Hi, just installed 10.5.2 rev.2 on my system (nForce4, Opteron 185, 8800GT, external USB disk) - works like a charm, just like the previous rev. Thanks Zeph, great work!!
Shutdown is a bit iffy and DVD playback doesn't work, I'm assuming this is to do with my graphics card? Neither are show-stoppers though.

Anyway. I installed ext2fsx, I have an internal drive with a NTFS and an ext3 partition. NTFS is read just fine (with ntfs-3g), but on startup I'm told that "the system extension /Library/Extensions/ext2fs.kext was installed improperly and cannot be used". So of course I can't mount my partition with ExtFSManager either. Anyone here seen similar problems?

Many thanks,
Mike

for Shutdown problem go to irc.osx86.hu and try the Appleacpi fix reboot/shutdown or another kernel with shutdown fix, for DVD go here and download the new applesmbios and for ext2fs.kext correct the permissions (chmod/chown) or install again using kexthelper.

Thanks for the reply! I have no problem with chown'ing... but I downloaded the AppleACPIPlatform.kext from OSx86.hu, and I'm not quite sure how to install it. Do I just copy it over my current files? I don't expect to be spoon-fed, but if you could point me to a place that has some sort of instructions, I'd be really grateful! Thanks in advance for your time, Mike

1. Copy the (new) kext files to /System/Library/Extensions

2. Open the Terminal & type the following Commands (hit enter after each line):

sudo -s (-> your root password)

sudo chown -R root:wheel /System/Library/Extensions/[NAME].kext

sudo chmod -R 755 /System/Library/Extensions/[NAME].kext

rm -r /System/Library/Extensions/Caches

reboot

Now use -f at boot to force the rebuilding of kext files.

Thanks for all the help!
Changing the permissions for ext2fs.kext did indeed get it working.
Sadly replacing my AppleACPIPlatform.kext and AppleSMBIOS.kext didn't work - in fact, they stopped my PS/2 keyboard and mouse from working! Fortunately I had a USB mouse and keyboard lying around, so I copied back my previous kext's. So now I'm back to square one. The shutdown irregularities are not that big a deal, but when I start the DVD Player I get:
"There was an initialization error - A valid video device could not be found for playback. [-70017]"
Is this something to do with my 8800GT card? Do I need to edit some plists inside a kext maybe?

Thanks again whether you are able to help or not, Mike

did you try the mach_kernel with shutdown fix? do you have CI/QE for your 8800gt ? if so, try with marvin utility, maybe you need some kind of cpuid ...

I thought it's included in Zeph's 10.5.2 rev.2?

Core Image: Software
Quartz Extreme: Not Supported

I'm assuming that's the problem. I don't think anyone has got QE working with a 8800GT, or am I wrong?

Thanks

you´re wrong, you need edit the info.plist for nvdaresman, geforce ,NVDAN50hal.kext and put only your device ID,

Or as I said in another thread, just follow this little guide:

got CI and QE working now and therefore DVD playback too! Yay :-D

Thanks for the help guys.

How do you change the permissions to get the kext working? I am getting the same error. Also, where is the kext located on the DVD? In the extensions folder? Please let me know. Thank you very much.
