Yep looks like that might have been it. Removed that kext and so far each shutdown/reboot looks to take normal amount of time. THX again Herve´!

One more question....every other time I shut down the OS take about 5 minutes to shut down (just shows a white screen with the mouse cursor present).....then the spinning 'beach ball' is shown and then it shut downs. Any thoughts? Should I start another thread? THX again! JD31

Excellent! Thank you again!

BTW...do you guys (or Herve) know what KEXT was missing from this bootback?

That did it! I was able to finally install Mountain Lion. It was whatever missing KEXT in the D830 NVIDIA bootpack. The GUI installer did complain (at the end of the hard drive installation) that it was unable to reboot I just rebooted using the USB install key and ran the latest EDP (easy as pie!) Thank you (everyone) for your support!!

Hello Herve, THAT WORKED! It looks like newest bootpack from this site gets past the [ PCI Configuration Begin] screen and into the ML installer GUI! I'm now in the process of installing ML!!!! Excellent work! I'll post my end result once I'm done. THX again and take care. JD31

THX Herve! I'll try it in the AM tomorrow to see how it goes. So far nothing with all the suggestions above. BTW I was given a modified DSDT zip file....how would I add/prep the files contained in the ZIP file onto the USB key?

Hello Bronxteck...same thing! Stuck at [ PCI Configuration begin] Any special boot options? I'm basically just booting in 'verbose' mode.

THX Bronxteck! I'll try it first thing tomorrow and let you know. JD31

[PCI Configuration Begin ]

Downloaded legit copy from App Store but still nothing!!

As per this post: https://osxlatitude.com/index.php?/topic/1945-dsdtssdt-patching/page__p__14118__hl__dsdt__fromsearch__1#entry14118 ...I'm attaching the DSDT, SSDT, PCI Dump and Devices Dump in this post!!! I'll also email them to the email address indicated in the post. THX everyone again for all your help on this one!!!! JD31 d830.zip

In the process of doing so......since the hard drive has no OS installed, had to install Windows to get this process going......give me a few and I'll get back to you! thx!

Bump.....waiting for someone to help!!! Does anyone have a custom Bootpack that will work?

Nope...same thing. Stuck at PCI Configuration Begin..... My USB key is a SanDisk Cruzer U3......after a while it goes into a pulsating mode (like it's asleep)....that's all that happens. I've also tried with 2 different USB keys and same outcome!
