screen just before you get the welcome message, the mouse pointer will turn into the spinning wheel and the computer will not seem to do much. Iv seen via testing when I directly clone the same flash disk to a spare USB hard drive, that the installer is just transferring files around and appears to have crashed, but is actually doing something (even if the activity light doesn't seem to flash)

 

I found this after waiting for 10minutes with a grey screen, and then getting bored and going to watch TV for a while... when i came back, the installer was waiting for me.

 

Soooo if you can get into the grey screen, it is often good to leave it until you are very very sure that it is not going to work.

Ok I have tried so many combinations and the only way I can boot into OSX is in safe mode. I'm thinking it must be a kext. If I move all the kexts except the ones I absolutely need to a backup folder, I can see if that is the case and then narrow it down. Can someone please tell me which kexts must be in the extensions folder in order for it to boot so I can test this theory?

I already knew I needed those and I tried it with only those in it. It will not boot even in safe mode. I had to disconnect the hard drive and hook it up to my other machine running ML and put all the kexts back in and repair permissions before I could get it to boot again in my main computer. There obviously are other kexts it needs in order to boot. I guess I can try trial and error until I figure it out.

 

Thanks

Found the problem! I finally figured how to extract and patch my DSDT using Chameleon Wizard. It works now!! Now to get my sound working... :)

Have you sorted your audio yet?

Not yet but thanks for asking. I tried various different versions of Voodoo and they seem to work but the volume is so low that if I turn my speakers all the way up I can just hear it. Any suggestions?

 

Thanks again

I got the volume up where it needs to be by maxing out the input gain as suggested here:

 

http://www.insanelym...3/#entry1919468

 

Problem is, it won't stay there. Everytime I reboot, it goes all the way back down.

 

Nevermind I didn't read the part about "Save settings of VoodooHDA.prefPane by adding /Applications/VoodooHdaSettingsLoader.app to Login Items".

 

It saves the settings now. :)

Good to see your audio sorted.....AFAIK your 780i MOBO uses the Realtek ALC888 codec/chipset......

      nForce OS X El Capitan (OS X 10.11.6) APP STORE DOWNLOAD INSTALL GUIDE
      on a Series 6 or 7 nForce chipset / Intel CPU MOBO
      (and some other BIOS-based MOBOs as well, e.g. Asus P5Q, P5Q Pro, P5Q-E, P5Q Deluxe)
       
      *************************************************************
      INTRODUCTION
      *************************************************************
       
      A. Motherboard and Chipset Applicability:
       
      1. Series 6 or 7 nForce chipset / Intel CPU MOBOs
       
      This guide is primarily focussed on installing and running OS X El Capitan on a Series 6 or 7 nForce chipset / Intel CPU BIOS-based MOBOs with an nVidia graphics card.
       
      {a} This is simply because I have an Asus P5N32-E SLI Plus  650i nForce chipset + Intel Q6600 CPU MOBO + GeForce 9800GT 512MB graphics card........but what works for the 650i should and invariably does work for the 650i Ultra, 680i, 750i, 780i, 790i, and 790i Ultra.....hence my topic tags....
       
      {b} Note that in my topic tags, I say that this guide may only possibly be applicable to the 630i chipset.
      This is because it is still my current understanding is that the following nForce chipsets are not fully AHCI compliant and so can be used with imk's 64bit version (or subsequent versions of the AppleNForceATA.kext, such Tora Chi Yo's AppleNforceATA 1.0.6 version based on the AnV 1.0.4 32/64 Version etc.):
       
      nForce 430/410 (MCP51),
      nForce 590/570/550/680i/650i/780i/750i/790i (MCP55)
      nForce 430/405/400 (MCP61); nForce 560/520 (MCP65)
      nForce 630a (MCP67)
       
      Furthermore, the MOBOs using one of these nForce chipsets usually have the BIOS option to set the enable nForce SATA Controller and require SATA RAID to be Enabled (implicitly enabling AHCI mode) even when not running a RAID system, for the NForceATA.kext to work.
      In contrast, the following nForce chipsets are/may be fully-AHCI compliant and so do not/may not work with the AppleNForceATA.kext:
      nForce 560/520 (MCP65) and nForce 630a (MCP67); nForce 630i/620i/610i (MCP73), nForce 730a/720a/710a (MCP78) and nForce ION (MCP79) nForce chipsets (MCP65 and higher) support the advanced SATA features in the AHCI standard, such as NCQ etc.
      The MOBOs using one of these nForce chipsets usually have the BIOS option to set the nForce SATA Controllers to "AHCI Mode" instead of "IDE Mode".
       
      {c} As I use an nVidia graphics card, the guide is naturally written from an nVidia perspective; nevertheless, I hope that owners of a Series 6 or 7 nForce chipset / Intel CPU MOBO with an ATI graphics card will use it too.
       
      For help with:
      (i) AMD/ATI graphics cards, IM is your friend......
      (ii) For help with mixed multiple AMD/ATI and/or nVidia graphics cards and /or multiple displays, Google is your friend......e.g. aqua-mac, netkas, and later others.......
       
       
      2. Non-nForce chipset + Intel CPU MOBOs
       
      Non-nForce chipset + Intel CPU MOBOs users may also be able to use the guide, or at least also find it interesting and even helpful in places too.......
       
      I say this because:
       
      {a} Each reader's MOBO brand/model typically has to have its own custom setup for DSDT/audio/networking/video etc.
       
      {b} It is primarily the need for the AppleNForceATA.imk64bit.kext in /Extra/Extensions/ or in /System/Library/ Extensions/ and nForceLAN.0.64.5.kext in /System/Library/ Extensions/, as well not being able to use a SleepEnabler.kext and having issues with sleep that distinguishes nForce chipset + Intel CPU MOBOs from non-nForce chipset + Intel CPU MOBOs rather than the basic procedures for installing OS X.........
       
      Hence,  I have also used my USB installer (produced using this guide) with just a DSDT.aml file swap (as any nForce chipset-specific kexts in /System/Library/Extensions are not loaded into the kernel when OS X is running on a non-nForce chipset MOBO) to suit each MOBO, to install OS X 10.11.6 onto my Asus P5Q, P5Q Pro, P5Q-E and P5Q Deluxe MOBOs......
       
       
      3. Bootloader Choice 
       
      Firstly, may I say that I am very pleased with all the parallel progress being made with the Clover and Enoch (Chameleon) boot loaders as they both allow OS X El Capitan and Mac OS Sierra etc. to be booted on PCs.......  
       
      However,  as the user of multiple BIOS-based 'legacy LGA775' MOBOs, I am especially thankful for the efforts of ErmaC and Micky1979 (not forgetting the original efforts of all the Chameleon team) in continuing to develop the Enoch (Chameleon) boot loader to the extent that it can successfully boot OS X El Capitan (and Mac OS Sierra) on BIOS MOBOs, and it is the boot loader (r2839) that I am currently using for OS X El Capitan.
       
      My primary reason for using the Enoch (Chameleon) boot loader to boot OS X 10.11.6 is that I previously used the Chameleon boot loader itself to boot OS X 10.5.8 through to OS X 10.10.5 (to which OS X 10.11.5 has now been added) all on a single MBR HDD and mostly mirrored on a single GPT HDD, along with Windows 7 and Linux on my Asus P5N32-E SLI Plus  650i MOBO.
       
      Nevertheless, if and when time allows, I will investigate the use of the Clover bootloader in legacy mode for comparison and interest. 
       
      ***************************************************************************************
       
      This will be a "live guide" that will evolve in length depending on:
       
      (i) my very limited free time (hence my only finding some free time now to install OS X 10.11.6 as my 'real life' is so busy    ) and
       
      (ii) the continued level of interest and need via posts in this topic from other 'die-hard' nForce chipset + Intel CPU MOBO users (whose nForce MOBOs simply refuse to 'die', preventing an upgrade excuse!    ), especially IM members who have followed my previous nForce install guides... 
       
      So, please read the current online "live" guide before attempting to follow it, even if you had previously followed an earlier version successfully.....
